As a part of routine IT maintenance, it is common to bring the device down or restart it. This even applies to your critical IT devices such as a router, switch, or a server. Though you are aware of such maintenance activities, what if your network monitoring software pushes onto you too many associated alerts?
Most applications have options to inherit your on-field intelligence by scheduling a downtime. It enables the network monitoring software to pause the routine monitoring presets for those selected devices during the maintenance time slot.  
Are there any fixed patterns to schedule such IT maintenance activities? 
Absolutely no! At times, they are specific to industry, organization, IT infrastructure or even an adhoc maintenance plan that has to be scheduled instantly. 
As you all know, OpManager has the Downtime Scheduler (“Advanced fault management) functionality with options to schedule maintenance period Once, Everyday or Every week. With the latest hot-fix, we’ve also included an option to schedule downtime Every month, for instance… 1st of every month or last day of every month or even third Sunday of every month and more…
Here is the snapshot of the new downtime scheduler screen, Hope you find it useful.
So, for those who are using downtime scheduler, feel free to try the new inclusion and share your feedback with us at “opmanager-support@manageengine.com”. If you’ve not tried it before, give it a try and let us know how it worked for you.
