Summary: RocksDB instance statitics register as metrics collision
Key: HDDS-7197
URL: https://issues.apache.org/jira/browse/HDDS-7197
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Sammi Chen
Assignee: Sammi Chen
Currently RocksDB registers its statistics as jmx metrics with db file name,
which is same for all V3 and V2 containers. Then only the first register will
succeed, others will fail with following logs.
