The event filter allows you to search the audit records for certain events.
To add the filter, click on Manage Filters, then click on the Event tab.
To activate the filter, simply click on the checkbox to the right of the filter.
The list will be populated according to the events available. The system has many types of events, so you should select the events according to your needs. For example, if you want to search for changes to objects (when a user changes an object), select the Changed event. If you want to search for added objects (when a user creates a new object in the system), select the Added event.
Select the items you want by dragging from the left list to the right list.
