I'm looking at the "nova host-describe devstack-grizzly" in the user-guide [1], I'm not sure I understand what the "total", "used_max" and "used_now" values mean in the memory_mb context. I expect the "total" to have the highest value, and the "used_max" to have higher value than "used_now" but that's not the case. Could someone shed some light here?
