Alarm on Interface when goes to 0 traffic

[Martin Del Toro]

HI team
We have a couple of routers, that are interconnected.
Both use the te0/0/0 interface to make the interconnection.

Is there a way to make spectrum trigger an alarm, when there is not traffic traverssing through this circuit? If is not possible to alarm when there is not ttraffic trough the circuit, it can be  when there is no traffic through one of the "Te" interfaces of any of the 2 routers.

I was trying with the thresholds and watches option on each of the interfaces, I was thinking on use the % Total Utilization, but that does not allows to create thresholds for 0 % of usage.

Is there another option?

[Catalin Farcasanu]

Yeah, check for bits and not utilization. It should vary more, so you can set another value, greater than 0.

do you know by chance, how to create a watch to monitor this 0 traffic condition?

[Joseph Ackley]

Martin,

You can create a watch in the interface looking at the delta of ifInOctets or ifOutOctets and if the it drops below a certain value then alarm.

Be careful with creating watches on interface models. Watches are very expensive as far as CPU and memory. To many watches, especially on interface models, can cause serious performance issues.

Thanks, 
We will create a watch for this.
And thank for the warning on create a lot of watches and the performance issue, we will take it into account.

Greetings.

Glad to help
