Hi,
We use
check_cisco_envmon<https://www.monitoringexchange.org/inventory/Check-Plugins/Network/Cisco/check_cisco_envmon>
to monitor our Cisco equipment. It's using the ciscoEnvMonxxxxState 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.

Betreff: [Nagios-users] Monitoring temperatures on Cisco equipment
I'm looking to monitor temperature on some various Cisco equipment (2821, 3750,
4948, 6509, etc). I've looked at the
check_catalyst_temp.pl<http://check_catalyst_temp.pl> and check_env_stats.py
plugins, which both look in .1.3.6.1.4.1.9.9.13.1. I see and understand the
basic mechanisms of these checks.
What I don't understand is why both require warning and critical thresholds.
From what I can tell, both walk ciscoEnvMonTemperatureStatusDescr, check
ciscoEnvMonTemperatureState (and alert accordingly) AND also check
ciscoEnvMonTemperatureStatusValue to see if it's out of the warning and
critical thresholds specified on the command line. I understand why one would
want to be able to set custom thresholds (that would override "normal" and
"warning" states). What I don't understand is why are they required? Is there
a reason, or is it just an oversight? I don't have much experience monitoring
network equipment, so I'm wondering if there's a reason for it.
On that same note, does anyone know where those thresholds are stored? I see
in the same OID that there is ciscoEnvMonTemperatureThreshold, but that's an
absolute upper bound before a forced shutdown occurs. I'm assuming that the
thresholds for "warning" and "critical" ciscoEnvMonTemperatureState must be
stored somewhere else. Does anyone know where that is?
Unless there's a good reason for requiring -w and -c, I'll probably change one
of the plugins to not require them.
Thanks in advance,
Jeffrey.
