Getting CPU Usage
For analysis, I need to gather CPU usage from say 1:00 PM to 2:00 PM every 10 seconds on a given day. I heard this can be done with awk, but my UNIX is kind of rusty.

Try running this command at 1:00 PM.
Code:
mpstat 10 60 >> /path/to/logfile &

Hello,

In a Linux box you can get {1,5,15} mins CPU load averages from /proc/loadavg special "file" with the help of "awk", for example:

Quote:
$ DATE=`date +"%Y-%m-%d %H:%M:%S"` cat /proc/loadavg | awk ' { print ENVIRON["DATE"] " - " $1 "/" $2 "/" $3 }'
2006-05-01 00:45:39 - 0.33/0.26/0.24
You can add this simple one-liner to a cronjob and redirect the output to a log file...
