I setup a Windows/SQL 2008 cluster and have Nagios all setup. The problem is that the disks and services on the passive node show critical or unknown because they are not there or stopped. I am looking for a way to monitor the disks and services from a cluster level so I don't have anything showing down.

I found the following URL but I don't see anything about services. I also tried setting it up and was unsuccessful.

You should configure the nagios to probe the sqlcluster IP only and depending on whether you have three instances of the nagios agent.
One runs on the each node
And one that is part of the cluster resource binds to the cluster IP
This way you can monitor each node individually and then you check the clustered instance for the cluster related resources.
I'd think you want to know when the passive node is down.

OK that makes sense, I created another host with the cluster resources and removed them from the nodes but am still monitoring other things on the nodes.

Another question you might know, it would be cool to have Nagios check to see what the active node is. So like some check on the cluster to check for the hostname, and if the hostname does not equal node 1 (primary) then it goes critical. I figure since I want it on node 1 most of the time that it would be nice to know if it fails over for some reason.

You would run a check on the hostname=yourpreferred node.
Within the nagios script you have on the Windows server a check for name that will ouput the %COMPUTERNAME%

Alternatively, You could configure the cluster such that node 1 is primary which will result in failback when the primary node comes back.
