Add Icinga check for CPU frequency on Dell R320
Closed, ResolvedPublic

Description

Our Dell R320 servers have a hardware bug which makes them sometimes drop to less than 200 MHz CPU frequency. This is hard to notice except when observing indirect effects of the system being slow, so we should have a separate Icinga check as long as we're using those server type:

[18:33] <bblack> simple shell command to check for cpu0 speed < 800Mhz: test $(grep MHz /proc/cpuinfo |head -1|cut -d: -f2|cut -d\. -f1) -gt 800 || echo fail
