Group Settings
Filters Tab

If the Perform by Server option is checked, any filter configured in this tab is put into the WHERE clause of the query sent to the database to retrieve data for the group. Otherwise, the configured filtering is performed by the reporting engine after the values are returned. It is recommended to leave this setting checked as the performance is much better.
Use the Event Type setting to retrieve events of a specific type. If all event types are required, select Any. For more information about specific Event Types, see the DeltaV documentation.
