Wei-Chiu Chuang commented on HDDS-11341:
----------------------------------------
Much of this issue’s scope appears to have been implemented by HDDS-15352 ([PR
#10337|https://github.com/apache/ozone/pull/10337]). The Datanode Decommission
and Maintenance dashboard includes replication queues, inflight tasks, EC
reconstruction command rates, supervisor task status and completion rates, and
replicator byte-transfer rates and latency.
Some EC observability gaps remain:
* Datanode reconstruction totals and failure counters from
{{ECReconstructionMetrics}}.
* Client reconstruction totals and failures from {{XceiverClientMetrics}}.
* SCM EC replica deletion, create/delete timeout, and partial reconstruction
“none overloaded” counters.
* EC reconstruction bytes, in-progress tasks, and latency metrics requested in
HDDS-17167.
Suggest reviewing the existing dashboard against this issue’s acceptance
criteria, then either narrowing this issue to the remaining gaps or closing it
and tracking those gaps in focused follow-up issues.
> Add Grafana dashboard for HDDS health and replication progress

> Key: HDDS-11341
> URL: https://issues.apache.org/jira/browse/HDDS-11341
> Project: Apache Ozone
> Issue Type: Improvement
> Components: Ozone Dashboards
> Reporter: Ethan Rose
> Priority: Major
>
> Add a Grafana dashboard to show information about datanode health, ongoing
> and pending replication and reconstruction tasks, and the amount of data
> being moved between nodes due to these tasks. This board will be useful to
> monitor during disk failure, node failure, node decom, and maintenance.
> SCM replication manager likely has a lot of the metrics for ongoing tasks
> already. We may need to add more metrics to datanodes to monitor tasks that
> are ongoing (not just those that are queued) and the amount of data being
> moved. I think some datanode command queue and handler related metrics are
> unused as well and those can be checked/removed/updated as part of this PR.
