Monitoring a process

[Sanjiv Sharma_1]

Hi,

Is there any utility( command, script or tool) which I can use to monitor a particular unix process in HP-UX 11.11?

What I want to do is to keep track of a particular process and wants to find out how often is it in run mode and how often it went to sleep.

Thanks,

I think there is no such built-in function. But it's pretty easy script to write that will parse the "ps" output.

"man ps" you'll see the filed names and probably you'll have to set UNIX95 variable on.

You can try with a script as,

#!/bin/ksh
# monitor.ksh
PID="9889"
STIME=120 # Sleep time in seconds
while [ 1 ]
do
ps -efl | grep $PID >> /tmp/monitor.log
sleep $STIME
done

# chmod u+x monitor.ksh
# ./monitor.ksh &
# tail -f /tmp/monitor.log

will give details.

Hy,
you can try with Glance product and the extract command (see man extract) combination.
The metric ones that interests to you would have to be:

PROC_PROC_ID
PROC_RUN_TIME
PROC_SLEEP_WAIT_PCT

Actually, you can deduce the sleep versus run state by the starting time and the amount of CPU consumed. Programs can change states (there are many, many other states) dozens of times per second. Processes will not be running while waiting on I/O (a few milliseconds) or waiting on a semaphore flag, or waiting on a system call. The ps command can give you specifics about start time and CPU consumed, so subtract CPU consumed from total time running and the result is sleep or more accurately, wait time.
