Siddharth Wagle commented on HDDS-961:
--------------------------------------
[~nandakumar131] Shouldn't datanode report these as metrics itself? The metrics
collection/visualization system like Prometheus could do the aggregation for us?
Alternatively, could we include completion time in the CommandStatus object?
Should we create something like SCMCommandMetrics per command type and it
stores these global counters for the average completion time of the specific
command?
> Send command execution metrics from Datanode to SCM

> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Components: Ozone Datanode, SCM
> Reporter: Nanda kumar
> Priority: Major
>
> The CommandHandlers in datanode calculates and tracks the time taken to
> execute each command that is sent by SCM. It would be nice to report these
> values to SCM so that we can build average time, std dev etc for those
> operations.
