gmond is not required for gmetad to work properly - however,

- most people do want the gmond agent on their gmetad host anyway

- the default configuration I have provided assumes that a gmond 
instance is running on the same host as the gmetad, this allows the 
Ganglia packages to work immediately with no manual configuration effort

I haven't personally tested in zones, I know someone else who has tested 
it and found it doesn't work, the agent needs to be tweaked a little bit

see above note about dependency

Have you modified the configuration files, or are you using the 
configuration files I provide?

What is the data_source line in gmetad.conf?

Do any of the Ganglia pages work?

Try and wget that URL to a file, and look at what is in the file - maybe 
PHP is spitting out error messages instead of a PNG file

That should probably work, but do make sure your apache2 has PHP support
