Title: discovery: Fix missing datasource error for cluster hosts Class: fix Compatible: compat Component: checks Date: 1696495573 Edition: cre Knowledge: doc Level: 1 State: unknown Version: 2.3.0b1 Previously, a missing datasource error would be shown in a discovery page of a cluster host if the cluster host had 'No IP' configured but had nodes with an agent datasource. Services of a cluster host would also become vanished. Checkmk now supports the described setup, there is no error in the discovery page and clustered services are discovered.
