I'm not sure if this is related but I finally put my DSO modules on git.
https://github.com/pdt256/gmond_python_modules
I noticed a problem in my "patch against trunk r2355 v2" for custom graphs
using "+" showing up on the cluster view...they don't show up at all :) I
will get a new patch created when I get a chance.
Also, I don't think the "+" or "*" options are even included in the
meta/grid view. I did not have a need for them yet but I can add that
feature if this custom graph patch will get accepted upstream.
Does any of this make sense?
