As logwatch/start is an argument, you should be able to use the -a 
option, which looks for arguments of a running process.  A helpful flag 
is -v which shows exactly what check_procs is doing, the more v the more 
details. -vv shows the ps command executed, -vvv shows the result set, 
so you get an idea of what's being parsed. An example, if I want to see 
if npcd is running on my machine, and is calling the cfg file, I'd use this:

./check_procs -w 2:2 -c 2:15 -a npcd.cfg -vv

Remove the -vv when you're happy with the results.
