This topic has come up on the list a couple of times, but I don't think I've ever heard a definitive answer.
I really need the ability for the NCV module (or a different module) to create multiple rrd files using data from a single test, just like the way the do_disk rrd handler works. Over the last month I have been working to get a lot of my networking equipment monitored and graphed using devmon, and there are many situations (such as concurrent sessions per virtual server on my load balancer) where the addition of a new monitored parameter (i.e adding a new virtual server) to the exisiting test will cause havoc for the ncv rrd handler. Is there any chance that this kind of functionality will make it into Hobbit? It'd be cool to have an NCV module that can handle both cases, or an additional NCV module to produce multiple rrd files and works alongside the traditional one.
