> Currently, the Roles table in the webui displays allocation and quota guarantees / limits. However, quota "consumption" is different from allocation, in that reserved resources are always considered consumed against the quota.
> This discrepancy has led to confusion from users. One exampled occurred when an agent was added with a large reservation exceeding the memory quota guarantee. The user sees memory chopping in offers, and since the scheduler didn't want to use the reservation, it can't launch its tasks.
> If consumption is shown in the UI, we should include a tool tip that indicates how consumed is calculated so that users know how to interpret it.
