Microsoft published yesterday the Technical Preview 2 bits for System Center 2016
What’s New in OM in Technical Preview: Maintenance Schedules
Maintenance mode is a feature in Operations Manager to suspend monitoring of an object during regular software or hardware maintenance activities such as software updates or hardware replacements. When an object is placed into Maintenance Mode, all work-flows targeted against that object are suspended during that specific interval. This prevents Alerts and Notifications from being generated by the work-flows targeted against the object in Maintenance Mode and helps reduce alerting noise during a planned maintenance activity on the server. In Maintenance Mode, alerts, notifications, rules, monitors, automatic responses, state changes and new alerts are suppressed at the agent.
Entities can be put to Maintenance in older versions of Operations manager but they cannot be put into maintenance mode at a future time. The newly created Maintenance Mode scheduling wizard gives the ability to choose different types of entities to put to maintenance mode and to schedule Maintenance at a future time through many different scheduling frequencies such as one-off/daily/weekly/monthly. It also gives the ability to view all the maintenance mode schedules that have been created in a single screen and also gives the ability to schedule multiple jobs for the same monitored entity
