If you want Functionbeat to connect to a cluster that has X-Pack security enabled, there are extra configuration steps:
You can use role-based access control to grant Functionbeat users access to secured resources.
To interact with a secured cluster, Functionbeat must either provide basic authentication credentials or present a client certificate.
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.
