---------------------------------
Parent: HDDS-13616
Issue Type: Sub-task (was: Bug)
> Remove calculatePipelineBytesWritten from DN code path
> ------------------------------------------------------
>
> Key: HDDS-13613
> URL: https://issues.apache.org/jira/browse/HDDS-13613
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Aswin Shakil
> Priority: Critical
>
> _XceiverServerRatis#calculatePipelineBytesWritten_ is called everytime when
> we send a pipeline report, This method goes through all the containers to
> filter out those container belonging to a pipelineID. In a dense DN, this
> would cause a bottleneck when we send pipeline report. It would also cause a
> rippling effect as the pipeline creation will become slow and the piple
> scrubber in SCM will close this pipeline if the DN doesn't create the
> pipeline within time. The DN will consisently be in a loop to create and
> close pipeline which would make the DN unresponsive.
> This _calculatePipelineBytesWritten_ is only used by a metric in SCM an thus
> it should be removed, These aggregations needs to be done by Prometheus.
