'''!NADA - !Not Adaptive Thresholds'''
All graphs were generated with OpMon by OpServices
The server load example:
As you can see, my routine backup, running from 00:00h to 00:30h increases server load up to 5. With my fixed thresholds, i would probably receive an alert regarding CPU Utilization because server load has exceeded the defined fixed boundaries( 1 for Warning and 2 for Critical ).
What you can see in the graph are actually my baseline, in other words, if server load remains in between those two lines, no alert will be generated, because this is the default server behavior. Baseline tends to be more accurate through time, the more data to be analysed the more accurate baseline.
Think about it, if backup is supposed to happen and by some reason it does not? In this case, load will remain low during backup time, generating an alert, probably taking me out of my chair to verify what happened last night.
