Sorry, didn't meant to hijack your thread :-) It might still be useful to discuss the simpler case of tracking top clients/top objects (i.e. just native RADOS concepts) with an LRU table of stats (like Sage described) as a simpler alternative to my custom-querying proposal. I'm going to write a blueprint for the the custom query thing anyway though, as I'm kind of hot on the idea, though don't who/when will have time to take it on as it's a bit heavyweight. John
