My current solution for this is pretty messy, but it works for me.
In the below I am assuming that you are going to have the windows bb client installed on all nodes of the cluster.
Active/Passive: Since want to know when the services fail over I check to ensure processes/services are running on the active node, as well as ensuring that the cluster service is running on both nodes. This let's me know when it fails over so I can investigate immediately.
I also run a specific application check against the clustered application on the cluster address to ensure the application itself is up and running. If it isn't then there is a really serious problem.
Active/Active: Since I don't do this I can be entirely sure, but this would be easier to monitor I would think, just ensure that all the services required are running on all nodes, including the cluster service itself.
I hope this is of some help.

Hello All,
Our new director would like to monitor EVERYTHING from BB/Hobbit. We have been monitoring our UNIX and Storage Devices for a few years now. Now that I have windows servers to monitor, I'd like to know if anyone has a decent way to monitor Windows Clusters? I had a thought to monitor by ping each node in the cluster, and the cluster name, ie:
Nodea - Application Offline Nodeb - Application Online Clustername - Application Responding @ This address
How would you set up resource (process) monitoring for an Active / Passive cluster? Or an Active / Active cluster?
This is in response to a problem that has been occurring on a new 24x7 Windows server blue screening daily, in spite of all the "fixes" that have occurred to solve the problem (more hardware, patches, reload os, etc, etc).
We'll soon be moving the application to an AIX server, but I'll have the same questions on an HACMP cluster at that point :)
TIA
