Hi all,

I'd like to use iostat for performance monitoring, and include its
output in the Hobbit pages.
I've found an old post about it, but it seems that the URL mentioned
there (http://www.docum.org/twiki/bin/view/Hobbit/LinuxIostatGraphs) is
no longer valid.
Any ideas where I can get it?

For further reference, I added some Redirect statements so all references to 
twiki and/or Hobbit are redirected to /foswiki/bin/view/Xymon
