To set up how statistical data is recorded, you configure statistics intervals.

Statistic 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 collected.

Enabling a statistics interval increases the number of statistics stored in the vCenter Server database. Disabling a statistics interval disables all subsequent intervals and decreases the number of statistics stored in the vCenter Server database.

The impact of the statistics collection on your vCenter database is based on the current vCenter and inventory size.
