Creating & Editing performance counters in a powershell script or command line
Figured this out a while ago, but never posted.
Here's my solution:
//save out the type name for sanity's sake$ccdTypeName = 'System.Diagnostics.CounterCreationData'$CounterCollection = New-Object System.Diagnostics.CounterCreationDataCollection//create as many counters as we'd like, and add them to the collection. here's just one:$CounterCollection.Add( (New-Object $ccdTypeName "Counter Name", "Counter Description", NumberOfItems32) )//create the category with the counter collection[System.Diagnostics.PerformanceCounterCategory]::Create($perfCounterCategoryName, $perfCounterVersion, [Diagnostics.PerformanceCounterCategoryType]::SingleInstance, $CounterCollection);
