Did somebody say, "undocumented feature" ?
gmetad and the web front-end control the "grid" stuff - this is a new
feature addition as of 2.5.2, which was released maybe a little more
quietly than it should have. I don't even know if these changes have been
documented.
But, for the record (take all this as "a bunch of stuff not from the guy
who actually wrote these features" - I might not be 100% accurate):
The two settings you'll want to change are "gridname" (for the proper name)
and "authority" (for the URL).
The defaults are, respectively, "Unspecified" and
"http://$HOSTNAME/ganglia-webfrontend.";
Note that the "Grid" part is actually defined in one of the PHP scripts
(pretty sure it's conf.php - grep for it and I'm sure you'll find it).
It's described as the default name for a gmetad source, I believe.
At the abstract level, "grid" is defined as the "cluster of clusters"
level. The features that have been added to 2.5.2 make it possible for the
web front-end to pull data from more than one gmetad source (basically, to
cluster web front-ends!).
Useful if you have a lot of clusters, I guess. :)
