[mrtg] Math for temperature monitoring

[Isaac Grover]

Hello everyone,

I would like to monitor our Xylan equipment's temperature via mrtg
and have found the following four OIDs that may be of some use to
me:

1.3.6.1.4.1.800.2.1.5.1.0 (chasEnvrmnt1TempRange1.0)
1.3.6.1.4.1.800.2.1.5.2.0 (chasEnvrmnt1TempRange2.0)
1.3.6.1.4.1.800.2.1.5.3.0 (chasEnvrmnt2TempRange1.0)
1.3.6.1.4.1.800.2.1.5.4.0 (chasEnvrmnt2TempRange2.0)

The first two OIDs consistently report an integer value of 4, and
the last two report an integer value of 2.  Xylan's tech guys don't
know much about SNMP, just how to fix broken topologies.

Could anyone help me out with the math to make sense of these
numbers for an actual human?
