I am trying to simplify my power alerting and was hoping to use traps to acheive a streamlined power alerting system.
Presently all of my APC UPS' are very precariously configured using email alerts to notify us of problems like power loss, bad batteries, iminent low battery shutdowns, etc. its a pain to make sure all the configs are correctly copied to each and every unit.
I am working towards using traps and the trap alerts to notify me of these changes, so that instead of sweating the config of each new UPS, I can just plug in the trap server and I am done. I can manage the necessary alerts on one box (orion) instead.
The problem is I dont need to know every power hiccup that my UPS sees. I only care if its been on battery >30 sec. The UPS only sends traps for a change in status, and not repeating at an interval as far as I can tell. I unplugged one of my UPS' and waited 2 mins, and I only received one each on battery/off battery trap.
Is there a way to setup a trap that if one condition is met, and another is NOT within a span of time it will alert?
For instance, if it gets a PowerNet-MIB:apc.0.5 trap (on battery) and does NOT receive a PowerNet-MIB:apc.0.9 (off battery) trap within 30 seconds it should fire an alert that its on battery. if it DOES receive the 09 trap within the 30 second window, it should not fire the alert.
My goal is to only alert a major power hit, and avoid the alerts due to dirty power that will cause a UPS to switch to battery for a second or two, often several times a day at some sites.
Ideas?
