> Key: HBASE-24350
> URL: https://issues.apache.org/jira/browse/HBASE-24350
> Project: HBase
> Issue Type: Improvement
> Components: Replication
> Affects Versions: 3.0.0-alpha-1, 1.7.0, 2.4.0
> Reporter: Sandeep Pal
> Assignee: Sandeep Pal
> Priority: Major
> Fix For: 3.0.0-alpha-1, 1.7.0, 2.4.0
>
>
> It was observed during some investigations that table level metrics for shippedBytes are always 0 consistently even though data is getting shipped.
> There are two problems with table-level metrics:
> # There are no table-level metrics for shipped bytes.
> # Another problem is that it's using `MetricsReplicationSourceSourceImpl` which is creating all source-level metrics at table level as well but updated only ageOfLastShippedOp. This reports lot of false/incorrect replication metrics at table level.
