used the top with cron

Isaac_4 — Thu, 14 Mar 2002 20:41:25 GMT

I try to put the top in the cron, the error that I recived in mail root is.

Sorry, I need to know a more specific terminal type than 'unknown'.

You probably need to modify the shell script you are running in the cron.

try:
#!/bin/sh
TERM=vt100 ; export TERM
top -f > /foo/top.out

Top is supposed to run to a tty. It would better if you were trying to collect system performance information to use the measure agent of glance or the output of sar. There are many posts on this.

If you are using top in a cron job, you probably want to specify the '-f filename' option as well so that output gets written to a file.

Something like:

top -d 5 -n 30 -f /tmp/filename

will run through 5 iterations of top with the top 30 processes of each iteration.

oops!

There should not be a redirect in my previous post.

top -f /foo/top.out

That will should work.

Actually, there is a way. Inside your cron script, do a top -f /var/tmp/tfile and then mail your tempfile.

You should of course, create a temp file name, mail it, and then remove the temp file but top -f filename is the key. Top will run once and exit.
