[jira] [Updated] (HDDS-4839) RocksDB statistics not exposed on
Ozone DN
[ https://issues.apache.org/jira/browse/HDDS-4839?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Aravindan Vijayan updated HDDS-4839:
------------------------------------
Description:
Setting ozone.metastore.rocksdb.statistics = ALL, I can find the rocksdb stats exposed in OM JMX
{noformat}
"name" : "Hadoop:service=Ozone,name=RocksDbStore,dbName=om.db",
{noformat}
but the entry is not found on DN if I try to enable this property on a DN. Initial hunch is that the tocksdb stats is created per DN, and DN has many DBs. When one DB is closed, the corresponding JMX entry is removed.
This bug is similar to HDDS-4722.
