Re: [hobbit] Graphing iostat on Linux systems?


Ok, that explains , why it's  thinking to be server-side-script :-)

thanks,

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, :-).

 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,
