HPUX server monitoring (Quick 10 pointer!)

[Charles Harris]

Dear all,

Just a quck question, is there a way of telling a servers current temp? - without going to have a look ;-) / any idea what warning, if any, are sent to the syslog before a thermal shutdown occurs ?

Any tips, pointers, RTFF's warmly welcomed as usual!!

Cheers,

I don't know if we can get the temperature but you can certainly configure "envd" daemon to report errors to syslog or run commands by using /etc/envd.conf.

Look at the example file in /usr/newconfig/etc/envd.conf.

Make modifications and move it to /etc and restart envd by sending it a SIGHUP signal (kill -1)

Hi,

The quick answer is no. Here are a couple of threads along the same lines as this one:

I think EMS will monitor the temperature on the newer systems. It comes up in one of the threads above.

I have heard of temp monitors that communicate with ITO via SNMP traps, but I don't have any details.

I dont think there is a way to tell the curretn temp , but you can attach may be a digital thermoter and make the seriakl port read the temp uisng a simple C program.

Hi Chaz,

You need to check the syslog.log for OVERTEMP
grep -i overtemp /var/adm/syslog/syslog.log

When it first goes out of bounds you'll get WARNING msgs - when it approaches shutdown temp you'll get CRITICAL msgs. If not abated it will eventually force a shutdown.

Rgds,

You may want to look at the EMS Hardware Monitor application that will alert you on certain hardware conditions (i.e. temp) and give you the ability to possibly respond before a critical failure.

Charles, I should have added (since I neglected to ask), that mainly the N, L and A servers are intelligent enough to shutdown when the temperature is way too high.. And although it does not work with all of your devices in your system, this might be a good place to start...

I remember a post by Bill Hassell from HP speaking of purchasing a type of thermometer to monitor temp conditions..

Hope this helps.

Thanks for all the advice, as it turns out, the air-con in our server room has restarted - so panic over!

Thanks again for all the useful info!

Ps. The points thing doesn't seem to be work, I'll slap them on as soon as I can!!

Michael,
"that mainly the N, L and A servers are intelligent enough to shutdown when the temperature is way too high"-
as far as I recall _every_ S800 HP server I know (from 825 up to Superdome) came with a temp sensor. I guess that's why HP can provide envd as part of the os;-)

Hi,
Normally EMS is configured for such things. When a cabinet fails, it sends a message about this. So you will be informed just in time !!!
