Paul Yang commented on HIVE-1818: --------------------------------- Taking a look.. > Call frequency and duration metrics for HiveMetaStore via jmx > ------------------------------------------------------------- > > Key: HIVE-1818 > URL: https://issues.apache.org/jira/browse/HIVE-1818 > Project: Hive > Issue Type: New Feature > Components: Metastore > Reporter: Sushanth Sowmyan > Assignee: Sushanth Sowmyan > Priority: Minor > Fix For: 0.7.0 > > Attachments: HIVE-1818-vs-1054860.patch, HIVE-1818-vs-1063088.patch, > HIVE-1818.patch > > > As recently brought up in the hive-dev mailing list, it'd be useful if the > HiveMetaStore had some sort of instrumentation capability so as to measure > frequency of calls to various calls on the HiveMetaStore and the duration of > time spent in these calls. > There are already incrementCounter() and logStartFunction() / > logStartTableFunction() ,etc calls in HiveMetaStore, and they could be > refactored/repurposed to make calls that expose JMX MBeans as well. Or, a > Metrics subsystem could be introduced which made calls to > incrementCounter()/etc as a refactor. > It might also be possible to specify a -D parameter that the Metrics > subsystem could use to determine whether or not to be enabled, and if so, on > to what port. And once we have the capability to instrument and expose > MBeans, it might also be possible for other subsystems to also adopt and use > this system. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
