Well, a fair amount of time has passed since this post was created.
This is indeed becoming an issue.
There seems to be a whole bunch of perfmon counters etc that have been renamed, additional services etc.
The Exchange 2010 monitoring sets do not just "plug in" to an Exchange 2013 machine. There's a lot that just does not fit.
It has been stated by LabTech support that an update later in the year, probably the 2014 release will contain the necessary monitoring sets, but hey thats too late for us.
It seems we are going to have manually rebuild a new set.
if we want to fill this gaping hole in monitoring.
Has anyone else done anything yet?
