BloombergLP::balb::PerformanceMonitor::Measure

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.
