I'm curious. Is installing ganglia part of a class assignment? Does
everyone in your class install it or are certain people assigned different
tasks?

You are installing an old version of the client v1.0.3 (I think). Version
1.0.4 does not have that problem. You can download it from...
http://ganglia.sourceforge.net/
Let me know if the update does not solve your problem (but I'm pretty
certain that it will).

Yes, you need to install gmond on every node on your cluster including the
web server.
NOTE: If you don't want the web server machine to show up in the
list of machines then start gmond with the "--mute" flag. This will make
the gmond on the web server listen and process traffic without
multicasting it's information.

The ganglia PHP/RRD Web client only needs to be installed on your web
server and no where else.

All the documentation for ganglia is at
http://ganglia.sourceforge.net/docs/
Good luck!
