[Freeipmi-users] Temperature sensors disabled or abnormally cold: Can alerts be sent?

[Ryan Cox]

I'm trying to use pef-config (or any tool that will work) to have a Dell 
PowerEdge M610 send alerts when a temperature sensor is disabled or has 
seriously erroneous data, like reporting a processor to be at 5 degrees 
C.  Here is an example:

# ipmitool sdr type Temperature
Temp             | 01h | ns  |  3.1 | Disabled
Temp             | 02h | ok  |  3.2 | 5 degrees C
Ambient Temp     | 08h | ok  |  7.1 | 26 degrees C
IOH ThermTrip    | 35h | ns  |  7.1 | Disabled

From a good server:
# ipmitool sdr type Temperature
Temp             | 01h | ok  |  3.1 | 26 degrees C
Temp             | 02h | ok  |  3.2 | 34 degrees C
Ambient Temp     | 08h | ok  |  7.1 | 24 degrees C
IOH ThermTrip    | 35h | ns  |  7.1 | Disabled



The processor sensors are the ones I care about (3.1 and 3.2).  A server 
was affected by a power event (surge or sag... not sure) and the 
processor temperature sensors are having issues for some reason.  The 
CPUs are throttled as a result and that is logged via syslog.  We can 
take care of the hardware issues just fine, but I am hoping to have our 
servers notify us of problems in a way like alerts for an ECC threshold 
error (entry in event log, snmp trap sent, amber light).  I played 
around with pef-config for a while and can't figure out how to make it 
alert when a sensor is disabled.  I'm also not sure if the alert would 
only happen on a cold boot, etc, so I'm not sure if maybe I do have it 
configured correctly but just can't test it.  The affected servers are 
still in use until user jobs on them are finished, so I can't reboot 
them until that time.

Here's an example of a config I was working with:

In this attempt, I was trying to have it essentially alert for 
everything and then narrow it down from there.

A few things I'm unsure about: What is Event_Data1_Offset_Mask and is it 
set appropriately for what I want to do (I used an existing temperature 
policy from the blade as a template)?  This is my first time messing 
with pef-config, so I'm a little confused by it to be honest.  I know 
how to checkout, diff, commit, etc, but am having trouble figuring out 
what to put for some of the values.

Any thoughts?  Am I going about this the wrong way?

Thanks
