CPU/Memory utilization

hi guys
I just want to know how to get the cpu/memory utilization of a running script?
Well i know that I can use the sar command but it shows the whole system's statistics.
Is it possible to get the stats of a single scirpt or a single running service?

Have you tried using sar with some flags?

Quote:
-r Report memory and swap space utilization statistics
-x { pid | SELF | ALL } Report statistics for a given process. pid is the process identification number. The SELF keyword indicates that statistics are to be reported for the sar process itself, whereas the ALL keyword indicates that statistics are to be reported for all the system processes. All these statistics cannot be saved to a file. So this option will be ignored whenever -o option is used. Specifying multiple -x pid parameters on the command line will look at multiple independent processes. At the present time, no more than 256 processes can be monitored simultaneously.
-X { pid | SELF | ALL } Report statistics for the child processes of the process whose PID is pid . The SELF keyword indicates that statistics are to be reported for the child processes of the sar process itself, whereas the ALL keyword indicates that statistics are to be reported for all the child processes of all the system processes. All these statistics cannot be saved to a file. So this option will be ignored whenever -o option is used. Specifying multiple -X pid parameters on the command line will look at multiple independent processes. At the present time, no more than 256 processes can be monitored simultaneously.

Otherwise maybe you can see what you're looking for in top?

LOL...well that makes a difference.

If you don't have glance...use top.

You can navigate through the pages using:

Quote:
j Display next screen if the current screen is not the
last screen.

k Display previous screen if the current screen is not
the first screen.

t Display the first (top) screen.

w Display individual CPU information in place of
individual process information and vice versa.
Just scroll through until you find the process.

CPU TTY PID USERNAME PRI NI SIZE RES STATE TIME %WCPU %CPU COMMAND
