Trying to figure out the PCRE expression for Nagiosgraph Map

Well first of all you'd have to make sure that nagiosgraph also takes the
output in account.
It's always better to do that with perfdata...

You have the choice to also take the output as source to parse, although I
strongly recommend to use perfdata. That's what it is for.

The regex would look something like this:

/output:PROCS.*:(\d+) processes.*/

assuming that you don't care about the args and the status (OK, WARNING,
CRITICAL) part.
Only the digit (11) would be taken out of the output in this case.
