Question

我将Flink配置为向JMXReporter公开指标，正如它所说的here。我还配置了一个工作程序节点，使其也将其指标显示给主节点，就像它所说的here。以下是主节点和工作节点上conf/flink-conf.yaml文件的配置。 Flink日志文件说它已连接到JMX服务器。然后，我打开VisualVM并连接到我的JMX服务器，然后转到“ MBeans”选项卡。在那里，我看到了JobManager软件包。但是，我找不到我创建的计数器和仪表。我还安装了JConsole插件。但是，当我转到JConsole选项卡时，会看到以下消息：No JConsole plugin installed. To install a JConsole plugin click the Configure Plugins button and provide full path to the plugin file/directory。根据{{3}}，我需要一个WtJmxPlugin.jar文件，但我不知道在哪里找到。

我有一个RichMapFunction正在公开指标。

public static class SensorTypeMapper
        extends RichMapFunction<MqttSensor, Tuple2<CompositeKeySensorType, MqttSensor>> {
    private static final long serialVersionUID = -4080196110995184486L;

    private transient Counter counter;
    private transient Meter meter;

    @Override
    public void open(Configuration config) {
        this.counter = getRuntimeContext().getMetricGroup().counter("counterSensorTypeMapper");

        com.codahale.metrics.Meter dropwizardMeter = new com.codahale.metrics.Meter();
        this.meter = getRuntimeContext().getMetricGroup().meter("meterSensorTypeMapper",
                new DropwizardMeterWrapper(dropwizardMeter));
    }

    @Override
    public Tuple2<CompositeKeySensorType, MqttSensor> map(MqttSensor value) throws Exception {
        this.meter.markEvent();
        this.counter.inc();
        // every sensor key: sensorId, sensorType, platformId, platformType, stationId
        // Integer sensorId = value.getKey().f0;
        String sensorType = value.getKey().f1;
        Integer platformId = value.getKey().f2;
        // String platformType = value.getKey().f3;
        Integer stationId = value.getKey().f4;
        CompositeKeySensorType compositeKey = new CompositeKeySensorType(stationId, platformId, sensorType);
        return Tuple2.of(compositeKey, value);
    }
}

如何可视化来自VIsualVM上暴露给JMX服务器的Flink的仪表和计数器指标？
