In other words, being able to dynamically add and remove metric module configuration. Currently gmond can't handle adding or removing metric configuration on the fly. It reads all of the configuration at startup and creates an internal list of metrics and associated data. Gmond depends on that internal list for everything and changing it on the fly would cause major problems. In order to do what you are suggesting, which I think would be great BTW, the whole mechanism for tracking metrics and metric data will have to be reworked. This can certainly be done, but it will take some well thought out design and coding.
