[hobbit] Iostat graphs

[Kevin.Hanrahan at novainfo.com]

You might be right...I honestly don't remember which one is on that
particular server. I have had problems getting a single I/O script to work
consistently across all our *NIX platforms (solaris, linux, and aix....maybe
SCO someday) so I am really just looking for a good I/O tool that works
cross-platform...and the graphs would be a major bonus too. Suggestions?

This doesn't look like the iostat output from the LARRD bf-iostat.sh script.
More like something from the vmio script, but not quite.

So it's quite understandable that you don't get any graphs, because this is
an input format that is simply not recognized.

If you can point me to the script you're using and some of the data you want
to graph, I'll see if I can come up with something. But much of the data
should already be available if you have the vmstat graphs (particularly the
vmstat "wa" column for how much cpu time is spent in i/o wait).
