-== Monitoring Kibana

+++++
 
-See
-{kibana-ref}/monitoring-xpack-kibana.html[Monitoring {kib}]. 
+If you enable the collection of monitoring data in your cluster, you can 
+optionally collect metrics about {kib}. 
+
+The following method involves sending the metrics to {es}, which ultimately 
+routes them to the monitoring cluster. For an alternative method, see 
+<<monitoring-metricbeat>>. 
+
+To learn about monitoring in general, see 
+{stack-ov}/xpack-monitoring.html[Monitoring the {stack}]. 
+
+. Enable the collection of monitoring data in the {stack}. 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
+  }
+}
+----------------------------------
+
+For more information, see {ref}/monitoring-settings.html[Monitoring settings in {es}] 
+and {ref}/cluster-update-settings.html[Cluster update settings].
+--
+
+. Verify that `xpack.monitoring.enabled` and
+`xpack.monitoring.kibana.collection.enabled` are set to `true` in the 
+`kibana.yml` file on your production cluster. These are the default values. For 
+more information, see <<monitoring-settings-kb,Monitoring settings in {kib}>>.
+
+. Identify where to send monitoring data. {kib} automatically
+sends metrics to the {es} cluster specified in the `elasticsearch.url` setting
+in the `kibana.yml` file. This property has a default value of
+`http://localhost:9200`. +
++
+--
+[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. 
+
+If {security} is enabled on the production cluster, use an HTTPS URL such
+as `https://<your_production_cluster>:9200` in this setting.
+===============================
+
+--
+
+. If {security} is enabled on the production cluster:
+
+.. Verify that there is a
+valid user ID and password in the `elasticsearch.username` and
+`elasticsearch.password` settings in the `kibana.yml` file. These values are
+used when {kib} sends monitoring data to the production cluster.
+
+.. Configure {kib} to encrypt communications between the {kib} server and the
+production cluster. This set up involves generating a server certificate and
+setting `server.ssl.*` and `elasticsearch.ssl.certificateAuthorities` settings
+in the `kibana.yml` file on the {kib} server. For example:
++
+--
+[source,yaml]
+--------------------------------------------------------------------------------
+server.ssl.key: /path/to/your/server.key
+server.ssl.certificate: /path/to/your/server.crt
+--------------------------------------------------------------------------------
+
+If you are using your own certificate authority to sign certificates, specify
+the location of the PEM file in the `kibana.yml` file:
+
+[source,yaml]
+--------------------------------------------------------------------------------
+elasticsearch.ssl.certificateAuthorities: /path/to/your/cacert.pem
+--------------------------------------------------------------------------------
+
+For more information, see <<using-kibana-with-security>>.
+--
+
+. Restart {kib}.
