Cluster Service Monitoring

Below are the participating hosts having DNS name resolution
MSWINCLU.abc.com - cluster
CLUNODE1.abc.com - active node running an active database instance
CLUNODE1.abc.com- passive node

Created New rule: Clustered services, → selected Explicit hosts → on service → {entered different cluster service names like SQL*.*, SRVAPI}

Performed fresh services discovery on all nodes and cluster, but we are unable to discover any new services either on cluster or on nodes please help
Untitled

also wanted to know, can we monitor any cluster services or only monitor which are mentioned on services → catalog of checkmk pluins, as we are not using MSSQL

we also tried with MSSQL services, but those also not working @andreas-doehler
