Check Temperature

QUIRICONI — Wed, 08 Oct 2003 07:54:48 GMT

Hi all,

I would like to know is there is a command or
a log file to check the temperature of my system...
I had under one of my servers :
Temperature exceeded the OVERTEMP_CRIT...

Thanks.
Jean-Remi.

Hi Jean-Remi,

Nope, sorry there's no command or call that will return the actual temp. Best you can do is see the different alert values. And as you've seen that's the next to highest & cause needs to be determined & corrected.

Rgds,
Jeff

In general, the answer is no. There are interrupt routines that are invoked when set points are exceeded. A far better approach is to purchase a digital thermometer with a serial interface and use that instead.

Jean,

You've probably figured-out the envd daemon and its config file /etc/envd.conf

However, although I've added a bit to the configuration (it announces to the systems management environment that the server is about to shutdown immediately, before it does so). I too have never figured-out how to get the current temperature.

I know its a bit cheeky, but if your environment includes an IBM P-Series, you'll find the /usr/lpp/diagnostics/bin/uesensor -l
command is probably sufficient for this requirement.

(Is that a big enough hint of what I'd like to see in a new release of HP-UX?)

I dont know the answer but I collect the temperature of our switch by polling it using SNMP.The MIB given by the vendors helps find us what to poll(OID).
Fairly straight forward but the vendor has to put the capability in a device to do so.
