Use this option to specify the time period for which VWService-wide statistics are collected and written to the database. The interval you set applies to all isolated regions in the VWService. For more information about how Process Engine (PE) manages statistics, see About workflow statistics.
To configure statistics collection
You must restart the PE software on all PE servers to make the changes take effect. Use Process Task Manager to restart the software.
For information on enabling statistics see Enable or disable statistics collection.
