Hi all,
I've finally finished implementing an interface for generating
customized graphs.
A patch against Ganglia 3.0.2 is attached (it should probably work with
3.0.3 as well). You can also grab it at http://wtf.ath.cx/custom_graph.diff
I suspect IE won't like the JavaScript in this one, but I didn't really
dig into that.
Feedback is most welcome!
Cheers,
Alex
