Monitoring Dell PowerEdge
Servers with MRTG
4/1/2003 (updated 4/22/2003)
This document describes
monitoring Dell PowerEdge specific hardware in both the Windows
and Linux environments. Items that can be monitored appear in the
Dell OpenManage application, these include various temperatures,
fan RPMs, and power supply voltages.

Dell SNMP OID Definitions
These will vary
depending on the hardware configuration of your Dell server. These
examples are from a fairly robust PowerEdge 1600SC. (Dual processor,
hot-swap bays, etc.) A lesser 600SC produces near-identical results
however.

If you look
closely at the OID results of an SNMP dump of a Dell server (or
the table above) you'll notice the categorical groupings of the
various fields (700 for the temperatures, 600 for the power levels,
etc.). Here is a comprehensive explanation of those groupings:

10892 MIB definition: |

Examples
As you know,
when you're pulling straight SNMP values, it doesn't really matter
whether you're running MRTG from Windows NT or from Unix. We run
it successfully on both platforms on PowerEdge hardware with no
problems. Here are a few sample MRTG configurations based on the
above values.
Example #1 - CPU Temperature

| Max Out: |

`Monthly' Graph (2 Hour Average)

In this example,
we're converting the SNMP result from Celsius * 10 to Farenheight.

Now, this example
is much more straightforward, as we don't have to do any math on
the SNMP result. It is the actual RPM number....
