Configure Statistics Collection Intervals in the vSphere Web Client
Statistic collection intervals determine the frequency at which statistic queries occur, the length of time
statistical data is stored in the database, and the type of statistical data that is collected. You can view the
collected statistics through the performance charts in the vSphere Web Client or through command-line
monitoring utilities.
Note Not all interval attributes are configurable.
Prerequisites
Required privilege: Performance.ModifyIntervals
Procedure
1 In the vSphere Client, navigate to the vCenter Server instance.
2 Select the Configure tab.
3 Under Settings, select General.
4 Click Edit.
5 From Statistics intervals, click a statistics interval attribute to edit its value.
a In Interval duration, select the time interval in which statistics data is collected.
b In Save for, select for how long the archived statistics are kept in the database.
c In Statistics level, select a new level for collecting statistics.
The lower the level is, the fewer number of statistic counters are used. Level 4 uses all statistics
counters. Use it only for debugging purposes.
The statistics level must be less than or equal to the statistics level that is set for the preceding
statistics interval. This is a vCenter Server dependency.
6 (Optional) In Database Size, estimate the effect of the statistics settings on the database.
a Enter the number of Physical Hosts.
b Enter the number of Virtual Machines.
The estimated space required and number of database rows required are calculated and
displayed.
c If necessary, make changes to your statistics collection settings.
7 Click OK.
