[hobbit] Hobbit compatible temperature monitor

We have a NetBotz appliance from APC which supports temperature probes.   I
use snmpwalk to query the MIB and produce a hobbit test which looks like:

            NetBotz Overall Status: normal(0)
          NetBotz Enclosure Status: normal(0)
                 Module Pod Status: normal(0)
                Location 1 Temp at: DC Temp. DCH2
            Location 1 Temp Status: normal(0)
           Location 1 Temperature : 76F
                Location 2 Temp at: Temp. East
            Location 2 Temp Status: normal(0)
           Location 2 Temperature : 70F
                Location 3 Temp at: Temp. West
            Location 3 Temp Status: normal(0)
           Location 3 Temperature : 77F
                   Humidity Status: normal(0)
                          Humidity: 34

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.

If your platform supports it you can use ipmitool for various internals.
Actual server room temp would need some external device such as the ones 
others have mentioned.

On a Sun X4150 box one of the sensors is Ambient Temp0. 
temp="`/usr/sfw/bin/ipmitool sensor reading 'Ambient Temp0' | awk 
'{print $NF}'`"

Other hardware has different sensor names, some just have (temp) sensors 
for CPU die temps.
