[linux] munin cpu plugin

[Marek Podmaka]

Cau,

Hmm teraz ma napadlo... je to jeden fyzicky CPU a hyperthreadingom. Ze
by zrovna tento kernel hadzal nespravne data do /proc/stat kvoli HT?
Teraz som si skusil zratat ci hodnoty pre cpu0+cpu1 = cpu a sedi to
+/- 1.

Munin plugin aj tak cita len celkove cpu, nie jednotlive:
awk '/^cpu / { print "user.value " $2 "\nnice.value " $3 "\nsystem.value " $4 "\nidle.value " $5 "\niowait.value " $6 "\nirq.value " $7 "\nsoftirq.value " $8 }' < /proc/stat
