I am looking for a script to run the top command

[John Jimenez]

I looked through the favorite sysadmin scripts and found this one. but this does not seem to be showing be the right info. I am not even really sure what it is telling me? Do anyone know of one that will give me something more similar to the to the top command? I took this command and modified it to run every 20 minutes.

UNIX95= ps -e -o "vsz pcpu ruser pid stime time state args" | sort -rn |head -10

Hi John,

I didn't get your requirement. If your idea is to capture the top output into a file, then you can use -f option of top to dump it into file. For ex.,

top -s 5 -d 10 -f top.out

will print 10 top sessions at the interval of 5 seconds.

You may want to consider looking at Glance|gpm. It will give you an extensive output with excellent online help.

Yes I want to echo it to a report. Especially things running at night. Thanks I will try this.

Hi:

The script reports the "top-10" processes in terms of memory (core) consumption. The output is sorted in descending size -- largest first.

The option 'UNIX95' is set *only* for the command line -- the 'ps' command. This option is also known as 'XPG4' behavior. The various 'ps' options (e.g. vsz, pcpu, etc) are explained in the 'ps' man pages. The beauty of using the '-o' option is that *you* can choose how you want your output to look and what it should contain.

As Sri already noted, 'top' has a '-f file' option to direct its output into a file that can be parsed.

Regards!

Attaching a series of sar scripts that collect information for a period of time determined by you.

This follows on Paula's suggestion.

I will be updating/improving this package in the next few weeks, but it works pretty well now.
