Junegunn Choi created HBASE-28985: ------------------------------------- Summary: Fix memStoreSize metric for a table and add heap and off-heap size metrics Key: HBASE-28985 URL: https://issues.apache.org/jira/browse/HBASE-28985 Project: HBase Issue Type: Bug Components: metrics Reporter: Junegunn Choi
The "memStoreSize" metric for a table is incorrect as it reports the sum of the data size, the heap size, and the off-heap size, while "memStoreSize" metric for a region or a region server is just the data size. https://github.com/apache/hbase/blob/e082405d8e7fa5c9b89e7af3153f022731168ecb/hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/MetricsTableWrapperAggregateImpl.java#L79-L80 We should fix it to report only the data size for consistency and add additional metrics, similarly to HBASE-27892, not to lose the extra information for understanding the flush behavior. * {{memStoreHeapSize}} * {{memStoreOffHeapSize}} -- This message was sent by Atlassian Jira (v8.20.10#820010)
