Active Check Not Working

[jasonw]

I have a check on a Windows Server 2012 host in a template defined as:

perf_counter["\LogicalDisk({#FSNAME})\Avg. Disk sec/Read"]

And it seems to be working fine... So, I CLONED this check, changed the title and the counter to this:

perf_counter["\LogicalDisk({#FSNAME})\Avg. Disk sec/Write"]

(Note WRITE instead of READ)... For whatever reason, the agent never picks up the check... I even tried to re-write it as:

perf_counter[\236({#FSNAME})\210]

I've even stopped and restarted the agent, and looked at the debug output:

Notice that it never receives the check. What is going on here?

In case it makes a difference, this is a check defined as an Item Prototype on a Mounted Filesystem Discovery rule...
