4/27    I wrote a little shell script to collect iostat data:
        #!/bin/bash
        DATE=`date +%m%d`
        DATADIR=/var/tmp/user
        OUTPUTFILE=$DATADIR/$DATE.out
        while true
        do
        date; /usr/bin/iostat -x 1 > $OUTPUTFILE
        done

        Is there a better way to do this? Open source tool perhaps?
        \_ It's the easiest way. If you want to go fancy, Graphite is
           pretty nice for app level stuff.
           \_ Wow, this Graphite?

              Do you have it installed?
