Summary: [Docs] Datanode metrics
Key: HDDS-14806
URL: https://issues.apache.org/jira/browse/HDDS-14806
Project: Apache Ozone
Issue Type: Wish
Components: documentation
Reporter: Wei-Chiu Chuang
Datanode has a lot of metrics that are useful to monitor and troubleshoot
system performance.
The metrics objects are instantiated by DatanodeStateMachine, and include:
* NettyMetrics
*
ECReconstructionMetrics
*
ReplicationSupervisorMetrics
* MeasuredReplicator (pullReplicatorWithMetrics, pushReplicatorWithMetrics)
*
ReplicationSupervisorMetrics
*
DatanodeQueueMetrics
and also:
* BlockDeletingServiceMetrics
*
BackgroundVolumeScannerMetrics
*
VolumeHealthMetrics
*
VolumeInfoMetrics
*
CommandHandlerMetrics
It would be great to include every single metric item in a reference document.
