Brad, I did have a play but I have been distracted by other work. What I did not find was the way to integrate the just created custom graph definitions into the normal cluster and host views.
I have some more time now - I would be happy to look at it again, because that kind of functionality is something we need. As an aside, one of reasons I have not yet pushed some of our local stuff here back into ganglia is because we were brutal with the PHP tree and did not keep our changes modular and reversible. And as for ganglia "improvements" not getting into the source tree, I see a couple of problems as it stands now. 1) The current code administrators are doing other work, and anyway, they have been doing ganglia for ages - the drive to keep dicking around with it has gone. 2) Using patches during an evaluation or test phase? Not everyone is familiar with that, and not everyone has a test ganglia environment, and not everyone event wants to build, look and test. They just want to get the best good one. Even *I* don't want to dick around with patches. 3) Many have hacked ganglia and the php in lots of places, so patches may require some effort to get right. So they don't bother. Guess what? the people you really want feedback from are the ones who have a customised ganglia. 4) You have good features but a hacked ganglia? Untangling the patch for a single feature may be too fiddly for them to even bother. (this is my case). 5) Ganglia has branched. It is not used just Linux HPC. Some proposed changes may be of no interest to some, and maybe it would break something they do. What do we do? - For changes that affect the PHP only, we can test the modified ganglia very easily. We provide the change with its full PHP tree. We let users know that they can drop this PHP tree right on their live ganglia-server under a different directory, say "test". They can test using their real clusters. No production impact. No thinking needed. No Risk. - I have really wanted an internet accessible ganglia with my mods on it to enable an easy demo of the customisations with 0 effort. Maybe we should make one, and this becomes the new features demo site.
