> Key: HDDS-1890
> URL: https://issues.apache.org/jira/browse/HDDS-1890
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: Ozone Datanode
> Affects Versions: 0.5.0
> Reporter: Shashikant Banerjee
> Priority: Major
> Labels: Triaged
>
> Following metrics have been identified to be incorporated inside containerStateMachine in order to measure and monitor the data pipeline performance in datanode:
>
> |containerDbAvgLoadLatency|Avg time to load a container db|
> |avgWriteStateMachineDataLatency|Avg time to write stateMachine Data|
> |stateMachineCacheMissRatio|Ratio of stateMachine machine cache misses to total no of readStateMachine calls|
> |avgTransactionalLatency|Avg transactional time for a client request inside the stateMachine(i.e, time from startTransaction call till applyTransaction of the request completion)|
> |avgContainerDbReadLatency|Avg Rocks Db write latency during putBlock|
> |avgContainerDbWriteLatency|Avg Rocks DB read latency during getBlock|
> |avgCommitChunkLatency|Avg time taken to rename a chunk file|
> |numNotifyNoLeaderCallCount|This indicates how many times stateMachine has been notified of no leader for extended period of time|
> |numNotifySlownessCallCount|Number of times a follower is notified to be slow to the stateMachine|
