Can anyone offer advice, please, with regard to monitoring the system
resource consumption of a zcx Container task?
I've got a zcx Container task running on a 'sandbox' system where - as yet
- I'm not collecting any RMF/SMF data. Because of that, my only source of
system usage is the SDSF DA panel

Is there a way to capture a MODIFY command ?

Your question is unclear. By capture, do you mean log to a dataset or suppress?
In neither case would IEFBR14 have any relevance. Exactly what are you trying
to do and exactly what did you attempt?

Hi Peter,
If you have SDSF, you can write a Rexx program to scan the SYSLOG
(either active or offloaded) for messages output by your modify command.

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.

II can't speak too much to the excp counts, but re: CPU usage.
Unix systems "count the beans" very differently than z/OS.
The "system overhead" (uncaptured CPU time) for z/OS averages about 10%.
The Unix systems I have encountered routinely exceed 40%.

I can’t check my zCX out right now since my internet is down.
You are running these on zIIP engines correct? Must be nice to have 5
zIIPs! And have the WLM parts in place? Although it probably wouldn’t
make much difference during startup/shutdown.

Allan - "...count the beans differently...' Yes, I'm beginning to get used

You could use a System REXX to issue the command and process the output,
example:
/* REXX */
CmdResult=AXRCMD('F STARTEDTASK,STATUS','OUTPUTVAR.',40);
Do I = 1 to OUTPUTVAR.0
Parse var OUTPUTVAR.I p1 p2 .
/* do someting here */
End

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 t

You know, I would think it would be possible -- nearly trivial -- to write a
generic Rexx script that would issue any arbitrary console command, collect the
results, and do "something" with those results -- where "something" was any of
the things Rexx can do, such as writing it to a file. Would
Why would you expect REXX to be started with SDSF in the table? SDSF is a TSO
command and establishes an ISF environment; if it can run under IRXJCL and
System REXX then it can run REXX scripts there..

IMHO the key to running system efficiently is to assure enough physical
memory.
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

The OP does not need the response to the modify, but rather the output from the
task when it processes the text in the CIB. That might be difficult if the task

No, this FC is kind of license. There is no hardware behind and
