[jira] [Commented] (CASSANDRA-15909) Make Table/Keyspace Metric
Names Consistent With Each Other
[ https://issues.apache.org/jira/browse/CASSANDRA-15909?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17148856#comment-17148856 ]
David Capwell commented on CASSANDRA-15909:
-------------------------------------------
As long as this is done without breaking the old names, then sounds good to me.

> As part of CASSANDRA-15821 it became apparent that certain metric names found in keyspace and tables had different names but were in fact the same metric - they are as follows:
> * Table.SyncTime == Keyspace.RepairSyncTime
> * Table.RepairedDataTrackingOverreadRows == Keyspace.RepairedOverreadRows
> * Table.RepairedDataTrackingOverreadTime == Keyspace.RepairedOverreadTime
> * Table.AllMemtablesHeapSize == Keyspace.AllMemtablesOnHeapDataSize
> * Table.AllMemtablesOffHeapSize == Keyspace.AllMemtablesOffHeapDataSize
> * Table.MemtableOnHeapSize == Keyspace.MemtableOnHeapDataSize
> * Table.MemtableOffHeapSize == Keyspace.MemtableOffHeapDataSize
> Also, client metrics are the only metrics to start with a lower case letter. Change those to upper case to match all the other metrics.
> Unifying this naming would help make metrics more consistent as part of CASSANDRA-15582
