When a folder was configured to monitor its hosts via a Checkmk Relay, a host or subfolder that overrode the Monitored on relay attribute to No relay was still treated as a relay host. Running a service discovery on such a host failed with:
[agent]: This data source is not supported for relay hosts.
The override is now respected: a host or subfolder explicitly set to No relay is no longer monitored via the relay, and its agent and other data sources work as expected. This also applies when the No relay setting is inherited from a subfolder that overrides a relay set on a parent folder.
