> There can be situation when the cluster is not able to talk to peer cluster
> ZK, in that case, yes the logQueue will be accumulating but without digging
> into the logs, we cannot know what's the reason of loqQueue getting
> accumulating on the source.
> Since the replication source doesn't even start the shipper in this case, it
> is good to have a dedicated metric if the RS cannot talk to the peer's ZK at
> all.
