[英]"No Metrics " in Flink webUI
I started a local flink server (./bin/start-cluster.sh), and submitted a job.我启动了一个本地 flink 服务器(./bin/start-cluster.sh),并提交了一个作业。 I have the following code to define a custom metric:
我有以下代码来定义自定义指标:
.map(new RichMapFunction<String, String>() {
private transient Counter counter;
@Override
public void open(Configuration config) {
this.counter = getRuntimeContext()
.getMetricGroup()
.counter("myCounter");
}
@Override
public String map(String value) throws Exception {
this.counter.inc();
return value;
}
})
But when I run the job and send some data, I cannot see any metrics in flink web UI, just "No metrics"但是当我运行作业并发送一些数据时,我在 flink Web UI 中看不到任何指标,只有“没有指标”
I had configured the JMX reporter in the flink-conf.yaml.我已经在 flink-conf.yaml 中配置了 JMX 报告器。 I am not sure how could I get the metrics shown on the dashboard?
我不确定如何获得仪表板上显示的指标?
I had the same problem.我有同样的问题。 My problem was in cluster configuration, I was using the hostname to name the taskmanager, and when I change it (using the default name) , the task metrics start to work.
我的问题出在集群配置中,我使用主机名来命名任务管理器,当我更改它时(使用默认名称),任务指标开始工作。 I use docker-swarm to deploy the flink cluster.
我使用 docker-swarm 来部署 flink 集群。
