I extend snmp and create scripts in each server.
If matrix is ok then i get no alarm, else alarm appears.

Now i have problem with blinking statistics.For example i get values from each minute, almost all of them are "0", but sometimes i see other values.
That other values generate me false alarm.

So question - how to setup threshold to avoid false alarms.
Maybe something with delta? 

EDIT:
Solved, simple change number of samples works.
