Ceph

All the images in `perf dump` of the rbd-mirror daemon in Octopus (but not in Nautilus) have an invalid name.

What you expect to have in the perf dump:

$ ceph daemon /var/run/ceph/ceph-client.rbd-mirror.[...].asok  perf dump
{
[...]
    "rbd_mirror_image_test/test--1": {
        "replay": 0,
        "replay_bytes": 0,
        "replay_latency": {
            "avgcount": 0,
            "sum": 0.000000000,
            "avgtime": 0.000000000
        }
    },
[...]
}

What you actually have in the latest octopus release:

$ ceph daemon /var/run/ceph/ceph-client.rbd-mirror.[...].asok  perf dump
{
[...]
    "rbd_mirror_image_-0x55cbc7d63c20": {
        "replay": 0,
        "replay_bytes": 0,
        "replay_latency": {
            "avgcount": 0,
            "sum": 0.000000000,
            "avgtime": 0.000000000
        }
    },
[...]
}
