Hi Peter,
If you have SDSF, you can write a Rexx program to scan the SYSLOG

If you have a normal privilege level then you'll need to read the messages from
the log or from the started task. Under SDSF you can display the started task,
capture the messages with XDC and edit the output to remove extraneous messages.

You know, I would think it would be possible -- nearly trivial -- to write a

Enough mean paging rate close to zero during normal operation.
Paging is still good, but only clean out inactive pages (looong time).
However DAT is in use even with no paging - just to translate virtual
storage

SDSF has distinct environments that it natively supports on z/OS :
1. ISPF
2. TSO CPPL
3. Batch (and AFD)
4. REXX
The SDSF REXX interface will run where there is a valid REXX environment.
Note that the batch SDSF interface has been stabilised and we now encourage
users to convert
You could use a System REXX to issue the command and process the output,
