The Automated Maintenance Tasks page is a place where you can view and track recommended maintenance tasks scheduled for periodic execution. The tasks are integrated with the Health Check system and their execution has minimal impact on system performance. The tasks can also be manually executed from the interface.
In order to get to the Maintenance page in the Operations Dashboard, you need to go to Tools - Operations - Dashboard - Maintenance from the AEM Welcome screen, or directly follow this link:
