Ted Yu updated HBASE-4768: -------------------------- Status: Open (was: Patch Available) > Per-(table, columnFamily) metrics with configurable table name inclusion > ------------------------------------------------------------------------ > > Key: HBASE-4768 > URL: https://issues.apache.org/jira/browse/HBASE-4768 > Project: HBase > Issue Type: New Feature > Reporter: Mikhail Bautin > Assignee: Mikhail Bautin > Fix For: 0.94.0 > > Attachments: 4768.addendum, D363.1.patch, D363.2.patch, D363.3.patch, > D363.4.patch, D363.5.patch > > > 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. -- This message is automatically generated by JIRA.
