Hang Ruan commented on FLINK-29801: ----------------------------------- Hi, [~stevenz3wu] , For question 1, we want to provide some common metrics in the `OperatorCoordinatorMetricGroup` like other metric groups, such as `SinkWriterMetricGroup`. So we provide the `numEventsIn` for it. For question 2, when invoking `SourceCoordinatorProvider#getCoordinator(OperatorCoordinator.Context context)`, we could get the `OperatorCoordinatorMetricGroup` by the method `metricGroup()` in `OperatorCoordinator.Context`. The discussion will be sent this week or later. Thanks for the reply. > OperatorCoordinator need open the way to operate metricGroup interface > ---------------------------------------------------------------------- > > Key: FLINK-29801 > URL: https://issues.apache.org/jira/browse/FLINK-29801 > Project: Flink > Issue Type: Improvement > Components: Runtime / Metrics > Reporter: yuemeng > Assignee: yuemeng > Priority: Major > Labels: pull-request-available > > Currently, We have no way to get metric group instances in OperatorCoordinator > In some cases, we may report some metric in OperatorCoordinator such as Flink > hudi integrate scene, some meta will send to operator coordinator to commit > to hdfs or hms > but we also need to report some metrics in operator coordinator for monitor > purpose -- This message was sent by Atlassian Jira (v8.20.10#820010)
