Created attachment 847337 [details] screencap Installed RDO for Icehouse test day. Horizon says "Disk GB Hours" (see screencap).
I can reproduce this on a master checkout. Reported upstream https://bugs.launchpad.net/horizon/+bug/1267362
The issue is the category name "Disk GB Hours": what is it? a time frame? a unit to measure an amount of data?
actually, it's returned by nova: http://docs.openstack.org/user-guide/content/usage_statistics.html (at the bottom) I'm not sure, if we could find a better name for this. It's actually the same as for RAM or CPU hours
