+=== Monitoring {es} with {metricbeat}
+
+beta[] In 6.5 and later, you can use {metricbeat} to collect data about {es} 
+and ship it to the monitoring cluster, rather than routing it through exporters 
+as described in <<configuring-monitoring>>. 
+
+image::monitoring/images/metricbeat.png[Example monitoring architecture]
+
+To learn about monitoring in general, see 
+{stack-ov}/xpack-monitoring.html[Monitoring the {stack}]. 
+
+. Enable the collection of monitoring data. Set 
+`xpack.monitoring.collection.enabled` to `true` on the production cluster. +
++ 
+--
+For example, you can use the following APIs to review and change this setting:
+
+[source,js]
+----------------------------------
+GET _cluster/settings
+
+PUT _cluster/settings
+{
+  "persistent": {
+    "xpack.monitoring.collection.enabled": true
+  }
+}
+----------------------------------
+// CONSOLE
+
+For more information, see <<monitoring-settings>> and <<cluster-update-settings>>.
+--
+
+. Disable the default collection of {es} monitoring metrics. Set 
+`xpack.monitoring.elasticsearch.collection.enabled` to `false` on the production 
+cluster. +
++ 
+--
+For example, you can use the following API to change this setting:
+
+[source,js]
+----------------------------------
+PUT _cluster/settings
+{
+  "persistent": {
+    "xpack.monitoring.elasticsearch.collection.enabled": false
+  }
+}
+----------------------------------
+// CONSOLE
+
+Leave `xpack.monitoring.enabled` set to its default value (`true`). 
+--
+
+. On each {es} node in the production cluster:
+
+.. {metricbeat-ref}/metricbeat-installation.html[Install {metricbeat}].
+
+.. Enable the {es} module in {metricbeat}. +
++
+--
+For example, to enable the default configuration in the `modules.d` directory, 
+run the following command:
+
+["source","sh",subs="attributes,callouts"]
+----------------------------------------------------------------------
+metricbeat modules enable elasticsearch

+For more information, see 
+{metricbeat-ref}/configuration-metricbeat.html[Specify which modules to run] and 
+{metricbeat-ref}/metricbeat-module-elasticsearch.html[{es} module]. 
+--
+
+.. Configure the {es} module in {metricbeat}. +
++
+--
+You must specify the following settings in the `modules.d/elasticsearch.yml` file:
+
+[source,yaml]
+----------------------------------
+- module: elasticsearch
+  metricsets:
+    - ccr
+    - cluster_stats
+    - index
+    - index_recovery
+    - index_summary
+    - ml_job
+    - node_stats
+    - shard
+  period: 10s
+  hosts: ["http://localhost:9200"] <1>
+  xpack.enabled: true
+----------------------------------
+<1> This setting identifies the host and port number that are used to access {es}.  
+--
+
+.. If {security} is enabled, you must also provide a user ID and password so that 
+{metricbeat} can collect metrics successfully. 
+
+... Create or identify a user that you want to use to collect the metrics. 
++
+--
+TIP: There is a `remote_monitoring_user` built-in user that grants the privileges 
+necessary for {metricbeat} to monitor {stack} products. See 
+{stack-ov}/built-in-users.html[Built-in users].
+
+Alternatively, you can choose a different user and give them the 
+`remote_monitoring_collector` {stack-ov}/built-in-roles.html[built-in role]. 
+--
+
+... Add the `username` and `password` settings to the {es} module configuration 
+file.
++
+--
+For example, add the following settings in the `modules.d/kibana.yml` file:
+
+[source,yaml]
+----------------------------------
+- module: elasticsearch
+  ...
+  username: remote_monitoring_user
+  password: YOUR_PASSWORD
+----------------------------------
+--
+
+.. If you configured {es} to use <<configuring-tls,encrypted communications>>, 
+you must access it via HTTPS. For example, use a `hosts` setting like 
+`https://localhost:9200` in the `modules.d/elasticsearch.yml` file.
+
+.. Identify where to send the monitoring data. +
++
+--
+TIP: In production environments, we strongly recommend using a separate cluster 
+(referred to as the _monitoring cluster_) to store the data. Using a separate 
+monitoring cluster prevents production cluster outages from impacting your 
+ability to access your monitoring data. It also prevents monitoring activities 
+from impacting the performance of your production cluster.
+
+For example, specify the {es} output information in the {metricbeat} 
+configuration file (`metricbeat.yml`):
+
+[source,yaml]
+----------------------------------
+output.elasticsearch:
+  hosts: ["http://es-mon-1:9200", "http://es-mon2:9200"] <1>
+----------------------------------
+<1> In this example, the data is stored on a monitoring cluster with nodes 
+`es-mon-1` and `es-mon-2`. 
+
+For more information about these configuration options, see 
+{metricbeat-ref}/elasticsearch-output.html[Configure the {es} output].
+--
+
+.. If {security} is enabled on the monitoring cluster, you must provide a valid 
+user ID and password so that {metricbeat} can send metrics successfully. 
+
+... Create or identify a user that you want to use to send the metrics. 
++
+--
+TIP: There is a `remote_monitoring_user` built-in user that grants the privileges 
+necessary for {metricbeat} to monitor {stack} products. See 
+{stack-ov}/built-in-users.html[Built-in users].
+
+Alternatively, you can choose a different user and give them the 
+`remote_monitoring_agent` {stack-ov}/built-in-roles.html[built-in role]. 
+--
+
+... Add the `username` and `password` settings to the {es} output information in 
+the {metricbeat} configuration file (`metricbeat.yml`):
++
+--
+[source,yaml]
+----------------------------------
+output.elasticsearch:
+  ...
+  username: remote_monitoring_user
+  password: YOUR_PASSWORD
+----------------------------------
+--
+
+.. If you configured the monitoring cluster to use 
+<<configuring-tls,encrypted communications>>, you must access it via 
+HTTPS. For example, use a `hosts` setting like `https://es-mon-1:9200` in the 
+`metricbeat.yml` file.
