Is it possible to trigger alert if amount of traffic interface xmits/receives suddenly- (predefined time period,5,30,60 minutes) changes?
I am not talking about maximum or minimum tresholds.
f.e. its a 1 gb link, alerts are configured to fire if traffic reaches 900 mb or zero,
but i also want to fire alert if amount of traffic instantly drops lets say, from 800 mb to 300 mb, it means smth is not right in the network.
it will be possible if i can compare current poll results to previous ones, but i cant figure out how to do this in alert manager.
P.S. I am sorry if i posted in the wrong section of the forum
