Configure authentication credentials.

To send data to a secured cluster through the elasticsearch output, Metricbeat 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 Metricbeat indices.

To search the indexed Metricbeat data and visualize it in Kibana, users need access to the indices Metricbeat creates.

Configure Metricbeat to use encrypted connections.

If encryption is enabled on the cluster, you need to enable HTTPS in the Metricbeat configuration.

Set the password for the built-in monitoring user.

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