I've finally sorted out the display and eliminated unneeded metrics. Have a quick read of gweb2/cluster_view.php and gweb2/host_view.php. You will see that the "optional" graphs are loaded from CONF_DIR/default.json Then overlaid by CONF_DIR/cluster_<cluster-name>.json and finally (for the host view) CONF_DIR/host_<hostname>.json.
The first step is to find the correct CONF_DIR, it may well not be where you expect! Look in gweb2/conf_default.php and locate the lines $conf['gmetad_root'] = "/var/lib/ganglia"; ... $conf['conf_dir'] = $conf['gmetad_root'] . '/conf'; So now go to /var/lib/ganglia/conf, though of course YMMV. Have a look at default.json which specifies the graphs to include. In my case I copied it to cluster_Switches.json which will affect the cluster and host views in the Switches cluster. Change included_reports to excluded_reports and list those reports you do not want to see: "excluded_reports":["mem_report","cpu_report"] The unwanted graphs magically disappear! :-) I then stopped sending the dummy values that were only sent to keep the unwanted graphs looking nice and removed the RRD files (/var/lib/ganglia/rrds/Switches/...) and have nice clean reports.
