> In our production clusters, we have seen multiple cases where some of the
> wals are lingering in zk replication queues for months and we have no insight
> into it. Recently we fixed one case where wal was getting stuck if it is 0
> size and from old sources. HBASE-25536. It would be helpful if we can have
> some metric which will tell us the age of oldest wal and we can add an alert
> for monitoring purpose.
