If you also have network monitoring requirements, the client code that I
wrote for the Hobbit network monitor can do some of this. It can be
configured to watch the paging space and optionally send alerts at a
certain threshhold.
If you already have a network monitor, perhaps the program can be
modified to work with it. Or it could be just used stand-alone.
You can find Hobbit here:

If Endicott spends any time on this "opportunity", related to what you
said about the situation of going from 90% page full to an abend is the
spool going from 90% and putting out an HCPPGT401I message to 100% and
putting out an HCPPGT400I message. On any system I have ever supported,
I want to be notified way before the 90% mark. A looping user can take
the spool from 90% to 100% very quickly.
I would prefer to be able to set the message threshold(s) in SYSTEM
CONFIG. Ideally, I would like to see a message put out if there is a
sudden, big change.

Any work we do in this area, to force users instead of abending, will

paging. Airbags were not invented so one could drive like an idiot.
And Rob has a good point about what people would notice and
that will be part of the challenge, getting their attention.
However, part of it is buying a little more time to react. Often the
odd scenario that creates this takes you from 90% full to abend in
the time it takes to figure out who to call. Also, I'll be looking
into how z/OS handles the scenario as some customers feel z/OS
handles it with more grace (or is it mercy).
