Softwareanforderungen

  • sensors (optional)

Installation

Source

Arch-Linux

pacman -S lm_sensors

Crux

prt-get depinst lm_sensors

Debian

apt-get install lm-sensors

Gentoo

emerge lm_sensors

SuSE

yast -i sensors

Konfiguration

Link setzen.

ln -s $SOURCEDIR/VDR/PLUGINS/src/sysinfo/script/sysinfo.sh /usr/local/bin

Laut README muß die sysinfo.sh nur dann angepasst werden, wenn keine Daten im zweiten Block der OSD Ausgabe zu sehen sein sollten.

Cpu Temp:  xxxxxx       Fan1:  xxxxxx
M/B Temp:  xxxxxx       Fan2:  xxxxxx
bash> sysinfo.sh

Usage: sysinfo.sh {cputemp|cpufan|mbtemp|mbfan}

Bsp:

bash> sysinfo.sh cputemp

Bekommt man hier keine Ausgabe, ist sensors aufzurufen.

bash> sensors

Wir nehmen das mal auseinander.

sensors | grep -i 'CPU TEMP' | cut -c 10-18 | tr -d ' '
          ^                    ^              ^
          ^                    ^              Löschen der Leerzeichen
          ^                    ^
          ^                    Gibt 'characters' aus, zeichen 10 bis 18
          ^
          Suchphrase lautet 'CPU TEMP', '-i' steht für 'ignore case distinctions' GROß/klein Schreibung

Folgende Änderung:

- sensors | grep -i 'CPU TEMP' | cut -c 10-18 | tr -d ' '
  sensors | grep -i '^temp1:' | cut -c 10-18 | tr -d ' '

Nun sollte sensors den gewünschten Wert ausgeben:

bash> sysinfo.sh cputemp
 33°C

Bei den anderen Daten ist ähnlich zu verfahren.

Probleme

  • Bei älteren Versionen von "ps" (welches genutzt wird um "cpu free" anzuzeigen), kann es Probleme mit der Syntax geben sysinfoosd.c:
// Calculate cpu free
ExecShellCmd("CPU=0; for I in `ps -eo ""%C"" | grep ""\\.""`; do CPU=`echo $CPU $I | awk '{ print $1   $2 }'`; done; echo $CPU", cTemp);
                               ^^^^^^^^^^^^^
  • Sieht man am besten auf der Konsole, anstatt einzelne WERTE... wird (not found) ausgegeben:
~# ps e%C
spec value %C not found
  • Änderung:
// Calculate cpu free
- ExecShellCmd("CPU=0; for I in `ps -eo ""%C"" | grep ""\\.""`; do CPU=`echo $CPU $I | awk '{ print $1   $2 }'`; done; echo $CPU", cTemp);
  ExecShellCmd("CPU=0; for I in `ps xu | awk '{ print $3 }' | grep ""\\.""`; do CPU=`echo $CPU $I | awk '{ print $1   $2 }'`; done; echo $CPU", cTemp);
