Thank you for this! You saved me so much digging. I got the same bullshit error that you did, and google led me here. I was also trying to compile libtorrent-rasterbar.

Ciao BenV,
Sorry for the delay of my answer, but since the command “sensor” did not include any output on my machine, I tried to install the drivers of the manufacturer. Unfortunately, the “sensor” command still does not give any result. We are investigating.
Ciao
Loreto

Note that I just updated the package, this version also includes a PNP4Nagios template and a little man page for the check.

And you’re right: lmsensors doesn’t work on virtual machines, or at least, that’s my experience so far.
On the physical machine it should work however, depending on the sensors in your machine and whether or not they are supported by lmsensors (and in your kernel).

The check_mk lmsensors plugin expects ‘/usr/bin/sensors’ to exist and to provide output. For example, my server here at home outputs this:
benv@server:~$ sensors
lm85-i2c-0-2e
Adapter: SMBus I801 adapter at 2000
in0: +1.56 V (min = +0.00 V, max = +3.32 V)
Vcore: +1.34 V (min = +0.00 V, max = +2.99 V)
+3.3V: +3.33 V (min = +2.97 V, max = +3.63 V)
+5V: +5.10 V (min = +4.50 V, max = +5.50 V)
+12V: +12.00 V (min = +0.00 V, max = +15.94 V)
fan1: 1361 RPM (min = 0 RPM)
fan3: 952 RPM (min = 0 RPM)
fan4: 1251 RPM (min = 0 RPM)
temp1: +63.0 C (low = +0.0 C, high = +75.0 C)
M/B Temp: +49.0 C (low = +0.0 C, high = +65.0 C)
temp3: +39.0 C (low = +0.0 C, high = +55.0 C)
cpu0_vid: +1.088 V

Can you check if you have the tool and post the output here, and/or email it to me?

loreto: can you post/mail me the output of ‘sensors’ and ‘check_mk –debug –checks=lmsensors.temp -II localhost’ (if you think the temperature sensors should report something, otherwise ‘lmsensors.fan’ or ‘lmsensors.volt’)?

Installation on check_mk Linux server has been successful (following your instructions)
“check_mk -II localhost” doesn’t reports any lmsensors data.

danielbair: I guess your version of check_mk doesn’t include the definition of saveint/savefloat yet. If upgrading to a newer version isn’t an option you could try to remove the savefloat function in perfometer/lmsensors.py (lines 9 and 10), it should still work if the check reports good values.

The bar graphs on the right side are not working for me. I just get “invalid data: global name ‘savefloat’ is not defined”

I am running OMD on Ubuntu 10.04 LTS with check_mk version 1.1.9i8

kadu: did you read my post? Your problem is literally in there, with the only difference that you have it in lib64 and I had it in lib. Just run the sed line as I did and it should work.
