Hi bondbhola,
thanks for responding! Custom reports let me select the "Volume Used Capacity" for the deleted volumes, which I take it was the last update of the capacity used before the time of deletion. What I need is not the size when the volume was deleted but at some earlier time, basically a snapshot of the environment on a given day, ideally as a list: 'here are all the volumes that existed on day X and the used capacity for each of these volumes on that day'.
I've tried to get at the data in my lab using
dfm graph -s <365DaysInSeconds> -e -<364DaysInSeconds> volume-usage-1y <objectname>
however it complains ("no such object") when I use object IDs listed in the volumes-deleted report, which could be because of my lab environment or it could be because DFM doesn't retain this data for deleted volumes. I'm wondering if I'm going about this the wrong way or if the data I need isn't in DFM.
Cheers,
--Jon
