------------------------------------

             Summary: Add metric for age of oldest wal in region server replication queue.
                 Key: HBASE-25500
                 URL: https://issues.apache.org/jira/browse/HBASE-25500
             Project: HBase
          Issue Type: Improvement
          Components: metrics, regionserver, Replication
            Reporter: Rushabh Shah
            Assignee: Rushabh Shah
             Fix For: 3.0.0-alpha-1, 1.7.0


We have seen cases recently where we have wal from 2018 timestamp in our recovered replication queue. We came across this un replicated wal while debugging something else. We need to have metrics for the oldest wal in the replication queue and have alerts if it exceeds some threshold. Clearly 2 years old wal is not desirable.
