Hi Jochen,
I agree with your assessment, I think most everything is working except for the
graphs. I am using rrdtool as the graph engine, here are the settings from my
php.conf file:
$conf['gweb_root'] =
"/opt/freeware/apache2/htdocs/ganglia";$conf['gweb_confdir'] =
"/var/lib/ganglia-web";$conf['gmetad_root'] =
"/var/lib/ganglia";$conf['rrdtool'] = "/usr/bin/rrdtool";$conf['rrds'] =
"${conf['gmetad_root']}/rrds";

These all look pretty broken

But that's a usefull hint - we have data. So, your clients
send data to gmetad and the webfrontend can display it.
So "just" the generation of graphs is broken.
Which graph_engine do you use?
# Graph Engine to use
$conf['graph_engine'] = "rrdtool";
Do you have rrdtool installed and where? On Linux the
default config is:
# Leave this alone if rrdtool is installed in $conf['gmetad_root'],
# otherwise, change it if it is installed elsewhere (like /usr/bin)
$conf['rrdtool'] = "/usr/bin/rrdtool";
You can add &debug=3 to the graph.php call and it will
display the rrdtool command it calls. Try that in a shell
and see what it says.

Sometimes we also have messages in the apache log, but probably
not this time.
