[hobbit] Graphing iostat on Linux systems?

[Martin Flemming]

Hi, Harald !

thanks for the hint with drdb !

Hmm, .. but dont't understand your "preamble",
if i use your script, it seem's that the script think,
that it's serverside-script ... ;-)

[it-hobbit2] /usr/lib/hobbit/client # bin/bbcmd ext/new_linux-iostat.pl
2009-04-06 23:56:55 Using default environment file /usr/lib/hobbit/client/etc/hobbitclient.cfg
2009-04-06 23:56:55 Cannot load bb-hosts, or file is empty
Not running on it-hobbit2...

[it-hobbit2] /usr/lib/hobbit/client #

.. but it isn't one ...

What's is missing in my enviroment ?


thanks & cheers,

 	martin
