Configure APM Server to use X-Pack security

If you want APM Server to connect to a cluster that has X-Pack security enabled, there are extra configuration steps:

Configure authentication credentials.

To send data to a secured cluster through the elasticsearch output, APM Server needs to authenticate as a user who can manage index templates, monitor the cluster, create indices, and read and write to the indices it creates.
Grant users access to APM Server indices.

To search the indexed APM Server data and visualize it in Kibana, users need access to the indices APM Server creates.
Configure APM Server to use encrypted connections.

If encryption is enabled on the cluster, you need to enable HTTPS in the APM Server configuration.
Set the password for the built-in monitoring user.

APM Server uses the apm_system user to send monitoring data to Elasticsearch. If you plan to monitor APM Server in Kibana and have not yet set up the password, set it up now.
