Package: munin-node
Version: 1.2.6-10~lenny2
Severity: normal
File: /usr/share/munin/plugins/sensors_
sensors command returns a slightly different output than the
'sensors_' plugin expects:
$ sensors
f71858fg-isa-0a00
Adapter: ISA adapter
3.3V: +3.36 V
Vcore: +1.68 V
Vdimm: +3.31 V
CPU: 1364 RPM
Sys: 988 RPM
Sys: +43.5 C (high = +70.0 C, hyst = +60.0 C)
CPU: +21.0 C (high = +100.0 C, hyst = +85.0 C) sensor = Intel PECI

Core 0: +35.0 C (high = +84.0 C, crit = +100.0 C)
coretemp-isa-0001

Core 1: +33.0 C (high = +84.0 C, crit = +100.0 C)
coretemp-isa-0002

Core 2: +34.0 C (high = +84.0 C, crit = +100.0 C)
coretemp-isa-0003
Adapter: ISA adapter
Core 3: +34.0 C (high = +84.0 C, crit = +100.0 C)
And what the plugin detects:
$ cp /usr/share/munin/plugins/sensors_ sensors_fan
$ cp /usr/share/munin/plugins/sensors_ sensors_volt
$ ./sensors_fan config
graph_title Fans
graph_vtitle RPM
graph_args --base 1000 -l 0
graph_category sensors
$ ./sensors_volt config
graph_title Voltages
graph_vtitle Volt
graph_args --base 1000 --logarithmic
graph_category sensors
The problem is in the regex for both:
fan => {
regex => qr/^(\S[^:]*)\s*:\s+\+?(\d+) RPM.*?(\d+) RPM/m,
volt => {
regex => qr/^(\S[^:]*)\s*:\s+\+?(-?\d+(?:\.\d+)?)
V(?:\s+\(min\s*=\s*\+?(-?\d+(?:\.\d+)?)
V,\s*max\s*=\s*\+?(-?\d+(?:\.\d+)?) V\))/m
In both cases it's expecting there will always be more text following
the value and the "RPM/V" designation, but there is no text in my
case.
The fix is rather trivial, much like it's done for the "temp" regex,
where the part after the value is optional:
fan => {
regex => qr/^(\S[^:]*)\s*:\s+\+?(\d+) RPM.*?((\d+) RPM)?/m,
volt => {
regex => qr/^(\S[^:]*)\s*:\s+\+?(-?\d+(?:\.\d+)?)
V(?:\s+\(min\s*=\s*\+?(-?\d+(?:\.\d+)?)
V,\s*max\s*=\s*\+?(-?\d+(?:\.\d+)?) V\))?/m
I have also checked the file in latest munin-node package (1.4.4-1 at
this time) and it's the same there too, as well as in the
munin-monitoring.org trunk source (except that the regex there is
commented).
