 # Agents and ingestion tools

 Historically, many multiple popular agents and ingestion tools have worked with Elasticsearch OSS, such as Beats, Logstash, Fluentd, FluentBit, and OpenTelemetry. OpenSearch aims to continue to support a broad set of agents and ingestion tools, but not all have been tested or have explicitly added OpenSearch compatibility.

-As an intermediate compatibility solution, OpenSearch has a setting that instructs the cluster to return version 7.10.2 rather than its actual version.
-
-If you use clients that include a version check, such as recent versions of Logstash OSS or Filebeat OSS, enable the setting:
-
-```json
-PUT _cluster/settings
-{
-  "persistent": {
-    "compatibility": {
-      "override_main_response_version": true
-    }
-  }
-}
-```
+As an intermediate solution, we are adding a [version value](https://github.com/opensearch-project/OpenSearch/issues/693) to `opensearch.yml`. This change will let you set OpenSearch 1.x clusters to report version 7.10.2 (or any other arbitrary value). By reporting 7.10.2, the cluster will be able to connect with tools that check for a particular version number.

 For a longer term solution, we plan to create an OpenSearch output plugin for Logstash. This plugin *does not exist yet*, but we've included it in the compatibility matrices below based on its expected behavior.

-# Java high-level REST client
-
-The Elasticsearch OSS Java high-level REST client allows you to interact with your OpenSearch clusters and indices through Java methods and data structures rather than HTTP methods and JSON.
-
-You submit requests to your cluster using request objects, which allows you to create indices, add data to documents, or complete other operations with your cluster. In return, you get back response objects that have all of the available information, such as the associated index or ID, from your cluster.
-
-## Setup
-
-To start using the Elasticsearch OSS Java high-level REST client, ensure that you have the following dependency in your project's `pom.xml` file:
-
-```
-<dependency>
-  <groupId>org.elasticsearch.client</groupId>
-  <artifactId>elasticsearch-rest-high-level-client</artifactId>
-  <version>7.10.2</version>
-</dependency>
-```
-
-You can now start your OpenSearch cluster. The 7.10.2 high-level REST client works with the 1.x versions of OpenSearch.

+
+# Advanced configurations
+
+This section describes how to set up advanced configuration options, like referencing field values and conditional statements, for Logstash.
+
+## Referencing field values
+
+To get access to a field, use the `- field` syntax.
+You can also surround the field name by square brackets `- [field]` which makes it more explicit that you're referring to a field.
+
+
+For example, if you have the following event:
+
+```bash
+{
+  "request": "/products/view/123",
+  "verb": "GET",
+  "response": 200,
+  "headers": {
+  "request_path" => "/"
+  }
+}
+```
+
+To access the `request` field, use `- request` or `- [request]`.
+
+If you want to reference nested fields, use the square brackets syntax and specify the path to the field. With each level being enclosed within square brackets: `- [headers][request_path]`.
+
+You can reference fields using the `sprintf` format. This is also called string expansion. You need to add a % sign and then wrap the field reference within curly brackets.
+
+You need to reference field values when using conditional statements.
+
+For example, you can make the file name dynamic and contain the type of the processed events - either `access` or `error`. The `type` option is mainly used for conditionally applying filter plugins based on the type of events being processed.
+
+Let's add a `type` option and specify a value of `access`.
+
+
+```yml
+input {
+  file {
+    path => ""
+  start_position => "beginning"
+  type => "access"
+  }
+  http {
+    type => "access"
+  }
+}
+
+filter {
+  mutate {
+    remove_field => {"host"}
+  }
+}
+
+output {
+  stdout {
+    codec => rubydebug
+  }
+file {
+  path => "%{[type]}.log"
+  }
+}
+```
+
+Start Logstash and send an HTTP request. The processed event is output in the terminal. The event now includes a field named `type`.
+
+You'll see the `access.log` file created within the Logstash directory.
+
+## Conditional statements
+
+You can use conditional statements to control the flow of code execution based on some conditions.
+
+Syntax:
+
+```yml
+if EXPR {
+  ...
+} else if EXPR {
+  ...
+} else {
+  ...
+}
+```
+
+`EXPR` is any valid Logstash syntax that evaluates to a boolean value.
+For example, you can check if an event type is set to `access` or `error` and perform some action based on that:
+
+```yml
+if [type] == "access" {
+...
+} else if [type] == "error" {
+file { .. }
+} else {
+...
+}
+```
+
+You can compare a field value to some arbitrary value:
+
+```yml
+if [headers][content_length] >= 1000 {
+...
+}
+```
+
+You can regex:
+
+```yml
+if [some_field =~ /[0-9]+/ {
+  //some field only contains digits
+}
+```
+
+You can use arrays:
+
+```yml
+if [some_field] in ["one", "two", "three"] {
+  some field is either "one", "two", or "three"
+}
+```
+
+You can use boolean operators:
+
+```yml
+if [type] == "access" or [type] == "error" {
+  ...
+}
+```
+
+
+## Formatting dates
+
+You can use the `sprintf` format or string expansion to format dates.
+For example, you might want the current date to be part of the filename.
+
+To format the date, add a plus sign in curly brackets followed by the date format - `%{+yyyy-MM-dd}`.
+
+```yml
+file {
+  path => "%{[type]}_%{+yyyy_MM_dd}.log"
+}
+```
+
+This is the date stored within the @timestamp fields, which is the time and date of the event.
+Send a request to the pipeline and verify that a filename is outputted that contains the events date.
+
+You can embed the date in other outputs as well, for example into the index name in OpenSearch.
+
+## Sending time information
+
+You can set the time of events.
+
+Logstash already sets the time when the event is received by the input plugin within the @timestamp field.
+In some scenarios, you might need to use a different timestamp.
+For example, if you have an eCommerce store and you process the orders daily at midnight. When Logstash receives the events at midnight, it sets the timestamp to the current time.
+But you want it to be the time when the order is placed and not when Logstash received the event.
+
+Let's change the event timestamp to the date the request is received by the web server. You can do this using a filter plugin named `dates`.
+The `dates` filter passes a `date` or `datetime` value from a field and uses the results as the event timestamp.
+
+Add the `date` plugin at the bottom of the `filter` block:
+
+```yml
+date {
+  match => [ "timestamp", "dd/MMM/yyyy:HH:mm:ss Z" ]
+}
+```
+
+timestamp is the field that the `grok` pattern creates.
+`Z` is the timezone. i.e., UTC offsets.
+
+Start Logstash and send an HTTP request.
+
+You can see that the filename contains the date of the request instead of the present date.
+
+If the passing of the date fails, the `filter` plugin adds a tag named `_datepassfailure` to the text field.
+
+After you have set the @timestamp field to a new value, you don't really need the other `timestamp` field anymore. You can remove it with the `remove_field` option.
+
+```yml
+date {
+  match => [ "timestamp", "dd/MMM/yyyy:HH:mm:ss Z" ]
+  remove_field => [ "timestamp" ]
+}
+```
+
+## Parsing user agents
+
+The user agent is the last part of a log entry that consists of the name of the browser, the browser version, and the OS of the device.
+
+Users might be using a wide range of browsers, devices, and OS's. Doing this manually is hard.
+
+You can't use `grok` patterns because the `grok` pattern only matches the usage in the string as whole and doesn't figure out which browser the visitor used for instance.
+
+Logstash ships with a file containing regular expressions for this purpose. This makes it really easy to extract user agent information, which you could send to OpenSearch and run aggregations on.
+
+To do this, add a `source` option that contains the name of the field. In this case, that's the `agent` field.
+By default the user agent plugin, adds a number of fields at the top-level of the event.
+Since that can get pretty confusing, we can add an option named `target` with a value of `ua`, short for user agent. What this does is that it nests the fields within an object named `ua`, making things more organized.
+
+```yml
+useragent {
+  source => "agent"
+  target => "ua"
+}
+```
+
+Start Logstah and send an HTTP request.
+
+You can see a field named `ua` with a number of keys including the browser name and version, the OS, and the device.
+
+You could OpenSearch Dashboards to create a pie chart that shows how many visitors are from mobile devices and how many are desktop users. Or, you could get statistics on which browser versions are popular.
+
+## Enriching geographical data
+
+You can take an IP address and perform geographical lookup to resolve the geographical location of the user using the `geoip` filter.
+
+The `geoip` filter plugin ships with a database called `geolite 2`, which is provided by a company named MaxMind. `geolite 2` is a popular source of geographical data and it's available for free.
+Add the `geoip` plugin at the bottom of the `else` block.
+
+The value of the `source` option is the name of the field containing the IP address, in this case that's `clientip`. You can make this field available using the `grok` pattern.
+
+```yml
+geoip {
+  source => "clientip"
+}
+```
+
+Start Logstash and send an HTTP request.
+
+Within the terminal, you see a new field named `geoip` that contains information such as the timezone, country, continent, city, postal code, and the latitude / longitude pair.
+
+If you only need the country name for instance, include an option named `fields` with an array of the field names that you want the `geoip` plugin to return.
+
+Some of the fields are not always available such as city name and region because translating IP addresses into geographical locations is generally not that accurate. If the `geoip` plugin fails to look up the geographical location, it adds a tag named `geoip_lookup_failure`.
+
+You can use the `geoip` plugin with the OpenSearch output because `location` object within the `geoip` object, is a standard format for representing geospatial data in JSON. This is the same format as OpenSearch uses for its `geo_point` data type.
+
+You can use the powerful geospatial queries of OpenSearch for working with geographical data.

+
+# Common filter plugins
+
+This page contains a list of common filter plugins.
+
+## mutate
+
+You can use the `mutate` filter to change the data type of a field. For example, you can use the `mutate` filter if you're sending events to OpenSearch and you need to change the data type of a field to match any existing mappings.
+
+To convert the `quantity` field from a `string` type to an `integer` type:
+
+```yml
+input {
+  http {
+    host => "127.0.0.1"
+    port => 8080
+  }
+}
+
+filter {
+  mutate {
+   convert => {"quantity" => "integer"}
+  }
+}
+
+output {
+  file {
+    path => "output.txt"
+  }
+}
+```
+
+#### Sample output
+
+You can see that the type of the `quantity` field is changed from a `string` to an `integer`.
+
+```yml
+{
+  "quantity" => 3,
+  "host" => "127.0.0.1",
+  "@timestamp" => 2021-05-23T19:02:08.026Z,
+  "amount" => 10,
+  "@version" => "1",
+  "headers" => {
+    "request_path" => "/",
+    "connection" => "keep-alive",
+    "content_length" => "41",
+    "http_user_agent" => "PostmanRuntime/7.26.8",
+    "request_method" => "PUT",
+    "cache_control" => "no-cache",
+    "http_accept" => "*/*",
+    "content_type" => "application/json",
+    "http_version" => "HTTP/1.1",
+    "http_host" => "127.0.0.1:8080",
+    "accept_encoding" => "gzip, deflate, br",
+    "postman_token" => "ffd1cdcb-7a1d-4d63-90f8-0f2773069205"
+   }
+}
+```
+
+Other data types you can convert to are `float`, `string`, and `boolean` values. If you pass in an array, the `mutate` filter converts all the elements in the array. If you pass a `string` like "world" to cast to an `integer` type, the result is 0 and Logstash continues processing events.
+
+Logstash supports a few common options for all filter plugins:
+
+Option | Description
+:--- | :---
+`add_field` | Adds one or more fields to the event.
+`remove_field` | Removes one or more events from the field.
+`add_tag` | Adds one or more tags to the event. You can use tags to perform conditional processing on events depending on which tags they contain.
+`remove_tag` | Removes one or more tags from the event.
+
+For example, you can remove the `host` field from the event:
+
+```yml
+input {
+  http {
+    host => "127.0.0.1"
+    port => 8080
+  }
+}
+
+filter {
+  mutate {
+    remove_field => {"host"}
+  }
+}
+
+output {
+  file {
+    path => "output.txt"
+  }
+}
+```
+
+## grok
+
+With the `grok` filter, you can parse unstructured data and and structure it into fields. The `grok` filter uses text patterns to match text in your logs. You can think of text patterns as variables containing regular expressions.
+
+The format of a text pattern is as follows:
+
+```bash
+%{SYNTAX:SEMANTIC}
+```
+
+`SYNTAX` is the format a piece of text should be in for the pattern to match. You can enter any of `grok`'s predefined patterns. For example, you can use the email identifier to match an email address from a given piece of text.
+
+`SEMANTIC` is an arbitrary name for the matched text. For example, if you're using the email identifier syntax, you can name it “email.”
+
+The following request consists of the IP address of the visitor, name of the visitor, the timestamp of the request, the HTTP verb and URL, the HTTP status code, and the number of bytes:
+
+```bash
+184.252.108.229 - joe [20/Sep/2017:13:22:22 +0200] GET /products/view/123 200 12798
+```
+
+To split this request into different fields:
+
+```yml
+filter {
+  grok {

+# Logstash execution model
+
+Here's a brief introduction to how Logstash processes events internally.
+
+## Handling events concurrently
+
+You can configure Logstash to have a number of inputs listening for events. Each input runs in its own thread to avoid inputs blocking each other. If you have two incoming events at the same time, Logstash handles both events concurrently.
+
+After receiving an event and possibly applying an input codec, Logstash sends the event to a work queue. Pipeline workers or batchers perform the rest of the work involving filters and outputs along with any codec used at the output. Each pipeline worker also runs within its own thread meaning that Logstash processes multiple events simultaneously.
+
+## Processing events in batches
+
+A pipeline worker consumes events from the work queue in batches to optimize the throughput of the pipeline as a whole.
+
+One reason why Logstash works in batches is that some code needs to be executed regardless of how many events are processed at a time within the pipeline worker. Instead of executing that code 100 times for 100 events, it’s more efficient to execute it once for a batch of 100 events.
+
+Another reason is that a few output plugins group together events as batches. For example, if you send 100 requests to OpenSearch, the OpenSearch output plugin uses the bulk API to send a single request that groups together the 100 requests.
+
+Logstash determines the batch size by two configuration options⁠---a number representing the maximum batch size and the batch delay. The batch delay is how long Logstash waits before processing the unprocessed batch of events.
+If you set the maximum batch size to 50 and the batch delay to 100 ms, Logstash processes a batch if they're either 50 unprocessed events in the work queue or if one hundred milliseconds have elapsed.
+
+The reason that a batch is processed, even if the maximum batch size isn’t reached, is to reduce the delay in processing and to continue to process events in a timely manner. This works well for pipelines that process a low volume of events.
+
+Imagine that you’ve a pipeline that processes error logs from web servers and pushes them to OpenSearch. You’re using OpenSearch Dashboards to analyze the error logs. Because you’re possibly dealing with a fairly low number of events, it might take a long time to reach 50 events. Logstash processes the events before reaching this threshold because otherwise there would be a long delay before we see the errors appear in OpenSearch Dashboards.
+
+The default batch size and batch delay work for most cases. You don’t need to change the default values unless you need to minutely optimize the performance.
+
+## Optimizing based on CPU cores
+
+The number of pipeline workers are proportional to the number of CPU cores on the nodes.
+If you have 5 workers running on a server with 2 CPU cores, the 5 workers won't be able to process events concurrently. On the other hand, running 5 workers on a server running 10 CPU cores limits the throughput of a Logstash instance.
+
+Instead of running a fixed number of workers, which results in poor performance in some cases, Logstash examines the number of CPU cores of the instance and selects the number of pipeline workers to optimize its performance for the platform on which its running. For instance, your local development machine might not have the same processing power as a production server. So you don't need to manually configure Logstash for different machines.

+
+# Logstash
+
+Logstash is a real-time event processing engine. It's part of the OpenSearch stack which includes OpenSearch, Beats, and OpenSearch Dashboards.
+
+You can send events to Logstash from many different sources. Logstash processes the events and sends it one or more destinations. For example, you can send access logs from a web server to Logstash. Logstash extracts useful information from each log and sends it to a destination like OpenSearch.
+
+Sending events to Logstash lets you decouple event processing from your app. Your app only needs to send events to Logstash and doesn’t need to know anything about what happens to the events afterwards.
+
+The open-source community originally built Logstash for processing log data but now you can process any type of events, including events in XML or JSON format.
+
+## Structure of a pipeline
+
+The way that Logstash works is that you configure a pipeline that has three phases⁠---inputs, filters, and outputs.
+
+Each phase uses one or more plugins. Logstash has over 200 built-in plugins so chances are that you’ll find what you need. Apart from the built-in plugins, you can use plugins from the community or even write your own.
+
+The structure of a pipeline is as follows:
+
+```yml
+input {
+  input_plugin => {}
+}
+
+filter {
+  filter_plugin => {}
+}
+
+output {
+  output_plugin => {}
+}
+```
+
+where:
+
+* `input` receives events like logs from multiple sources simultaneously. Logstash supports a number of input plugins for TCP/UDP, files, syslog, Microsoft Windows EventLogs, stdin, HTTP, and so on. You can also use an open source collection of input tools called Beats to gather events. The input plugin sends the events to a filter.
+* `filter` parses and enriches the events in one way or the other. Logstash has a large collection of filter plugins that modify events and pass them on to an output. For example, a `grok` filter parses unstructured events into fields and a `mutate` filter changes fields. Filters are executed sequentially.
+* `output` ships the filtered events to one or more destinations. Logstash supports a wide range of output plugins for destinations like OpenSearch, TCP/UDP, emails, files, stdout, HTTP, Nagios, and so on.
+
+Both the input and output phases support codecs to process events as they enter or exit the pipeline.
+Some of the popular codecs are `json` and `multiline`. The `json` codec processes data that’s in JSON format and the `multiline` codec merges multiple line events into a single line.
+
+You can also write conditional statements within pipeline configurations to perform certain actions, if a certain criteria is met.
+
+## Install Logstash
+
+The OpenSearch Logstash plugin has two installation options at this time: Linux (ARM64/X64) and Docker (ARM64/X64).
+
+Make sure you have [Java Development Kit (JDK)](https://www.oracle.com/java/technologies/javase-downloads.html) version 8 or 11 installed.
+
+### Tarball
+
+1. Download the Logstash tarball from [OpenSearch downloads](https://opensearch.org/downloads.html).
+
+2. Navigate to the downloaded folder in the terminal and extract the files:
+
+     ```bash
+     tar -zxvf logstash-oss-with-opensearch-output-plugin-7.13.2-linux-x64.tar.gz
+     ```
+
+3. Navigate to the `logstash-7.13.2` directory.
+- You can add your pipeline configurations to the `config` directory. Logstash saves any data from the plugins in the `data` directory. The `bin` directory contains the binaries for starting Logstash and managing plugins.
+
+### Docker
+
+1. Pull the Logstash oss package with the OpenSearch output plugin image:
+
+```
+docker pull opensearchproject/logstash-oss-with-opensearch-output-plugin:7.13.2
+```
+
+1. Create a Docker network:
+
+```
+docker network create test
+```
+
+1. Start OpenSearch with this network:
+
+```
+docker run -p 9200:9200 -p 9600:9600 --name opensearch --net test -e "discovery.type=single-node" opensearchproject/opensearch:1.0.0
+```
+
+1. Start Logstash:
+
+```
+docker run -it --rm --name logstash --net test openserachproject/logstash-oss-with-opensearch-output-plugin:7.13.2 -e 'input { stdin { } } output {
+  opensearch {
+    hosts => ["https://opensearch:9200"]
+    index => "opensearch-logstash-docker-%{+YYYY.MM.dd}"
+    user => "admin"
+    password => "admin"
+    ssl => true
+    ssl_certificate_verification => false
+  }
+}'
+```
+
+## Process text from the terminal
+
+You can define a pipeline that listens for events on `stdin` and outputs events on `stdout`. `stdin` and `stdout` refer to the terminal in which you’re running Logstash.
+
+To enter some text in the terminal and see the event data in the output:
+
+1. Use the `-e` argument to pass a pipeline configuration directly to the Logstash binary. In this case, `stdin` is the input plugin and `stdout` is the output plugin:
+
+    ```bash
+    bin/logstash -e "input { stdin { } } output { stdout { } }"
+    ```
+    Add the `—debug` flag to see a more detailed output.
+
+2. Enter "hello world" in your terminal. Logstash processes the text and outputs it back to the terminal:
+
+    ```yml
+    {
+     "message" => "hello world",
+     "host" => "a483e711a548.ant.amazon.com",
+     "@timestamp" => 2021-05-30T05:15:56.816Z,
+     "@version" => "1"
+    }
+    ```
+
+    The `message` field contains your raw input. The `host` field is an IP address when you don’t run Logstash locally. `@timestamp` shows the date and time for when the event is processed. Logstash uses the `@version` field for internal processing.
+
+3. Press `Ctrl + C` to shut down Logstash.
+
+### Troubleshooting
+
+If you already have a Logstash process running, you’ll get an error. To fix this issue:
+
+1. Delete the `.lock` file from the `data` directory:
+
+    ```bash
+    cd data
+    rm -rf .lock
+    ```
+
+2. Restart Logstash.
+
+## Process JSON or HTTP input and output it to a file
+
+To define a pipeline that handles JSON requests:
+
+1. Open the `config/pipeline.conf` file in any text editor you like. You can create a pipeline configuration file with any extension, the `.conf` extension is a Logstash convention. Add the `json` codec to accept JSON as the input and the `file` plugin to output the processed events to a `.txt` file:
+
+    ```yml
+    input {
+      stdin {
+        codec => json
+      }
+    }
+    output {
+      file {
+        path => "output.txt"
+      }
+    }
+    ```
+
+    To process inputs from a file, add an input file to the `events-data` directory and then pass its path to the `file` plugin at the input:
+
+    ```yml
+    input {
+      file {
+        path => "events-data/input_data.log"
+      }
+    }
+    ```
+
+2. Start Logstash:
+
+    ```bash
+    $ bin/logstash -f config/pipeline.conf
+    ```
+
+    `config/pipeline.conf` is a relative path to the `pipeline.conf` file. You can use an absolute path as well.
+
+3. Add a JSON object in the terminal:
+
+    ```json
+    { "amount": 10, "quantity": 2}
+    ```
+
+    The pipeline only handles a single line of input. If you paste some JSON that spans multiple lines, you’ll get an error.
+
+4. Check that the fields from the JSON object are added to the `output.txt` file:
+
+    ```json
+    $ cat output.txt
+
+    {
+      "@version": "1",
+      "@timestamp": "2021-05-30T05:52:52.421Z",
+      "host": "a483e711a548.ant.amazon.com",
+      "amount": 10,
+      "quantity": 2
+    }
+    ```
+
+    If you type in some invalid JSON as the input, you'll see a JSON parsing error. Logstash doesn't discard the invalid JSON because you still might want to do something with it. For example, you can trigger an email or send a notification to a Slack channel.
+
+To define a pipeline that handles HTTP requests:
+
+1. Use the `http` plugin to send events to Logstash through HTTP:
+
+    ```yml
+    input {
+      http {
+        host => "127.0.0.1"
+        port => 8080
+      }
+    }
+
+    output {
+      file {
+        path => "output.txt"
+      }
+    }
+    ```
+
+    If you don’t specify any options, the `http` plugin binds to `localhost` and listens on port 8080.
+
+2. Start Logstash:
+
+    ```bash
+    $ bin/logstash -f config/pipeline.conf
+    ```
+
+3. Use Postman to send an HTTP request. Set `Content-Type` to an HTTP header with a value of `application/json`:
+
+    ```json
+    PUT 127.0.0.1:8080
+
+    {
+      "amount": 10,
+      "quantity": 2
+    }
+    ```
+
+    Or, you can use the `curl` command:
+
+    ```bash
+    curl -XPUT -H "Content-Type: application/json" -d ' {"amount": 7, "quantity": 3 }' http://localhost:8080 (http://localhost:8080/)
+    ```
+
+    Even though we haven't added the `json` plugin to the input, the pipeline configuration still works because the HTTP plugin automatically applies the appropriate codec based on the `Content-Type` header.
+    If you specify a value of `applications/json`, Logstash parses the request body as JSON.
+
+    The `headers` field contains the HTTP headers that Logstash receives:
+
+    ```json
+    {
+      "host": "127.0.0.1",
+      "quantity": "3",
+      "amount": 10,
+      "@timestamp": "2021-05-30T06:05:48.135Z",
+      "headers": {
+        "http_version": "HTTP/1.1",
+        "request_method": "PUT",
+        "http_user_agent": "PostmanRuntime/7.26.8",
+        "connection": "keep-alive",
+        "postman_token": "c6cd29cf-1b37-4420-8db3-9faec66b9e7e",
+        "http_host": "127.0.0.1:8080",
+        "cache_control": "no-cache",
+        "request_path": "/",
+        "content_type": "application/json",
+        "http_accept": "*/*",
+        "content_length": "41",
+        "accept_encoding": "gzip, deflate, br"
+      },
+    "@version": "1"
+    }
+    ```
+
+
+## Automatically reload the pipeline configuration
+
+You can configure Logstash to detect any changes to the pipeline configuration file or the input log file and automatically reload the configuration.
+
+The `stdin` plugin doesn’t supporting automatic reloading.
+{: .note }
+
+1. Add an option named `start_position` with a value of `beginning` to the input plugin:
+
+    ```yml
+    input {
+      file {
+        path => "/Users/<user>/Desktop/logstash7-12.1/events-data/input_file.log"
+        start_position => "beginning"
+      }
+    }
+    ```
+
+    Logstash only processes any new events added to the input file and ignores the ones that it has already processed to avoid processing the same event more than once on restart.
+
+    Logstash records its progress in a file that's referred to as a `sinceDB` file. Logstash creates a `sinceDB` file for each file that it watches for changes.
+
+2. Open the `sinceDB` file to check how much of the input files are processed:
+
+    ```bash
+    cd data/plugins/inputs/file/
+    ls -al
+
+    -rw-r--r--  1 user  staff   0 Jun 13 10:50 .sincedb_9e484f2a9e6c0d1bdfe6f23ac107ffc5
+
+    cat .sincedb_9e484f2a9e6c0d1bdfe6f23ac107ffc5
+
+    51575938 1 4 7727
+    ```
+
+    The last number in the `sinceDB` file (7727) is the byte offset of the last known event processed.
+
+5. To process the input file from the beginning, delete the `sinceDB` file:
+
+    ```yml
+    rm .sincedb_*
+    ```
+
+2. Start Logstash with a `—-config.reload.automatic` argument:
+
+    ```bash
+    bin/logstash -f config/pipeline.conf --config.reload.automatic
+    ```
+
+    The `reload` option only reloads if you add a new line at the end of the pipeline configuration file.
+
+    Sample output:
+
+    ```yml
+    {
+       "message" => "216.243.171.38 - - [20/Sep/2017:19:11:52 +0200] \"GET /products/view/123 HTTP/1.1\" 200 12798 \"https://codingexplained.com/products\" \"Mozilla/5.0 (compatible; YandexBot/3.0; +http://yandex.com/bots)\"",
+       "@version" => "1",
+          "host" => "a483e711a548.ant.amazon.com",
+          "path" => "/Users/kumarjao/Desktop/odfe1/logstash-7.12.1/events-data/input_file.log",
+       "@timestamp" => 2021-06-13T18:03:30.423Z
+    }
+    {
+       "message" => "91.59.108.75 - - [20/Sep/2017:20:11:43 +0200] \"GET /js/main.js HTTP/1.1\" 200 588 \"https://codingexplained.com/products/view/863\" \"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0\"",

+    "@timestamp" => 2021-06-13T18:03:30.424Z
+    }
+    ```
+
+7. Add a new line to the input file.
+    - Logstash immediately detects the change and processes the new line as an event.
+
+8. Make a change to the `pipeline.conf` file.
+    - Logstash immediately detects the change and reloads the modified pipeline.

+## OpenSearch output plugin
+
+To run the OpenSearch output plugin, add the following configuration in your `pipeline.conf` file:
+
+```yml
+output {
+  opensearch {
+    hosts       => "https://localhost:9200"
+    user        => "admin"

+    index       => "logstash-logs-%{+YYYY.MM.dd}"
+    ssl_certificate_verification => false
+  }
+}
+```
+
+
+## Sample walkthrough
+
+1.  Open the `config/pipeline.conf` file and add in the following configuration:
+
+    ```yml
+    input {
+      stdin {
+        codec => json
+      }
+    }
+
+    output {
+      opensearch {
+        hosts       => "https://localhost:9200"
+        user        => "admin"

+        ssl_certificate_verification => false
+      }
+    }
+    ```
+
+    This Logstash pipeline accepts JSON input through the terminal and ships the events to an OpenSearch cluster running locally. Logstash writes the events to an index with the `logstash-logs-%{+YYYY.MM.dd}` naming convention.
+
+2. Start Logstash:
+
+    ```bash
+    $ bin/logstash -f config/pipeline.conf --config.reload.automatic
+    ```
+
+    `config/pipeline.conf` is a relative path to the `pipeline.conf` file. You can use an absolute path as well.
+
+3. Add a JSON object in the terminal:
+
+    ```json
+    { "amount": 10, "quantity": 2}
+    ```
+
+4. Start OpenSearch Dashboards and choose **Dev Tools**:

-# Configure TLS for OpenSearch Dashboards
-
-By default, for ease of testing and getting started, OpenSearch Dashboards runs over HTTP. To enable TLS for HTTPS, update the following settings in `opensearch_dashboards.yml`.
-
-Setting | Description
-:--- | :---
-opensearch.ssl.verificationMode | This setting is for communications between OpenSearch and OpenSearch Dashboards. Valid values are `full`, `certificate`, or `none`. We recommend `full` if you enable TLS, which enables hostname verification. `certificate` just checks the certificate, not the hostname, and `none` performs no checks (suitable for HTTP). Default is `full`.
-opensearch.ssl.certificateAuthorities | If `opensearch.ssl.verificationMode` is `full` or `certificate`, specify the full path (e.g. `[ "/usr/share/opensearch-dashboards-1.0.0/config/root-ca.pem" ]` to the certificate authority for your OpenSearch cluster.
-server.ssl.enabled | This setting is for communications between OpenSearch Dashboards and the web browser. Set to true for HTTPS, false for HTTP.
-server.ssl.certificate | If `server.ssl.enabled` is true, specify the full path (e.g. `/usr/share/opensearch-dashboards-1.0.0/config/my-client-cert.pem` to a valid client certificate for your OpenSearch cluster. You can [generate your own]({{site.url}}{{site.baseurl}}/security-plugin/configuration/generate-certificates/) or get one from a certificate authority.
-server.ssl.key | If `server.ssl.enabled` is true, specify the full path (e.g. `/usr/share/opensearch-dashboards-1.0.0/config/my-client-cert-key.pem` to the key for your client certificate. You can [generate your own]({{site.url}}{{site.baseurl}}/security-plugin/configuration/generate-certificates/) or get one from a certificate authority.
-opensearch_security.cookie.secure | If you enable TLS for OpenSearch Dashboards, change this setting to `true`. For HTTP, set it to `false`.
-
-This `opensearch_dashboards.yml` configuration shows OpenSearch and OpenSearch Dashboards running on the same machine with the demo configuration:
-
-```yml
-opensearch.hosts: ["https://localhost:9200"]
-opensearch.ssl.verificationMode: full
-opensearch.username: "kibanaserver"
-opensearch.password: "kibanaserver"
-opensearch.requestHeadersWhitelist: [ authorization,securitytenant ]
-server.ssl.enabled: true
-server.ssl.certificate: /usr/share/opensearch-1.0.0/config/client-cert.pem
-server.ssl.key: /usr/share/opensearch-1.0.0/config/client-cert-key.pem
-opensearch.ssl.certificateAuthorities: [ "/usr/share/opensearch-1.0.0/config/root-ca.pem" ]
-opensearch_security.multitenancy.enabled: true
-opensearch_security.multitenancy.tenants.preferred: ["Private", "Global"]
-opensearch_security.readonly_mode.roles: ["kibana_read_only"]
-opensearch_security.cookie.secure: true
-```
-
-If you use the Docker install, you can pass a custom `opensearch_dashboards.yml` to the container. To learn more, see the [Docker installation page]({{site.url}}{{site.baseurl}}/opensearch/install/docker/).
-
-After enabling these settings and starting OpenSearch Dashboards, you can connect to it at `https://localhost:5601`. You might have to acknowledge a browser warning if your certificates are self-signed. To avoid this sort of warning (or outright browser incompatibility), best practice is to use certificates from trusted certificate authority.

One by one, add OpenSearch nodes to the cluster and remove Elasticsearch OSS nodes, allowing time for all indices to return to a green status prior to proceeding.

 If you use Docker Compose, we highly recommend that you perform what amounts to a [cluster restart upgrade]({{site.url}}{{site.baseurl}}/migrate/upgrade-migrate/). Update your cluster configuration with new images, new settings, and new environment variables, and test it. Then stop and start the cluster. This process requires downtime, but takes very few steps and lets you continue to treat the cluster as a single entity that you can reliably deploy and redeploy.

+# About migrating
+
+The process of migrating from Elasticsearch OSS (including Open Distro for Elasticsearch) to OpenSearch varies depending on your current version of Elasticsearch OSS, install type, tolerance for downtime, and cost-sensitivity. Rather than concrete steps to cover every situation, we have general guidance for the process.
+
+To safeguard against data loss, we recommend that you take a [snapshot]({{site.url}}{{site.baseurl}}/opensearch/snapshot-restore/) of all indices prior to any migration.

 One popular approach is to take a [snapshot]({{site.url}}{{site.baseurl}}/opensearch/snapshot-restore/) of your Elasticsearch OSS 6.x or 7.x indices, [create an OpenSearch cluster]({{site.url}}{{site.baseurl}}/opensearch/install/), restore the snapshot on the new cluster, and point your clients to the new host.

+
+# cat API
+
+You can get essential statistics about your cluster in an easy-to-understand, tabular format using the compact and aligned text (CAT) API. The cat API is a human-readable interface that returns plain text instead of traditional JSON.
+
+Using the cat API, you can answer questions like which node is the elected master, what state is the cluster in, how many documents are in each index, and so on.
+
+To see the available operations in the cat API, use the following command:
+
+```
+GET _cat
+```
+
+You can also use the following string parameters with your query.
+
+Parameter | Description
+:--- | :--- |
+`?v` |  Makes the output more verbose by adding headers to the columns. It also adds some formatting to help align each of the columns together. All examples on this page include the `v` parameter.
+`?help` | Lists the default and other available headers for a given operation.
+`?h`  |  Limits the output to specific headers.
+`?format` |  Outputs the result in JSON, YAML, or CBOR formats.
+`?sort` | Sorts the output by the specified columns.
+
+To see what each column represents, use the `?v` parameter:
+
+```
+GET _cat/<operation_name>?v
+```
+
+To see all the available headers, use the `?help` parameter:
+
+```
+GET _cat/<operation_name>?help
+```
+
+To limit the output to a subset of headers, use the `?h` parameter:
+
+```
+GET _cat/<operation_name>?h=<header_name_1>,<header_name_2>&v
+```
+
+Typically, for any operation you can find out what headers are available using the `?help` parameter, and then use the `?h` parameter to limit the output to only the headers that you care about.

-# Data streams
-
-If you're ingesting continuously generated time-series data such as logs, events, and metrics into OpenSearch, you're likely in a scenario where:
-
- You’re ingesting documents that grow rapidly.
- You don’t need to update older documents.
- Your searches generally target the newer documents.
-
-A typical workflow to manage time-series data is as follows:
-
- To split your data into an index for each day, use the rollover operation.
- To perform searches on a virtual index name that gets expanded to the underlying indices, create an [index alias]({{site.url}}{{site.baseurl}}/opensearch/index-alias/).
- To perform a write operation on an index alias, configure the latest index as the write index.
- To configure new indices, extract common mappings and settings into an [index template]({{site.url}}{{site.baseurl}}/opensearch/index-templates/).
-
-Even after you perform all these operations, you’re still not enforcing the best practices when dealing with time-series data. For example, you can modify the indices directly. You’re able to ingest documents without a timestamp field, which might result in slower queries.
-
-Data streams abstract the complexity and enforce the best practices for managing time-series data.
-
-With data streams, you can store append-only time-series data across multiple indices with a single endpoint for ingesting and searching data. It replaces index aliases for time-series data.
-
-## About data streams
-
-A data stream consists of one or more hidden auto-generated backing indices. These backing indices are named using the following convention:
-
-```
-.ds-<data-stream-name>-<generation-id>
-```
-
-For example, `.ds-logs-redis-000003`, where generation-id is a six-digit, zero-padded integer that acts as a cumulative count of the data stream’s rollovers, starting at `000001`.
-
-The most recently created backing index is the data stream’s write index. You can’t add documents directly to any of the backing indices. You can only add them via the data stream handle:
-
-![data stream indexing diagram]({{site.url}}{{site.baseurl}}/images/data_stream_indexing.png)
-
-The data stream routes search requests to all of its backing indices. It uses the timestamp field to intelligently route search requests to the right set of indices and shards:
-
-![data stream indexing diagram]({{site.url}}{{site.baseurl}}/images/data_stream_searching.png)
-
-The following operations are not supported on the write index because they might hinder the indexing operation:
-
- close
- clone
- delete
- shrink
- split
-
-## Get started with data streams
-
-### Step 1: Create an index template
-
-To create a data stream, you first need to create an index template that configures a set of indices as a data stream. The `data_stream` object indicates that it’s a data stream and not a regular index template. The index pattern matches with the name of the data stream:
-
-```json
-PUT _index_template/logs-template
-{
-  "index_patterns": [
-    "my-data-stream",
-    "logs-*"
-  ],
-  "data_stream": {},
-  "priority": 100
-}
-```
-
-In this case, each ingested document must have an `@timestamp` field.
-You also have the ability to define your own custom timestamp field as a property in the `data_stream` object. You can also add index mappings and other settings here, just as you would for a regular index template.
-
-```json
-PUT _index_template/logs-template-nginx
-{
-  "index_patterns": "logs-nginx",
-  "data_stream": {
-    "timestamp_field": {
-      "name": "request_time"
-    }
-  },
-  "priority": 200,
-  "template": {
-    "settings": {
-      "number_of_shards": 1,
-      "number_of_replicas": 0
-    }
-  }
-}
-```
-
-In this case, `logs-nginx` index matches both the `logs-template` and `logs-template-nginx` templates. When you have a tie, OpenSearch selects the matching index template with the higher priority value.
-
-### Step 2: Create a data stream
-
-After you create an index template, you can create a data stream.
-You can use the data stream API to explicitly create a data stream. The data stream API initializes the first backing index:
-
-```json
-PUT _data_stream/logs-redis
-PUT _data_stream/logs-nginx
-```
-
-You can also directly start ingesting data without creating a data stream.
-
-Because we have a matching index template with a data_stream object, OpenSearch automatically creates the data stream:
-
-```json
-POST logs-staging/_doc
-{
-  "message": "login attempt failed",
-  "@timestamp": "2013-03-01T00:00:00"
-}
-```
-
-To see information about a specific data stream:
-
-```json
-GET _data_stream/logs-nginx
-```
-
-#### Sample response
-
-```json
-{
-  "data_streams" : [
-    {
-      "name" : "logs-nginx",
-      "timestamp_field" : {
-        "name" : "request_time"
-      },
-      "indices" : [
-        {
-          "index_name" : ".ds-logs-nginx-000001",
-          "index_uuid" : "-VhmuhrQQ6ipYCmBhn6vLw"
-        }
-      ],
-      "generation" : 1,
-      "status" : "GREEN",
-      "template" : "logs-template-nginx"
-    }
-  ]
-}
-```
-
-You can see the name of the timestamp field, the list of the backing indices, and the template that's used to create the data stream. You can also see the health of the data stream, which represents the lowest status of all its backing indices.
-
-To see more insights about the data stream, use the `_stats` endpoint:
-
-```json
-GET _data_stream/logs-nginx/_stats
-```
-
-#### Sample response
-
-```json
-{
-  "_shards" : {
-    "total" : 1,
-    "successful" : 1,
-    "failed" : 0
-  },
-  "data_stream_count" : 1,
-  "backing_indices" : 1,
-  "total_store_size_bytes" : 208,
-  "data_streams" : [
-    {
-      "data_stream" : "logs-nginx",
-      "backing_indices" : 1,
-      "store_size_bytes" : 208,
-      "maximum_timestamp" : 0
-    }
-  ]
-}
-```
-
-### Step 3: Ingest data into the data stream
-
-To ingest data into a data stream, you can use the regular indexing APIs. Make sure every document that you index has a timestamp field. If you try to ingest a document that doesn't have a timestamp field, you get an error.
-
-```json
-POST logs-redis/_doc
-{
-  "message": "login attempt",
-  "@timestamp": "2013-03-01T00:00:00"
-}
-```
-
-### Step 4: Searching a data stream
-
-You can search a data stream just like you search a regular index or an index alias.
-The search operation applies to all of the backing indices (all data present in the stream).
-
-```json
-GET logs-redis/_search
-{
-  "query": {
-    "match": {
-      "message": "login"
-    }
-  }
-}
-```
-
-#### Sample response
-
-```json
-{
-  "took" : 514,
-  "timed_out" : false,
-  "_shards" : {
-    "total" : 5,
-    "successful" : 5,
-    "skipped" : 0,
-    "failed" : 0
-  },
-  "hits" : {
-    "total" : {
-      "value" : 1,
-      "relation" : "eq"
-    },
-    "max_score" : 0.2876821,
-    "hits" : [
-      {
-        "_index" : ".ds-logs-redis-000001",
-        "_type" : "_doc",
-        "_id" : "-rhVmXoBL6BAVWH3mMpC",
-        "_score" : 0.2876821,
-        "_source" : {
-          "message" : "login attempt",
-          "@timestamp" : "2013-03-01T00:00:00"
-        }
-      }
-    ]
-  }
-}
-```
-
-### Step 5: Rollover a data stream
-
-A rollover operation creates a new backing index that becomes the data stream’s new write index.
-
-To perform manual rollover operation on the data stream:
-
-```json
-POST logs-redis/_rollover
-```
-
-#### Sample response
-
-```json
-{
-  "acknowledged" : true,
-  "shards_acknowledged" : true,
-  "old_index" : ".ds-logs-redis-000001",
-  "new_index" : ".ds-logs-redis-000002",
-  "rolled_over" : true,
-  "dry_run" : false,
-  "conditions" : { }
-}
-```
-
-If you now perform a `GET` operation on the `logs-redis` data stream, you see that the generation ID is incremented from 1 to 2.
-
-You can also set up an [Index State Management (ISM) policy]({{site.url}}{{site.baseurl}}/ism/policies/) to automate the rollover process for the data stream.  
-The ISM policy is applied to the backing indices at the time of their creation. When you associate a policy to a data stream, it only affects the future backing indices of that data stream.
-
-You also don’t need to provide the `rollover_alias` setting, because the ISM policy infers this information from the backing index.
-
-### Step 6: Manage data streams in OpenSearch Dashboards
-
-To manage data streams from OpenSearch Dashboards, open **OpenSearch Dashboards**, choose **Index Management**, select **Indices** or **Policy managed indices**.
-
-You see a toggle switch for data streams that you can use to show or hide indices belonging to a data stream.
-
-When you enable this switch, you see a data stream multi-select dropdown menu that you can use for filtering data streams.
-You also see a data stream column that shows you the name of the parent data stream the index is contained in.
-
-![data stream toggle]({{site.url}}{{site.baseurl}}/images/data_streams_toggle.png)
-
-You can select one or more data streams and apply an ISM policy on them. You can also apply a policy on any individual backing index.
-
-You can performing visualizations on a data stream just like you would on a regular index or index alias.
-
-### Step 7: Delete a data stream
-
-The delete operation first deletes the backing indices of a data stream and then deletes the data stream itself.
-
-To delete a data stream and all of its hidden backing indices:
-
-```json
-DELETE _data_stream/<name_of_data_stream>
-```
-
-You can use wildcards to delete more than one data stream.
-
-We recommend deleting data from a data stream using an ISM policy.
-
-You can also use [asynchronous search]({{site.url}}{{site.baseurl}}/async/index/) and [SQL]({{site.url}}{{site.baseurl}}/sql/index/) and [PPL]({{site.url}}{{site.baseurl}}/ppl/index/) to query your data stream directly. You can also use the security plugin to define granular permissions on the data stream name.

-## Composable index templates
-
-Managing multiple index templates has the following challenges:
-
- If you have duplication between index templates, storing these index templates results in a bigger cluster state.
- If you want to make a change across all your index templates, you have to manually make the change for each template.
- If an index matches multiple templates, OpenSearch might merge the templates in an unexpected way that you discover only after an index is created.
-
-You can use composable index templates to overcome these challenges. Composable index templates let you abstract common settings, mappings, and aliases into a reusable building block called a component template.
-
-You can combine component templates to compose an index template.

-
-### Simulate multi-component templates
-
-For index templates composed of multiple component templates, you can simulate applying a new template to verify whether the settings are applied as you expect.
-
-To simulate the settings that would be applied to a specific index name:
-
-```json
-POST _index_template/_simulate_index/<index_name>
-```
-
-To simulate the settings that would be applied from an existing template:
-
-```json
-POST _index_template/_simulate/<index_template>
-```
-
-You can also specify a template definition in the simulate request:
-
-```json
-POST _index_template/_simulate
-{
-  "index_patterns": [
-    "logs-2020-01-*"
-  ],
-  "template": {
-    "settings" : {
-        "index.number_of_shards" : 3
-    }
-  },
-  "composed_of": ["component_template_1", "component_template_2"]
-}
-```
-
-The `_simulate` API returns the final settings, mappings, and aliases that will be applied to indices that match the index pattern. You can also see any overlapping templates whose configuration is superseded by the simulated template body or higher priority templates:
-
-```json
-{
-  "template" : {
-    "settings" : {
-      "index" : {
-        "number_of_shards" : "3"
-      }
-    },
-    "mappings" : {
-      "properties" : {
-        "@timestamp" : {
-          "type" : "date"
-        },
-        "ip_address" : {
-          "type" : "ip"
-        }
-      }
-    },
-    "aliases" : { }
-  },
-  "overlapping" : [
-    {
-      "name" : "daily_logs",
-      "index_patterns" : [
-        "logs-2020-01-*"
-      ]
-    }
-  ]

- We recommend installing OpenSearch on RHEL- or Debian-based Linux distributions that use [systemd](https://en.wikipedia.org/wiki/Systemd), such as CentOS, Amazon Linux 2, and Ubuntu (LTS). OpenSearch should work on many Linux distributions, but we only test a handful.
- The OpenSearch tarball ships with a compatible version of Java in the `jdk` directory. To find its version, run `./jdk/bin/java -version`. For example, the OpenSearch 1.0.0 tarball ships with Java 15 (non-LTS).

-
-  To use a different Java installation, set the `OPENSEARCH_JAVA_HOME` environment variable to the Java install location. We recommend Java 11 (LTS), but OpenSearch also works with Java 8.

 The OpenSearch logs include valuable information for monitoring cluster operations and troubleshooting issues. The location of the logs differs based on the installation type:

 - On Docker, OpenSearch writes most logs to the console and stores the remainder in `opensearch/logs/`. The tarball installation also uses `opensearch/logs/`.
- On most Linux installations, OpenSearch writes logs to `/var/log/opensearch/`.
+- On the RPM and Debian installations, OpenSearch writes logs to `/var/log/opensearch/`.

-Logs are available as `.log` (plain text) and `.json` files. Permissions for the OpenSearch logs are `-rw-r--r--` by default, meaning that any user account on the node can read them. You can change this behavior _for each log type_ in `log4j2.properties` using the `filePermissions` option. For example, you might add `appender.rolling.filePermissions = rw-r-----` to change permissions for the JSON server log. For details, see the [Log4j 2 documentation](https://logging.apache.org/log4j/2.x/manual/appenders.html#RollingFileAppender).

-# cat API
-
-You can get essential statistics about your cluster in an easy-to-understand, tabular format using the compact and aligned text (CAT) API. The cat API is a human-readable interface that returns plain text instead of traditional JSON.
-
-Using the cat API, you can answer questions like which node is the elected master, what state is the cluster in, how many documents are in each index, and so on.
-
-## Example
-
-To see the available operations in the cat API, use the following command:
-
-```
-GET _cat
-```
-
-## Common URL parameters
-
-You can use the following string parameters with your query.
-
-Parameter | Description
-:--- | :--- |
-`?v` |  Makes the output more verbose by adding headers to the columns. It also adds some formatting to help align each of the columns together. All examples in this section include the `v` parameter.
-`?help` | Lists the default and other available headers for a given operation.
-`?h`  |  Limits the output to specific headers.
-`?format` |  Outputs the result in JSON, YAML, or CBOR formats.
-`?sort` | Sorts the output by the specified columns.
-
-To see what each column represents, use the `?v` parameter:
-
-```
-GET _cat/<operation_name>?v
-```
-
-To see all the available headers, use the `?help` parameter:
-
-```
-GET _cat/<operation_name>?help
-```
-
-To limit the output to a subset of headers, use the `?h` parameter:
-
-```
-GET _cat/<operation_name>?h=<header_name_1>,<header_name_2>&v
-```
-
-Typically, for any operation you can find out what headers are available using the `?help` parameter, and then use the `?h` parameter to limit the output to only the headers that you care about.
-
-If you use the security plugin, make sure you have the appropriate permissions.

-# Cluster settings
-
-The cluster settings operation lets you check the current settings for your cluster, review default settings, and change settings. When you update a setting using the API, OpenSearch applies it to all nodes in the cluster.
-
-
-## Examples
-
-```json
-GET _cluster/settings?include_defaults=true
-```
-
-```json
-PUT _cluster/settings
-{
-  "persistent": {
-    "action": {
-      "auto_create_index": false
-    }
-  }
-}
-```
-

-## URL parameters
-
-All cluster settings parameters are optional.
-
-Parameter | Type | Description
-:--- | :--- | :---
-flat_settings | Boolean | Whether to return settings in the flat form, which can improve readability, especially for heavily nested settings. For example, the flat form of `"cluster": { "max_shards_per_node": 500 }` is `"cluster.max_shards_per_node": "500"`.
-include_defaults (GET only) | Boolean | Whether to include default settings as part of the response. This parameter is useful for identifying the names and current values of settings you want to update.
-master_timeout | Time | The amount of time to wait for a response from the master node. Default is 30 seconds.
-timeout (PUT only) | Time | The amount of time to wait for a response from the cluster. Default is 30 seconds.
-
-
-## Request body
-
-The GET operation has no request body options.
-
-For a PUT operation, the request body must contain `transient` or `persistent`, along with the setting you want to update:

-## Index naming restrictions
-
-OpenSearch indices have the following naming restrictions:
-
- All letters must be lowercase.
- Index names can't begin with underscores (`_`) or hyphens (`-`).
- Index names can't contain spaces, commas, or the following characters:
-
-  `:`, `"`, `*`, `+`, `/`, `\`, `|`, `?`, `#`, `>`, or `<`
-
-## URL parameters
-
-You can include the following URL parameters in your request. All parameters are optional.
-
-Parameter | Type | Description
-:--- | :--- | :---
-include_type_name | Boolean | If `true`, the request expects a type in the body of mappings. Because OpenSearch indices all have a type of `_doc`, we recommend that this parameter is left as the default of `false.`
-wait_for_active_shards | String | Specifies the number of active shards that must be available before OpenSearch processes the request. Default is 1 (only the primary shard). Set to `all` or a positive integer. Values greater than 1 require replicas. For example, if you specify a value of 3, the index must have two replicas distributed across two additional nodes for the request to succeed.
-master_timeout | Time | How long to wait for a connection to the master node. Default is `30s`.
-timeout | Time | How long to wait for the request to return. Default is `30s`.
-
-## Request body
-
-As part of your request, you can supply parameters in your request's body that specify index settings, mappings, and [aliases]({{site.url}}{{site.baseurl}}/opensearch/index-alias/) for your newly created index. The following sections provide more information about index settings and mappings.
-
-
-### Index settings
-
-Index settings are separated into two varieties: static index settings and dynamic index settings. Static index settings are settings that you specify at index creation and can't change later. You can change dynamic settings at any time, including at index creation.
-
-#### Static index settings
-
-Setting | Description
-:--- | :---
-index.number_of_shards | The number of primary shards in the index. Default is 1.
-index.number_of_routing_shards | The number of routing shards used to split an index.
-index.shard.check_on_startup | Whether the index's shards should be checked for corruption. Available options are `false` (do not check for corruption), `checksum` (check for physical corruption), and `true` (check for both physical and logical corruption). Default is `false`.
-index.codec | The compression type to use to compress stored data. Available values are `best_compression` and `default`.
-index.routing_partition_size | The number of shards a custom routing value can go to. Routing helps an imbalanced cluster by relocating values to a subset of shards rather than just a single shard. To enable, set this value to greater than 1 but less than `index.number_of_shards`. Default is 1.
-index.soft_deletes_enabled | Whether to retain a history of operations performed on the index.
-index.soft_deletes.retention_lease.period | The maximum amount of time to retain a shard's history of operations. Default is `12h`.
-index.load_fixed_bitset_filters_eagerly | Indicates whether cached filters should be pre-loaded for nested queries. Available options are `true` and `false`. Default is `true`.
-index.hidden | Whether the index should be hidden. Hidden indices are not returned as part of queries that have wildcards. Available options are `true` and `false`. Default is `false`.
-
-#### Dynamic index Settings
-
-Setting | Description
-:--- | :---
-index.number_of_replicas | The number of replica shards each primary shard should have. For example, if you have 4 primary shards and set `index.number_of_replicas` to 3, the index has 12 replica shards. Default is 1.
-index.auto_expand_replicas | Automatically expands the number of replicas based on the amount of data nodes in the cluster. Specify a lower bound and upper limit (for example, 0-9), or `all` for the upper limit. For example, if you have 5 data nodes and set `index.auto_expand_replicas` to 0-3, then the cluster does not autoamtically add another replica shard. However, if you set this value to `0-all` and add 2 more nodes for a total of 7, the cluster will expand to now have 6 replica shards. Default is disabled.
-index.search.idle.after | Amount of time a shard should wait for a search or get request until it goes idle. Default is `30s`.
-index.refresh_interval | How often the index should refresh, which publishes its most recent changes and makes them available for searching. Can be set to `-1` to disable refreshing. Default is `1s`.
-index.max_result_window | The maximum value of `from` + `size` for searches to the index. `from` is the starting index to search from, and `size` is the amount of results to return. Default: 10000.
-index.max_inner_result_window | The maximum value of `from` + `size` for inner hits definitions and top hits aggregations to the index. `from` is the starting index to search from, and `size` is the amount of top hits to return. Default is 100.
-index.max_rescore_window | The maximum value of `window_size` for rescore requests to the index. Rescore requests reorder the index's documents and return a new score, which can be more precise. Default is the same as index.max_inner_result_window or 10000 by default.
-index.max_docvalue_fields_search | Maximum amount of `docvalue_fields` allowed in a query. Default is 100.
-index.max_script_fields | Maximum amount of `script_fields` allowed in a query. Default is 32.
-index.max_ngram_diff | Maximum allowed difference between `min_gram` and `max_gram` values for `NGramTokenizer` and `NGramTokenFilter`. Default is 1.
-index.max_shingle_diff | Maximum allowed difference between `max_shingle_size` and `min_shingle_size` for the `shingle` token filter. Default is 3.
-index.max_refresh_listeners | Maximum amount of refresh listeners available on the index's shards.
-index.analyze.max_token_count | Maximum amount of tokens that can return from the `_analyze` API operation. Default is 10000.
-index.highlight.max_analyzed_offset | The maximum amount of characters that will be analyzed in a highlight request. Default is 1000000.
-index.max_terms_count | The maximum amount of terms that can be used in a terms query. Default is 65536.
-index.max_regex_length | The maximum character length of regex that can be in a regexp query. Default is 1000.
-index.query.default_field | A field or list of fields that OpenSearch uses in queries in case a field isn't specified in the parameters.
-index.routing.allocation.enable | Specifies options for the index's shard allocation. Available options are `all` (allow shard allocation for all shards), `primaries` (allow shard allocation only for primary shards), `new_primaries` (allow shard allocaiton only for new primary shards), and `none` (do not allow shard allocation). Default is `all`.
-index.routing.rebalance.enable | Enables shard rebalancing for the index. Available options are `all` (allow shard rebalancing for all shards), `primaries`, (allow shard rebalancing only for primary shards), `replicas` (allow shard rebalancing only for replicas), and `none` (do not allow shard rebalancing). Default is `all`.
-index.gc_deletes | Amount of time to retain a deleted document's version number. Default is `60s`.
-index.default_pipeline | The default ingest node pipeline for the index. If the default pipeline is set and the pipeline does not exist, then index requests fail. The pipeline name `_none` specifies that the index does not have an ingest pipeline.
-index.final_pipeline | The final ingest node pipeline for the index. If the final pipeline is set and the pipeline does not exist, then index requests fail. The pipeline name `_none` specifies that the index does not have an ingest pipeline.
-
-### Mappings
-
-Mappings define how a documents and its fields are stored and indexed. If you're just starting to build out your cluster and data, you may not know exactly how your data should be stored. In those cases, you can use dynamic mappings, which tell OpenSearch to dynamically add data and their fields. However, if you know exactly what types your data fall under and want to enforce that standard, then you can use explicit mappings.
-
-For example, if you want to indicate that `year` should be of type `text` instead of an `integer`, and `age` should be an `integer`, you can do so with explicit mappings. Using dynamic mapping, OpenSearch might interpret both `year` and `age` as integers.
-
-#### Dynamic mapping types
-
-Type | Description
-:--- | :---
-null | A `null` field can't be indexed or searched. When a field is set to null, OpenSearch behaves as if that field has no values.
-boolean | OpenSearch accepts `true` and `false` as boolean values. An empty string is equal to `false.`
-float | A single-precision 32-bit floating point number.
-double | A double-precision 64-bit floating point number.
-integer | A signed 32-bit number.
-object | Objects are standard JSON objects, which can have fields and mappings of their own. For example, a `movies` object can have additional properties such as `title`, `year`, and `director`.
-array | Arrays in OpenSearch can only store values of one type, such as an array of just integers or strings. Empty arrays are treated as though they are fields with no values.
-text | A string sequence of characters that represent full-text values.
-keyword | A string sequence of structured characters, such as an email or ZIP code.
-date detection string | Enabled by default, if new string fields match a date's format, then the string is processed as a `date` field. For example, `date: "2012/03/11"` is processed as a date.
-numeric detection string | If disabled, OpenSearch may automatically process numeric values as strings when they should be processed as numbers. When enabled, OpenSearch can process strings into `long`, `integer`, `short`, `byte`, `double`, `float`, `half_float`, `scaled_float`, `unsigned_long`. Default is disabled.
-
-#### Explicit mapping
-
-If you know exactly what your data's typings need to be, you can specify them in your request body when creating your index.
-
-```json
-{
-  "mappings": {
-    "properties": {
-      "year":    { "type" : "text" },

-preference | string | Specifies a preference of which shard to retrieve results from. Available options are `_local`, which tells the operation to retrieve results from a locally allocated shard replica, and a custom string value assigned to a specific shard replica. By default, OpenSearch executes get document operations on random shards.
-realtime | boolean | Specifies whether the operation should run in realtime. If false, the operation waits for the index to refresh to analyze the source to retrieve data, which makes the operation near-realtime. Default is true.
-refresh | boolean | If true, OpenSearch refreshes shards to make the operation visible to searching. Default is false.
-routing | string | A value used to route the operation to a specific shard.
-stored_fields | boolean | If true, the operation retrieves document fields stored in the index rather than the document's `_source`. Default is false.

-# Scroll
-
-You can use the `scroll` operation to retrieve a large number of results. For example, for machine learning jobs, you can request an unlimited number of results in batches.
-
-To use the `scroll` operation, add a `scroll` parameter to the request header with a search context to tell OpenSearch how long you need to keep scrolling. This search context needs to be long enough to process a single batch of results.
-
-Because search contexts consume a lot of memory, we suggest you don't use the `scroll` operation for frequent user queries. Instead, use the `sort` parameter with the `search_after` parameter to scroll responses for user queries.
-{: .note }
-
-## Example
-
-To set the number of results that you want returned for each batch, use the `size` parameter:
-
-```json
-GET shakespeare/_search?scroll=10m
-{
-  "size": 10000
-}
-```
-
-OpenSearch caches the results and returns a scroll ID to access them in batches:
-
-```json
-"_scroll_id" : "DXF1ZXJ5QW5kRmV0Y2gBAAAAAAAAAAUWdmpUZDhnRFBUcWFtV21nMmFwUGJEQQ=="
-```
-
-Pass this scroll ID to the `scroll` operation to get back the next batch of results:
-
-```json
-GET _search/scroll
-{

-
-Using this scroll ID, you get results in batches of 10,000 as long as the search context is still open. Typically, the scroll ID does not change between requests, but it *can* change, so make sure to always use the latest scroll ID. If you don't send the next scroll request within the set search context, the `scroll` operation does not return any results.
-
-If you expect billions of results, use a sliced scroll. Slicing allows you to perform multiple scroll operations for the same request, but in parallel.
-Set the ID and the maximum number of slices for the scroll:
-
-```json
-GET shakespeare/_search?scroll=10m
-{
-  "slice": {
-    "id": 0,
-    "max": 10
-  },
-  "query": {
-    "match_all": {}
-  }
-}
-```
-
-With a single scroll ID, you get back 10 results.
-You can have up to 10 IDs.
-
-Close the search context when you’re done scrolling, because the `scroll` operation continues to consume computing resources until the timeout:
-
-```json
-DELETE _search/scroll/DXF1ZXJ5QW5kRmV0Y2gBAAAAAAAAAAcWdmpUZDhnRFBUcWFtV21nMmFwUGJEQQ==
-```
-
-To close all open scroll contexts:
-
-```json
-DELETE _search/scroll/_all
-```
-
-The `scroll` operation corresponds to a specific timestamp. It doesn't consider documents added after that timestamp as potential results.
-
-
-## Path and HTTP methods
-
-```
-GET _search/scroll
-POST _search/scroll
-```
-```
-GET _search/scroll/<scroll-id>
-POST _search/scroll/<scroll-id>
-```
-
-## URL parameters
-
-All scroll parameters are optional.
-
-Parameter | Type | Description
-:--- | :--- | :---
-scroll | Time | Specifies the amount of time the search context is maintained.
-scroll_id | String | The scroll ID for the search.
-rest_total_hits_as_int | Boolean | Whether the `hits.total` property is returned as an integer or an object. Default is false.

 A task is any operation you run in a cluster. For example, searching your data collection of books for a title or author name is a task. When you run OpenSearch, a task is automatically created to monitor your cluster's health and performance. For more information about all of the tasks currently executing in your cluster, you can use the `tasks` API operation.

-# Upgrade from Kibana OSS to OpenSearch Dashboards
-
-Kibana OSS stores its visualizations and dashboards in one or more indices (`.kibana*`) on the Elasticsearch OSS cluster. As such, the most important step is to leave those indices intact as you upgrade from Elasticsearch OSS to OpenSearch.
-
-Consider exporting all Kibana objects prior to starting the upgrade. In Kibana, choose **Stack Management**, **Saved Objects**, **Export objects**.
-{: .tip }
-
-1. After you upgrade your Elasticsearch OSS cluster to OpenSearch, stop Kibana.
-
-1. For safety, make a backup copy of `<kibana-dir>/config/kibana.yml`.
-
-1. Extract the OpenSearch Dashboards tarball to a new directory.
-
-1. Port your settings from `<kibana-dir>/config/kibana.yml` to `<dashboards-dir>/config/opensearch_dashboards.yml`.
-
-   In general, settings with `elasticsearch` in their names map to `opensearch` (e.g. `elasticsearch.shardTimeout` and `opensearch.shardTimeout`) and settings with `kibana` in their names map to `opensearchDashboards` (e.g. `kibana.defaultAppId` and `opensearchDashboards.defaultAppId`). Most other settings use the same names.
-
-   For a full list of OpenSearch Dashboards settings, see [here](https://github.com/opensearch-project/OpenSearch-Dashboards/blob/main/config/opensearch_dashboards.yml){:target='\_blank'}.
-
-1. If your OpenSearch cluster uses the security plugin, preserve and modify the default settings in `opensearch_dashboards.yml`, particularly `opensearch.username` and `opensearch.password`.
-
-   If you disabled the security plugin on your OpenSearch cluster, remove or comment out all `opensearch_security` settings. Then run `rm -rf plugins/security-dashboards/` to remove the security plugin.
-
-1. Start OpenSearch Dashboards:
-
-   ```
-   ./bin/opensearch-dashboards
-   ```
-
-1. Log in, and verify that your saved searches, visualizations, and dashboards are present.

-# About the process
-
-The process of upgrading from Elasticsearch OSS (including Open Distro for Elasticsearch) to OpenSearch varies depending on your current version of Elasticsearch OSS, install type, tolerance for downtime, and cost-sensitivity. Rather than concrete steps to cover every situation, we have general guidance for the process.
-
-Three approaches exist:
-
- Use a snapshot to [migrate your Elasticsearch OSS data]({{site.url}}{{site.baseurl}}/upgrade-to/snapshot-migrate/) to a new OpenSearch cluster.
- Perform a [rolling upgrade or cluster restart upgrade]({{site.url}}{{site.baseurl}}/upgrade-to/upgrade-to/) on your existing nodes.
- Replace existing Elasticsearch OSS nodes with new OpenSearch nodes. Node replacement is most popular when upgrading [Docker clusters]({{site.url}}{{site.baseurl}}/upgrade-to/docker-upgrade-to/).
-
-Regardless of your approach, to safeguard against data loss, we recommend that you take a [snapshot]({{site.url}}{{site.baseurl}}/opensearch/snapshot-restore/) of all indices prior to any migration.
-
-If your existing clients include a version check, such as recent versions of Logstash OSS and Filebeat OSS, [check compatibility]({{site.url}}{{site.baseurl}}/clients/agents-and-ingestion-tools/index/) before upgrading.
