Unexpected exit code 2 on Raspberry Pi

[chivakaa]

Hi,

I have not clear where is the mistake on script check_service, because some running service return exit 0 (OK) and others also running return exit 2

Evidence of exit 2 with running service on linux

root@emonpi(rw):nagios# ./libexec/check_service -o linux -t "service emonhub status"
