If you want Heartbeat to connect to a cluster that has X-Pack security enabled, there are extra configuration steps:
To send data to a secured cluster through the
elasticsearchoutput, Heartbeat 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.
To search the indexed Heartbeat data and visualize it in Kibana, users need access to the indices Heartbeat creates.
If encryption is enabled on the cluster, you need to enable HTTPS in the Heartbeat configuration.
Heartbeat uses the
beats_systemuser to send monitoring data to Elasticsearch. If you plan to monitor Heartbeat in Kibana and have not yet set up the password, set it up now.
