Sure.

iostat output is below. This particular example is in five second intervals but the script will take in a variable that allows the user to specify whatever time interval in seconds they prefer.
Code:
-bash-3.00$ iostat 5 -x -t

This is what I'd like the cpu statistics to look like:
Code:

07/05/10 21:34:21,0.40,0.00,0.60,0.10,0.00,98.90
07/05/10 21:34:26,0.50,0.00,0.30,0.20,0.00,99.00

And the device stats:
Code:
date/time,rrqm/s,wrqm/s,r/s,w/s,rsec/s,wsec/s,avgrq-sz,avgqu-sz ,await,svctm,%util
07/05/10 21:34:16,hda,0.00,3.89,0.11,0.34,5.33,33.92,87.03,0.28,629.52,2.97,0.13

I can probably figure out how to use sed or awk to parse the strings, honestly my confusion stems more from the logistics of how to take the output and manipulate it in rt. I can run two separate instances of iostat, one which pulls cpu stats (iostat -c) and one which pulls device stats (iostat -d), but it is preferable to parse the output from one.
