Queue Management provides visibility into data sources that are currently queued or in progress for discovery. Organized by collector groups, entries in the queue are listed in their scheduled order of execution.
Queue Management can be accessed by clicking the Manage Queues button on the main Discovery Management page. 
Prioritizing data sources
The discovery execution order can be adjusted to prioritize specific data sources. To do this, select the checkbox for the desired data source, then click Move to Top or Move to Bottom to update its position in the queue.
Note - Reordering discoveries can be performed for single or multiple discoveries.
