Re: [Nagios-users] Monitoring temperatures on Cisco equipment
Hi, We use check_cisco_envmonhttps://www.monitoringexchange.org/inventory/Check-Plugins/Network/Cisco/check_cisco_envmon to monitor our Cisco equipment. It's using the ciscoEnvMonState value only. I don't know if the thresholds are available through snmp, but you can view them by entering show environment alarm thresholds on the device. gerald Von: Jeffrey Watts [mailto:jeffrey.w.wa...@gmail.com] Gesendet: Mittwoch, 26.

Re: [Nagios-users] Monitoring temperatures on Cisco equipment
I think you misunderstand. Those two plugins return WARNING or CRITICAL if one of the two things occur: 1) If the ciscoEnvMonTemperatureState is not normal. 2) If the passed -w and -c values are less than ciscoEnvMonTemperatureStatusValue. What I'm asking is why #2 is _required_. I can understand it as an optional check if you want to override the device's defaults, but not as mandatory behavior. Cisco devices are smart and know when they're warm or hot. That's the purpose of the ciscoEnvMonTemperatureState. I'm just trying to find out why folks feel that overriding Cisco's defaults is necessary behavior. Thanks, Jeffrey.

Thanks Gerald, that's exactly what I was looking for! Jeffrey.

While I don't have any insider knowledge into *why* it is the way it is, I'll take a guess - most third-party plugins come into existence because they satisfied someone's specific needs. Perhaps the original author needed to further narrow the range of good-vs-bad, who knows? I'd say modify it to your needs. :) Benny (yes, *that* Benny, hi Jeffrey) -- Hairy ape nads.-- Colleen, playing Neverwinter Nights -- Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!
