How to select a performance counter with Get-Counter with * in name

Question

When I try to select a counter of which I know the name and the fact that is exists, like for example Get-Counter -ListSet '\ProcessorPerformance(*)\frequency' | Select-Object -ExpandProperty Counter, I get the error that:

Get-Counter : Cannot find any performance counter sets on the localhost computer that match the following: \ProcessorPerformance(*)\frequency. At line:1 char:1

How can I get a counter when I know the full name or path?

Answer 1

maybe you can find help on the scripting guy site :

(Get-Counter -ListSet 'processor information').paths  | get-counter

Answer 2

You're mixing sets and counters. The counter 'Processor Frequency' is contained within the set named 'Processor Information'. Your example is asking for a set named '\ProcessorPerformance(*)\frequency', which does not exist.

A brief example:

# Get the set for Processor Information.
$set = Get-Counter -ListSet 'Processor Information'
# List available counters in set.
$set.Counter

# Alternatively, get just the specific counter.
Get-Counter -Counter '\Processor Information(*)\Processor Frequency'
