On my Win2008 R2 clusters there is a performance counter called Cluster Multicast Request-Response Messages\Messages Outstanding.
Solarwinds includes it as a monitor on their Failover Clustering application template. One of my Hyper-V nodes keeps having this alarm go off (value greater than 0). I'm willing to remove this counter from the monitor but want to understand what it means first.

There is a Failover Clustering Performance Counters blog post on MSDN that describes the different Performance counters that are available.
