No, there is no solution for this yet. The problem is that gmond does not yet
provide a way for metrics to be dynamically defined. Every metric has to be
defined through the configuration file first. I'm sure that there a many
solutions to this problem, but nobody has stepped up to tackle this one yet. I
don't believe that this one will be a quick fix. Everything is designed around
full configuration through the config file. Solving this problem will require
some architectural redesign.
