Shell Programming and Scripting

Hi,

I am creating monitoring scripts in HP unix for that i need CPU utilization and memory utilization in HP unix.

for CPU utilization i am using TOP command
for Memory utilizaion i am not able to use glance command in scripts.

means i am not able to redirect and stop.

apart from glance command is there any command to get mem utilization.
or any calculation there.

Please suggest me.

Regards,
Siva

It is possible to run glance from a script. See "man glance" for the command line options.
Unfortunately it will not do just one iteration but it is quite easy to fish out the figures you want and they are more reliable than those from "vmstat".

One example: The "-m" switch is the same as typing "m" in interactive mode. In my version the "-iterations 0" actually becomes "-iterations 2" because of a limitiation in "glance". The "-f myglancelog" writes the output to a file called "myglancelog". the "1>/dev/null" disposes of the normal screen output.

Code:

glance -m -iterations 0 -f myglancelog 1>/dev/null

BTW. For cpu utilisation I'd use "sar".

If you are doing serious realtime monitoring rather than the odd snapshot there are pay products from HP.
