I was experiencing a similar issue as given in http://www.mail-archive.com/ganglia-general@lists.sourceforge.net/msg05400.html
My error was that I had the web front-end (conf.php) using the gmetad xml_port when in fact it should be using the interactive_port. It was hard to diagnose. Telnetting to the xml_port would show all the hosts. Sometimes the web front end would show partial information and sometimes it would show all information. Php errors of the form were produced: [Tue Dec 21 15:47:09 2010] [error] [client 127.0.0.1] PHP Notice: Undefined index: cpu_num in /usr/share/ganglia/functions.php on line 179, referer: http://localhost/ganglia/ [Tue Dec 21 15:47:09 2010] [error] [client 127.0.0.1] PHP Notice: Undefined index: load_one in /usr/share/ganglia/functions.php on line 184, referer: http://localhost/ganglia/ [Tue Dec 21 15:47:09 2010] [error] [client 127.0.0.1] PHP Notice: Undefined index: boottime in /usr/share/ganglia/host_view.php on line 88, referer: http://localhost/ganglia/ [Tue Dec 21 15:47:09 2010] [error] [client 127.0.0.1] PHP Notice: Undefined variable: c_metrics in /usr/share/ganglia/host_view.php on line 127, referer: http://localhost/ganglia/ I hope this helps somebody else.
