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 collection level 1.

To configure statistics settings, the vSphere Client must be connected to a vCenter Server system.


Not all attributes are configurable for each collection interval.


Select Administration > vCenter Server Settings.


If your environment uses multiple vCenter Servers, in Current vCenter Server, select the server.


In the navigation panel, select Statistics.


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 levels, statistical data is not archived in the vCenter Server database.


(Optional) To change a collection interval attribute, select its row in the Statistics Interval section and click Edit to open the Edit Collection Interval dialog box.


In Keep Samples for, select an archive length.

This option is configurable only for the Day and Year intervals.


In Statistics Interval, select an interval duration.

This option is configurable only for the Day interval.


In Statistics Level select a new level interval level.

Level 4 uses the highest number of statistics counters. Use it only for debugging purposes.

The statistics level must be less than or equal to the statistics level set for the preceeding statistics interval. This is a vCenter Server dependency.


(Optional) In the Database Size section, estimate the effect of the statistics settings on the database.


Enter the number of Physical Hosts.


Enter the number of Virtual Machines.

The estimated space required and number of database rows required are calculated and displayed.


If necessary, make changes to your statistics collection settings.


Click OK.
