These diagnostic alerts indicate when a node leaves the cluster, and when a node joins the cluster. 

The following appears in the application log:

INFO ; HAZELCAST ; HAZELCAST-1001 ; Node joined the cluster ; not-detected ;  ;  ; {"member":"Member [...]:... - ..."}
WARNING ; HAZELCAST ; HAZELCAST-1002 ; Node left the cluster ; not-detected ;  ;  ; {"member":"Member [...]:... - ..."}

These alerts are enabled by default in Confluence 6.11 or later.
