Additional Information:-I get the New Monitor Resource Window on the host where the cluster is active, but not on the host where the Service Group is active.
On hosts where the Cluster Service and Service (Resource) Group reside on the same node I am able to add a profile for cdm monitoring (for example) under the Service Group. However, when the Service Group is on a different node to the Cluster Service I am unable to monitor clustered filesystems (for example).
I have done this now, but it has not resolved the issue unfortunately. I still get the same error.
