Hi,
I've been using the "temp" check from xymon's plugins (on Debian) and wanted to ask if it was possible to excluce certain devices from the check. We have "problems" with an USB stick, which is permanently plugged into one of our machines and which does not have any temperature sensors or readings, but sometimes xymon decides it now has somewhere around 200 ?C, which is of course not possible.
It looks like the 'temp' script just parses the output of hddtemp to produce its report, so I think the approach is to make hddtemp ignore the drive. I think that, by default, hddtemp assumes that a drive temperature is reported by smart attribute 194. Running "hddtemp /dev/sda"? on a drive I know is supported, I'm told:
/dev/sda: ST500NM0011: 28?C
That drive model doesn't look to match any of the regexes defined in the first column of my /etc/hddtemp.db so if I add a line to that file:
"ST500NM0011" 0 C "ST500NM0011"
(where I think the first column is a regex matching the drive model, the fourth is any human-friendly description, and the 0 means "not supported") then when I run the 'temp' xymon script, the line for /dev/sda switches to clear rather than green and it's excluded from the rrd data.
Great approach, thank you. I entered my USB stick's data into the file and hope this changes things. By default, it shows up in xymon as
"drive supported, but it doesn't have a temperature sensor. (SanDisk)"
but every now and then it will trigger an error with temperatures above 150 ?C.
(Or: maybe the problem is just that your drive uses something other than smart attribute 194 to record the temperature? If so change the "0" to whichever attribute number is the right one)
Since it is a typical USB stick, it does not record temperature and all I get from hddtemp is
"SanDisk: drive supported, but it doesn't have a temperature sensor."
Thanks again, I hope this solves my problem!
Cheers Christoph
