Subject: [mrtg] APC Environmental Monitor
Has anyone had any success with graphing the Temp/RH on the APC Environmental
Monitoring Unit (AP9319)?
Here's a better description of the model:
http://www.apc.com/products/family/index.cfm?id=47
I've done an snmpwalk on the thing and can't find anything providing the temp
or RH.
If anyone has accomplished this on this unit can you post (or send me) a sample
configuration file? I've seen a lot of posts on getting this information from
APC UPS's but not specifically this Environmental Monitoring Unit.
If you need any more details I can provide them.
Thanks.
-Josh
