Hello,

This is happening because your are using nmon in interactive mode switch it to make something like one snapshot for 1 second and exit (check nmon -h).

Thanks for the replay.
I have tried creating a script on server B which included as

Code:
export NMON=m
 
nmon -MB -s1 -c1 > nmon_now.txt

a=`grep -b Paging nmon_now.txt | awk '{print $12}' | cut -c 1-4`
b=`grep -b File nmon_now.txt | grep -v pages/sec | awk '{print $13}' | cut -c 1-4`
c=`grep -b Scans nmon_now.txt | awk '{print $10}' | cut -c 1-4`
d=`grep -b Cycles nmon_now.txt | awk '{print $8}' | cut -c 9-11`
e=`echo " $b + $c + $d " | bc`

echo " % Comp    = " $e
echo " % Noncomp = " $a
echo " % Client  = " $a

then I ran
Code:
ssh server B /home/asdf/above_script.sh

passwd given
it excuted that script on server B but i got null value as a result.


warm regards,

Sorry for asking but currently I don`t have access to any AIX node(will have later this week) so I cannot test it but:

Does

Code:
ssh server_B 'nmon -MB -s1 -c1'

work normal?

If it works normal try to execute the script in debug mode/ run it locally to test it out - output will be helpful.

note: for ksh you can put

Quote:
set -x
In the beginning of you script or use

Code:
ssh server_b  'ksh -x /home/asdf/above_script.sh'

A couple of things to think about:

Run nmon or 24 hours on a node. Use something like:
Code:
$NMON_EXECUTABLE -F $WORK_DIR/$NMON_LOG_FILE -s $DELAY -c $COUNT

Run the above from cron, with:
/home/unxsa/bin/collect_nmon_perf_data 898 96

DELAY=898 COUNT=96

Then use nmon analyzer to produce reports.

This doesn't give you instant monitoring of course.

IIRC you start nmopn in daemon mode with the "-F" parameter. Without it nmon will always come out in interactive mode, regardless of where you direct its output.

I hope this helps.
