OT: Unix - performance tuning (vmstat 5)

[CHAN Chor Ling Catherine (CSC)]

Hi Unix Gurus,

I submit a job to monitor the CPU utilization etc every 15 mins using the
command vmstat 5.

How do I kill the submitted unix process of the batch job ? 

I tried to kill the submitted process using a batch job using the following
command :
var_pid=`echo $var_grep_vmstat | (read u v w x y z; echo ${v} )`
kill $var_pid

This works if the output is 
$ ps -ef | grep vmstat
   orahrms 11271 11263  0 17:30:00 ?        0:00 vmstat 5
   orahrms 11612 11576  0 18:50:53 pts/11   0:00 grep vmstat

If the output is as below, the program will not work 
$ ps -ef | grep vmstat
   orahrms 11612 11576  0 18:50:53 pts/11   0:00 grep vmstat
   orahrms 11271 11263  0 17:30:00 ?        0:00 vmstat 5

Please help. Thanks in advance.

Regds,
New Bee
