Re: Server Temperatures

FYI, I updated this script today to be more robust. Linked here (instructions are here too for the Python novice):
http://todd.dailey.info/archives/2005/02/22/xserve-temperature-logging/

Or just get the script here.
http://todd.dailey.info/files/xserveg5logger

Also, if you want to see what serveradmin is capable of monitoring, this command:
sudo serveradmin command xserve:command = status | egrep "(location|current-value|type)"
is a little easier to read than slogging through all the other text.

Please let me know if you have errors running the script on an Xserve G5. Note that the script currently won't run on an single cpu Xserve G5, but you could make it work just by commenting out the CPU 2 sections.

Is there any information about the normal operating range temperatures

enough, but can't seem to find anything. Currently, our XServe is
running at the following:


 Between the Processors        : 32.00 C
 CPU 2 Ambient                 : 30.00 C
 CPU 2 Internal                : 40.36 C
 Behind the DIMMs              : 53.00 C
 PCI Slots                     : 48.00 C
 CPU 1 Internal                : 47.93 C
 System Controller Ambient     : 40.00 C
 System Controller Internal    : 51.38 C
 CPU 1 Inlet                   : 24.00 C
 CPU 1 Ambient                 : 35.75 C
 CPU 2 Inlet                   : 22.50 C

If you run:
sudo serveradmin command xserve:command = status | less

You can find the thresholds for each parameter, the units are 1/65536 of a C degree.

So, for example, for CPU 1 it shows maxWarningThreshold as 5636096, which is 86C, and maxFailureThreshold as 5898240, which is 90C.

I wrote a python script to log these temps here:

Unfortunately, the sensor numbers appear to change from server to server, so I need to update it to work off the sensor name, not the sensor number. The current script doesn't work quite right on all systems, but you can look at it and get an idea of what I'm doing.
