I have more than 400 monitors setted up and I have them grouped in several groups, according to their type (ie. servers, access points, ups´s etc.) an location (ie. branch).
In every group there are critical monitors and not so critical monitors.
I need a report for the previous month, showing all the downtimes that exceeded certain amount of time for my critical services.
ie. all the downtimes that lasted more than 5 minutes of certain specified monitors.
How may I do that? I just cant find the way!
