[Nagiosplug-help] checking if a process is running on Linux

[Bob Ingraham]

The check_procs command takes a "range" for the -w and -c options that
allows you to specify either a minimum, a maximum or both for the number
of processes that you are monitoring.

So, for example to specify a minimum of 10 "ping" processes for warning
level notification and a minimum of 5 for critical notification, you'd
specify:

./check_procs -w 10: -c 5: -C ping

>From the "check_procs --help" output:

RANGEs are specified 'min:max' or 'min:' or ':max' (or 'max'). If
specified 'max:min', a warning status will be generated if the
count is inside the specified range.

I believe this is the behavior that you are looking for.
