Use this activity to check the synchronization service queue. You can perform this on the Synchronization Service Queue page.
The Synchronization Service Queue displays the current state of tasks that the synchronization service nodes are processing. As each task is completed, it is removed from the queue. If there is a high load on the synchronization service, you will see records on this screen. Otherwise, the queue will be empty.
