I am trying to figure out if there is a way to get more meaningful chargeback reports than what comes out of the box with vFoglight 6.7.1.  If I use tiered flat rate I am going to have to create too many tiers and add-ons (and spend way too much time assigning them).  If I use MRU I get closer to what I am seeking, but I am not sure how much value storage I/O adds.  I need to account for storage costs, but I need to be able to charge per GB, not IOPs.  Has anyone figured out a way to dynamically charge for things like the number of CPUs, RAM, and storage (by the GB)?  It doesn't seem practical to create add ons for the many configurations you end up with when you have hundreds or thousands of VMs.

In short, I would like to be able to set a cost per vCPU, GB of RAM, and GB of storage and be able run that against my VMs.  If using MRU I would like to be able to replace storage I/O with storage space utilized, or at least add it as an option.  If there is a way to make add ons dynamic that would work, too.

Thanks
