Yes.
But, eg.
**numBytesInRemote** The total number of bytes this task has read from a
remote source.
**numBytesInRemotePerSecond** The number of bytes this task reads from a
remote source per second.
Users can easily know that these metrics units through this description,
will not be confused.
So, I think we do not need to add additional unit descriptions to these
metrics (except latency metric).
