We've noticed a possible issue with local space monitoring. A server RAID controller went off-line(failed), the array disappeared, and we didn't get a notification of a disk space fault. Which is probably normal as the drive letter never hit our free space threshold.
I was thinking of setting up a rule to monitor many drives and have it fall under 1 event. But performance counters seem to be based entirely on performance, and not appearance.
Is there some place else where we can monitor local storage that turn up MIA?
