After setting up cluster replication in Hbase, we want to monitor replication lag between clusters.
> status 'replication' : Gives output like
SOURCE: PeerID=sep᐀node, AgeOfLastShippedOp=0, SizeOfLogQueue=0, TimeStampsOfLastShippedOp=Fri Aug 02 18:24:18 IST 2019, Replication Lag=346
SINK : AgeOfLastAppliedOp=0, TimeStampsOfLastAppliedOp=Tue Jul 30 17:45:24 IST 2019
Can anyone help what that Replication Lag is actually? How is calculated in terms of available metrics ?
Looked at the replication metrics. Didn't match any as specific as replication lag which Hbase provides.
We are having the same question here. Nothing useful on available metrics on CDH 6.2.0
