This is true. You can actually add anything that you want to the metric definition in your module. If Gmond does not recognize the extra elements in the definition, it will simply add the key/value pair as <extradata/> in the XML that is produced by gmond. Both gmond and gmetad will ignore extra data and just continue to pass it through in the XML. At that point you could write a specialized graph module in the web front end that does understand the extra data tags in the XML and reacts to them appropriately.
