:mrdocs:

Enumerates the set of performance measures this class is capable of monitoring. Note that CPU utilization measures are calculated as a ratio of CPU time to elapsed time between two consecutive calls to `collect`, and therefore no value will be available if `collect` has been called only once. Note that not all measures are supported on all platforms; for an unsupported measure, the behavior is as if the system reports a zero value.
