Not simply. Note that the output to stdout/stderr from your perl script
is written to a file on your test machine. When the Perl script that you
are running via a <process> element in a STAX job completes then STAF
reads the contents of the Perl script's stdout/stderr file and returns
this data in the STAF/Process/End message that is sent to the STAX service
to let it know the Perl script completed. So, while the Perl script is
running, the contents of the Perl script's stdout/stderr file are not
available. You could run another task in parallel with your Perl script
(e.g. using the process-action element) that continuously loops and runs a
<process> that runs the "tail" Unix command (or another command) to get
the last contents of the stdout/stderr file that your Perl script is
writing too and log it.
Or, if your Perl script is STAF enabled (e.g. if you submit STAF service
requests within it) then you could submit LOG request to the STAF Monitor
service to log messages about the status of the Perl script which will be
displayed in the STAX Monitor. This is described in the "Monitoring a
Job" section in the STAX User's Guide at
http://staf.sourceforge.net/current/STAX/staxug.html#Header_MonitorJob
which says:
For each <process> element represented in the "Active Job Elements" view
in the STAX Monitor, if the process generates STAF Monitor Service
messages (see section 8.9 of the STAF User's Guide), the current monitor
message is displayed to the right of the process name and elapsed time.
The monitor information is periodically refreshed while the process is
running. If the process has not written any STAF Monitor information, the
text "No STAF Monitor information available" is displayed.
You said that when you log the stdout/stderr data from the Perl process in
the STAX Monitor that it shows up as one line. This is probably because
of it using different line ending characters. Instead of logging the
entire STAXResult output, you could read the data in STAXResult's
stdout/stderr data line by line and log each line separately if desired,
etc.

Subject: [staf-users] How to print return message in parallel on
STAX UI monitor during script execution
Hello Staf users,
Is there any possible way to display all the return messages from my test
(perl) script on execute in parallel on STAX UI Monitor?
I'm using both <stafcmd> and <process> method to run the test (perl)
script.
If I use STAFResult to display all the result in STAX UI Monitor. It
displays all return message in a single line which is also not in proper
format to view.
Please help..
Thanks,
V Raja
