Question : Cisco - Graphing Temp?

I have a Cisco 3845 router, and am using MRTG to graph CPU and Interfaces.

Is there a way to graph temperature?  I'd like to actually graph the real temp.  But I think within IOS there's also a way to set thresholds and do an SNMP get to query the status of those?

But if possible I would prefer a way to do an SNMPGET and have it return the current ambient temp in degrees.  

Thanks,
Shane

Answer : Cisco - Graphing Temp?

It's supported on the big Catalyst chassis, but I can't find anything near this for the router chassis

There are some very specific router images that support this OID, but nothing for the 3800 series..
