zhuhaifeng created FLINK-4840: --------------------------------- Summary: Introduce an OperatorSystemMetricGroup Key: FLINK-4840 URL: https://issues.apache.org/jira/browse/FLINK-4840 Project: Flink Issue Type: Improvement Components: Metrics Reporter: 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)
