[hobbit] Graphing iostat on Linux systems?

[Husemann, Harald]

Hi Martin,

in our setup, we have a complete copy of the bb-hosts file on all 
clients in $BBCLIENTHOME/etc, which we use to control which external 
client script should run on which client.
We have pre-compiled clients for all systems on the Hobbit server, 
including all config files, which are stored as tarballs.
When I'm setting up a new client, I just add the appr. lines in the 
server's bb-hosts file, copy the new bb-hosts to the tarballs (we're 
planning to use something like rcsvi in the future to automate this 
step), and then execute a script on the server which uses scp and ssh to 
contact the new client, copy the tarball, untar it and start the client.
Hope this sheds some light on the preamble, :-).
