You can run top (or probably seagull) as follows using xterm for the shell and
exporting the display. In this example I'm starting "top" on a Linux machine
(staf1e) from a Winodws machine. This example also stops the process using its
STAF handle. You can do the same thing via a STAX job.:
C:\>STAF staf1e PROCESS START SHELL "xterm -title %T -e /bin/sh -c %X" COMMAND
"top" TITLE "top" ENV "DISPLAY=:0.0"
Response
--------
2878
C:\>STAF staf1e PROCESS LIST
Response
--------
Handle Command Start Date-Time End Date-Time Return Code
------ ------- ----------------- ------------- -----------
2878 top 20110726-12:30:43 <None> <None>
C:\>STAF staf1e PROCESS STOP HANDLE 2878
Response
--------
C:\>STAF staf1e PROCESS LIST
Response
--------
Handle Command Start Date-Time End Date-Time Return Code
------ ------- ----------------- ----------------- -----------
2878 top 20110726-12:30:43 20110726-12:31:11 9
C:\>STAF staf1e PROCESS FREE HANDLE 2878
Response
--------
C:\>STAF staf1e PROCESS LIST
Response
--------
C:\>
Or, note that you can run top using its -b (batch mode) option in which case
then you don't need to use xterm or export the display to run it. I'm not
familiar with seagull but perhaps it has a similar option. For example:
C:\>STAF staf1e PROCESS START SHELL COMMAND "top -b"
Response
--------
2901
C:\>STAF staf1e PROCESS STOP HANDLE 2901
Response
--------
C:\>
Here's a sample STAX job that uses a <stafcmd> to submit a PROCESS START
request without the WAIT option to start the top command using xterm and export
the display, and returns the STAF process handle for top in the result (since
it did not wait for top to complete), Then it delays a while and submits a
PROCESS STOP HANDLE request to stop top.
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE stax SYSTEM "stax.dtd">

waitTime = '5s'

<!-- Delay while top runs -->
<stafcmd name="'Delay for %s' % (waitTime)">

</stafcmd>

Here's another sample STAX job that runs the top command on a remote a Linux
machine using xterm and exporting the display. It uses a timer element to run
the top command for a specified duration and then gets top sdtout output.
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE stax SYSTEM "stax.dtd">
<stax>
<defaultcall function="Main"/>
<function name="Main">
<sequence>
<script>
machine='staf1e' # Replace with your machine host name or IP address
duration = '10s' # Duration to run top
</script>
<log message="1">'Starting top...'</log>
<timer duration="duration">
<sequence>
<process name="'Run top'">
<location>machine</location>
<command mode="'shell'" shell="'xterm -title %T -e /bin/sh -c
%X'">'top'</command>
<title>'top'</title>
<env>'DISPLAY=:0.0'</env>
<stdout>'/tmp/top.out'</stdout>
<stderr>'/tmp/top.err'</stderr>
<returnstderr/>
</process>
<if expr="RC != 0">
<log message="1">
'Error running top. RC: %s, STAFResult: %s, Stderr: %s' % (RC,
STAFResult, STAXResult)
</log>
</if>
</sequence>
</timer>
<log message="1">'top is done after running for %s' % (duration)</log>
<!-- Get the contents of top's stdout.
If you don't want top's stdout output, don't do this and remove the
stdout element in the above process element. -->
<stafcmd name="'Get top stdout'">
<location>machine</location>
<service>'FS'</service>
<request>'GET FILE /tmp/top.out'</request>
</stafcmd>
<if expr="RC == 0">
<log message="1">'Output from top:\n%s' % (STAFResult)</log>
<else>
<log message="1">
'Error getting top stdout file. RC: %s, Result: %s' % (RC,
STAFResult)
</log>
</else>
</if>
</sequence>
</function>
</stax>

Subject: [staf-users] how to deal with command like top in STAX
________________________________
Hi:
I use STAX to start up seagull to test diameter protocol. But seagull
will keep flushing the screen and output the result. When I use STAX to start
seagull, it reports keybaord error. And I tried "top" command to see whether
STAX could start "top" frontend, and it also reports error. Though I do not
need the realtime monitoring result of seagull output on the screen, but I hope
to find a way to start up seagull and stop them.
Though I could put seagull to run in the background, but I could not stop
that by terminate the job on STAX right? Could you kindly tell me how to deal
with the commands like seagull or "top" which needs to reflushing the screen
again and again, if let the process run in frontend, or how to stop them in
STAX, if let them run in background. Thank you in advance.
