Hi,
I currently use APA for monitoring heavy application outside from DB2 or

I'm really far from a heavy use but I can say it works properly cause it
helps me in optimizing applications.
It's my opinion it's a good tool for cpu bound application, a bit less for
discovering elapsed time

I do not remember that IBM has ever characterized its defaults as

to do---with, I think, reasonable success---is to provide defaults

Your case if you could read the VPS control file with the printer names/IP
