Hi community, I have built my own operator (not a UDF) and I want to collect the metrics of "outPoolUsage" inside it. How do I do it assuming that I have to do some modifications in the source code?
I know that the Gouge comes from flink-runtime/org.apache.flink.runtime.io.network.metrics.OutputBufferPoolUsageGauge.java. Inside of my operator MyAbstractUdfStreamOperator I can get the "MetricGroup metricGroup = this.getMetricGroup()". Then I implemented the "Gauge<Float> gauge = (Gauge<Float>) metricGroup.getMetric("outPoolUsage");" but it returns null all the time. Even when I click on the Backpressure UI Interface.
