In my new server, a sensor for the ACPI plugin reports 0 K (-273.15 C) as temperature. So, the graph is absolutely useless as this temperature (absolute zero, obviously wrong) makes all the other temps to look flat.
According the documentation it's possible to disable a field, by writing
thermal_zone2.graph no
in munin.conf
, but it isn't working. How can i disable that graph? Or otherwise force the y axis minimum to 0° C
