Public Function CreateCounterSetInstance (instanceName As String) As CounterSetInstance

Parameters

instanceName
String String String String

Name of the instance. The name must be unique.

Remarks

Call this method one time for single-instance counter sets and one or more times for multiple-instance counter sets.

The provider determines when it creates an instance. If the counter data is more static, the provider can create an instance at initialization time. For example, the number of processors on a computer would be considered static, so a provider that provides counter data for processors could create an instance for each processor on the computer at initialization time. For counters that are more dynamic, such as disk or process counters, the providers would create the new instances in response to a new USB device being added or a new process being created.

The provider should keep the counter data up-to-date at all times.
