[jira] [Updated] (HBASE-4768) Per-(table, columnFamily) metrics
with configurable table name inclusion
[ https://issues.apache.org/jira/browse/HBASE-4768?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Phabricator updated HBASE-4768:
-------------------------------
Attachment: D363.1.patch
mbautin requested code review of "[jira] [HBASE-4768] Per-(table, columnFamily) metrics with configurable table name inclusion".
Reviewers: jgray, nspiegelberg, stack, tedyu, todd, JIRA
This is an initial version of an HBase trunk diff for per-table/CF metrics (see JIRA for details). Unit tests mostly pass -- need to look into TestDistributedLogSplitting. Also still doing cluster testing.
TEST PLAN
Unit tests, single-node cluster, dev cluster. Need to try bulk-load map-reduce jobs as well. Observe metrics through JMX.

> As we kept adding more granular block read and block cache usage statistics, a combinatorial explosion of various cases to monitor started to happen, especially when we wanted both per-table/column family/block type statistics and aggregate statistics on various subsets of these dimensions. Here, we un-clutters HFile readers, LruBlockCache, StoreFile, etc. by creating a centralized class that knows how to update all kinds of per-table/CF/block type counters.
> Table name and column family configuration have been pushed to a base class, SchemaConfigured. This is convenient as many of existing classes that have these properties (HFile readers/writers, HFile blocks, etc.) did not have a base class. Whether to collect per-(table, columnFamily) or per-columnFamily only metrics can be configured with the hbase.metrics.showTableName configuration key. We don't expect this configuration to change at runtime, so we cache the setting statically and log a warning when an attempt is made to flip it once already set. This way we don't have to pass configuration to a lot more places, e.g. everywhere an HFile reader is instantiated.
> Thanks to Liyin for his initial version of per-table metrics patch and a lot of valuable feedback.
