check-process.rb: Add verbose option to show what was actually matched

[axos88]

So basically I keep having false alerts when trying to match that only 1 process of a particular command is running.
I'm guessing the other processes are the checks themselves that seem to be running in parallel for some reason?

Can you please add a verbose flag that instead of saying that it found 2 or 3 processes matching the criteria, it would actually list them, similar to ps? process id, command, user, start, and whatever other info that seems informational?
