Hi, we have a lot of pools which contain rbd volumes containing VM images. I want to know which volume causes most traffic. It's easy to determine which pool causes traffic, for example: # ceph osd pool stats [...] pool abaswebtest id 56 client io 3372 kB/s rd, 10557 kB/s wr, 1303 op/s How to dig further? As far as I know, the knowledge of which objects map to a specific rbd volume is hidden somewhere inside rbd. Is there a way to summarize per-volume I/O for a given pool? TIA Christian -- Dipl.-Inf.
