when I try to view storage resources in horizon's "resource usage" tab we get no data available message.
looking at horizon log I see that we are getting an error but can't find anything in ceilometer to suggest why we fail to show the info.

Could you attach a screenshot or confirm the resource name? It's not clear to me if you're talking about the Stats drop down and graph, or one of the tabs data which were later removed (see bug 1249279).
