未显示Flink延迟指标 [英] Flink latency metrics not being shown

问题描述

在本地环境中运行Flink 1.5.0时，我试图通过REST(类似于http://localhost:8081/jobs/e779dbbed0bfb25cd02348a2317dc8f1/vertices/e70bbd798b564e0a50e10e343f1ac56b/metrics的东西)获取延迟指标，但是没有对latency的引用.

While running Flink 1.5.0 with a local environment I was trying to get latency metrics via REST (with something similar to http://localhost:8081/jobs/e779dbbed0bfb25cd02348a2317dc8f1/vertices/e70bbd798b564e0a50e10e343f1ac56b/metrics) but there isn't any reference to latency.

所有这些在启用延迟跟踪的同时，我通过与调试器确认LatencyMarksEmitter正在发出标记来确认.

All of this while the latency tracking is enabled which I confirmed by checking with the debugger that the LatencyMarksEmitter is emiting the marks.

我该怎么办?

推荐答案

在1.5中，延迟指标未针对任务公开，而是针对作业，原因是延迟指标固有地包含有关多个任务的信息.您必须查询" http://localhost:8081/jobs/e779dbbed0bfb25cd02348a2317dc8f1/metrics "

In 1.5 latency metrics aren't exposed for tasks but for jobs instead, the reasoning being that latency metrics inherently contain information about multiple tasks. You have to query "http://localhost:8081/jobs/e779dbbed0bfb25cd02348a2317dc8f1/metrics" instead.
