You can change the frequency at which statistic queries occur, the length of time statistical data is stored in the vCenter Server database, and the amount of statistical data collected. By default, all collection intervals are enabled and query for statistics at statistics level 1.

To configure statistics settings, verify that the vSphere Client is connected to a vCenter Server system.

Note

Not all attributes are configurable for each collection interval.

3

In the navigation panel, select Statistics.

4

In the Statistics Intervals section, select or deselect a collection interval to enable or disable it.

Enabling a longer interval automatically enables all shorter intervals. If you disable all collection intervals, statistical data is not archived in the vCenter Server database.
