If you want Functionbeat 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, Functionbeat 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 Functionbeat data and visualize it in Kibana, users need access to the indices Functionbeat creates.
If encryption is enabled on the cluster, you need to enable HTTPS in the Functionbeat configuration.
Functionbeat uses the
beats_systemuser to send monitoring data to Elasticsearch. If you plan to monitor Functionbeat in Kibana and have not yet set up the password, set it up now.
