Trafic utilization alerting

Help
1

Hi everyone,

I’m looking for some “specific” port utilization alerting.
I’m looking for a dynamic threshold monitoring.

Instead of checking the ifInOctets_rate / ifOutOctets_rate (ports.ifInOctets_rate >= xxxxx) and compare it to a a static value, I would like to compare value from previous polling to the actual one, in order to check if we observe a decrease (or increase) of X % (not looking for the macros that check the percentage of the if speed either)

Is LibreNMS natively capable of this?
I’ve heard about Macros, but not 100% sure if it’s possible and how to do it.

I looked at just this yesterday, I don’t believe it’s possible as we only ever have the rate of the current poll, not the previous rate which is needed to calculate the drop.

Hi, laf.

Thanks for your feedback.
That’s what I’ve unfortunatly found, but wanted to double check if someone here already found a way to do it.

Thanks for our help.

Is it possible to run alerts off bills?

Hi,
I’ve eared that alerting on bills is not 100% reliable, but can’t remember why :thinking:
From my side, I’m using Bills also, to do some aggregate graphs, but alerting on this seems not reliable from what I’ve eared.
