Description

There are some minor issues in the RBD image detail dashboard added in https://tracker.ceph.com/issues/44623
  • The `I/O Bytes per second panel`: the read and write legend should be exchanged
  • The title `I/O Bytes per second panel` might be renamed to a more general term: Throughput
  • `instance`(localhost:9283 in the example below) in legends is not necessary.
  • Typo: `Averange` -> `Average`

e.g. Read some data from a RBD image:

bin/rbd bench --io-type read --io-size=64K rbd/a
