3.1.1.3 Counters
Each performance counter in a counterset is identified by a numeric ID; a counter can be uniquely identified on the system by using the counterset GUID, counterset instance name or ID, and counter ID. Each performance counter can have a localized name and description, type, and detail level among other metadata fields. Depending on the type of performance counter, it can be necessary to use the value of other performance counters to calculate the value.
