It works fine for "standard" performance counters, but it does not work for counters with an * in them. Example \\Server\MSExchangeIS Store(*)\RPC Average Latency.
The problem is that "\\Server\MSExchangeIS Store(*)\RPC Average Latency" is not actually a counter that exists on the server, it is a list set of counters. When you add that counter in perfmon, it adds one counter for each store on the server.
I can expand the list set via Get-Counter -ListSet "MSExchange IS Store", then find the actual counter I want in the output and put that into the script, but I would like to get it working by just putting "MSExchangeIS Store(*)\RPC Average Latency" into the script and getting output for each Store on the server.
Does that make sense?
Anyone have any ideas on how I can get that working?
It looks lke Import-Counter also has a -ListSet parameter. Your script could run that command against the blg files, then compare your $Counter parameter (using wildcards to the list) before running Import-Counter again with the matching values. Something like this, though I haven't tested it:
