ESXi Server Performance Intervals

An ESXi server collects performance data for each performance counter every 20 seconds. The PerformanceManager.historicalInterval array for an ESXi Server contains a single, readonly PerfInterval object that specifies rollup data collection every 5 minutes. You cannot retrieve 5-minute rollup data from an ESXi Server directly. You can use a vCenter Server connection to obtain 5-minute rollup data for an ESXi Server. The following table shows the historical interval property values on an ESXi server. You cannot modify this performance interval.

Property	Value	Description
key	1	Numeric identifier for the PerfInterval.
name	PastDay	Name of the PerfInterval.
samplingPeriod	300	Time interval between data sampling events.
length	129600	Number of seconds that statistics associated with the interval are kept by the vCenter Server.
enabled	true	This PerfInterval is enabled on the system.
level	null	Statistics collection level. For an ESXi system, this property is null. The PerfInterval object on an ESXi system defines the baseline interval.
