Hello everyone,
Once again I require your help !
I am trying to report custom metric (see my code below)
Yet, I do not see them anywhere.. nor in the metric tab from my tasks,
nor in the rest API, nor in the declared slf4j reporter..
Can someone help me to debug this ..
Here is my RichMap function :
public class MetricGaugeRichMap<T,E extends MetricTuple<T>> extends
RichMapFunction<E,E> {
private transient T valueToExpose;
private final StringmetricGroup;
private final StringmetricName;
public MetricGaugeRichMap(String metricGroup, String metricName) {
this.metricGroup = metricGroup;
this.metricName = metricName;
}
@Override public void open(Configuration config) {
getRuntimeContext()
.getMetricGroup()
.addGroup(metricGroup)
.gauge(metricName, (Gauge<T>) () -> valueToExpose);
}
@Override public E map(E metricTuple)throws Exception {
valueToExpose = metricTuple.getMetricValue();
return metricTuple;
}
}
calling from topology :
env.fromElements(new MetricTuple<>(metricGroup,metricName,metricValue))
.map(new MetricGaugeRichMap<>(metricGroup,metricName))
.output(new MetricGaugeOutputFormat<>()); // dummy output
