What an I doing wrong?

viewtopic.php?t=56124 was some help, but still no joy

I just need the temp from each physical CPU - from these lines
Physical id 0: +52.0°C (high = +79.0°C, crit = +89.0°C)
Physical id 1: +49.0°C (high = +79.0°C, crit = +89.0°C)

Running check_temp.pl from the SLES 11 box locally

later to get the temp in nagios via nrpe
- already using nrpe to get disk space & remote load status of this server

Thanks for reaching out @Kyetech IT manager,

Don't worry, I don't think you're doing anything wrong. I tried out the plugin myself and I noticed a possible bug.

If you look around line 115 in the plugin, you'll see the regex that the plugin is matching against The issue is that the degree symbol "°" seems to take up two characters. I was able to fix the bug by adding the pattern match at the end to include to characters before [CF] Let me know if this fix works for you

Hello danderson;

Add in the extra dot in the filter line helped and is working now both locally & with nrpe
- now to mention to the creator of this lovely script

Thanks a lot. You get 1000 points.

Glad to know you got that issue fixed!
