I want to draw a graph about the use of total physical memory and virtual memory in a period of time every some interval. So I want to extract some data from the output of svmon -G command. What I want to extract is inuse memory and inuse pg space and layout will be like this as columns:

530344 28813
.. ..
.. ..
.. ..
instead of
530344
28813

Then I may load the text file to excel and draw a graph according the two columns. Could you please help to compose the
script？ Or any other good idea to do this?

1. svmon -G

size inuse free
memory 3342336 530344 2881640 34
pg space 131072 28813

work pers clnt o

in use 488799 0 41545

PageSize PoolSize inuse pgsp
s 4 KB - 260408 28813 21
m 64 KB - 16871 0

I also want to add the process numbers for some specific process during the period to the report . I may get the process number with this command.Here the number of java process is 1.

bash-3.00# ps -e|grep java|wc
1 4 26
So the report willl look like this:

533177 28808 1

don't expect them to write your whole script though.

I might be wrong but I think nmon does this.

Thanks for the reply. I have got the script done and also it seems working well.

memory.sh:

m=`svmon -G | awk '{ if ($1=="memory") my=$3; else {if ($1=="pg") my=my" "$4};
if($1=="pg") print my }'`
s=`ps -e|grep "java" |wc | awk '{print $1}'`
echo "$m $s" >> /tmp/memory.out
I use another shell to do timing execution using a infinite loop and sleep:

while true
do
/memory.sh
sleep 2
done

Feel free to give your advice if you do not think it is ok.
Also I had tried nmon. It is really a good way especially integrated with nmon analyzer. But my requirement is some what special( need the number of java process every 2 seconds). So just the script can do that.
