Jitendra Nath Pandey commented on HDDS-1568:
--------------------------------------------
We should have a generic metrics2 adapter for rocksdb metrics that can be used
in SCM, OM and Datanodes.
Additionally, a Datanode will have multiple instances of rocksdb one for each
container, it should be possible to prefix the metrics with container-id.
Please also note that DN will have thousands of containers and hence thousands
of rocksdb instances, so we might have scale concerns as well.
