Subject [jira] [Created] (HBASE-16302) age of last shipped op is not representative for multiwal
Date Thu, 28 Jul 2016 22:41:20 GMT
Ashu Pachauri created HBASE-16302:
-------------------------------------

             Summary: age of last shipped op is not representative for multiwal
                 Key: HBASE-16302
                 URL: https://issues.apache.org/jira/browse/HBASE-16302
             Project: HBase
          Issue Type: Improvement
          Components: Replication
            Reporter: Ashu Pachauri
            Assignee: Ashu Pachauri


Replication exports metric ageOfLastShippedOp as an indication of how much replication is
lagging. But, with multiwal enabled, it's not representative because replication could be
lagging for a long time for one wal group (something wrong with a particular region) while
being fine for others. The ageOfLastShippedOp becomes a useless metric for alerting in such
a case.

An example improvement can be providing age of last shipped op per wal group.
