The
PerformanceManager provides the
UpdateCounterLevelMapping method
to change the collection level for individual performance counters (PerfCounterInfo.level).
Consider carefully the performance and storage consequences of using the
UpdateCounterLevelMapping method.
If you use this method, you may cause a significant increase in data collection
and storage, along with a corresponding decrease in performance. vCenter Server
performance and database storage requirements depend on the collection levels
defined for the performance intervals (PerformanceManager.historicalInterval) and the
collection levels specified for individual performance counters
(PerfCounterInfo.level).
