Flink backpressure ratio
WebFlink exposes a metric system that allows gathering and exposing metrics to external systems. Registering metrics You can access the metric system from any user function that extends RichFunction by calling getRuntimeContext ().getMetricGroup () . This method returns a MetricGroup object on which you can create and register new metrics.
