I use some APC environmental monitors (model AP9319) and I have an external script I'd be happy to provide to the community.

they seem to retail for about $200 now.

I have never been able to get custom graphs working, so I am not graphing the output. But getting custom graphs is not high on my priority list.

Well, devmon could be a convenient method to poll the device, and would make getting graphs and alerts quite easy.

It might be, but since it doesn't support snmp v3 I have not been able to use it. mrtg does support snmp v3, has templates, and bbmrtg.pl is pretty stable for importing the states into hobbit.

Yep. We graph temperature and humidity (as that is the base sensor included in the package). just queried via SNMP.

Here you go! all of our sensors are in climate controlled rooms, so humidity is not a concern. This reports them both on one page, but only alerts if temp is out of range. would be a trivial update if someone wanted to alarm on humidity thresholds...

I have written many externals using this template. I use the same model to pull over 500 firewalls for 10 data points each in less than 30 seconds.

I'll leave the NCV stuff up to you. add an 'apctemp' test to your hosts and off it goes! Have fun!

Hobbit script to monitor APC Environmental monitors

Written by Stewart Larsen

Released to the public domain

This uses bbhostgrep to figure out which hosts to

poll and then Net::SNMP to poll them Asynchronously.

This incorporates nicely into the NCV graphs As well.
