zhuhaifeng reassigned FLINK-4840: --------------------------------- Assignee: zhuhaifeng > Introduce an OperatorSystemMetricGroup > -------------------------------------- > > Key: FLINK-4840 > URL: https://issues.apache.org/jira/browse/FLINK-4840 > Project: Flink > Issue Type: Improvement > Components: Metrics > Reporter: zhuhaifeng > Assignee: zhuhaifeng > Priority: Minor > Fix For: 1.2.0 > > > There will introduces the OperatorSystemMetricGroup, which encapsulates the > insantiation of TPS meter, lantency/proc_time_cost histograms. > Operator related System metrics are not instantiated directly by the specific > Operator, but instead within the OperatorSystemMetricGroup contained in the > respective OperatorMetricGroup. They are then later accessed by relevant > components(maybe different places), instead of instantiated them identically > with static name constants. Other system scope metrics (maybe > delay/queue_in/queue_out) can add into the OperatorSystemMetricGroup some > later. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
