The information seems to indicate that you don't need the web server on the "green" cluster, but do you? I tried to set this up, although I had some difficulties. I have the admin node pulling from the head nodes on 8651 (gmetad), but I don't get my cluster names showing up. Debug output on the admin node from gmetad looks like: [Rack 1] is a 2.5 or later data stream Found a <GRID>, depth is now 1 Found a </GRID>, depth is now 0 Writing Summary data for source unspecified, metric disk_free Writing Summary data for source unspecified, metric bytes_out Writing Summary data for source unspecified, metric proc_total Writing Summary data for source unspecified, metric cpu_nice Writing Summary data for source unspecified, metric pkts_in So it knows that the source is "Rack 1", but then below it is saying "source unspecified". In the web interface I now have a grid called "unspecified" and clicking those images seems to try to redirect me to a webserver running on the head nodes (which isn't installed...) This leads back to the initial question: Do I need the PHP web interface installed on all of the "Green" clusters (as per the IBM images, above)?
