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

in T332764 we are looking at migrating checks from nagios to icinga and at the same time trying to understand if they are still valid or if they could be improved. When considering this check i wonder if its still of value. i looked at logstash and alerts for as long as logstash has logs. If this is still valid then:
So, a few notes:
Given all this I think we should just consider this task obsolete and remove any existing alerting we have.
