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

).
