Hello Chesnay, Thanks for your response ! I have logs enable (info), slf4jReporter is working, I can see :
15:16:00.112 [Flink-MetricRegistry-thread-1] INFO org.apache.flink.metrics.slf4j.Slf4jReporter - =========================== Starting metrics report =========================== -- Counters ------------------------------------------------------------------- -- Gauges --------------------------------------------------------------------- .... On both jobmanager & taskmanager, *BUT* i see only system metrics, not my custom one.. Am i missing something in declaration in my topology ? *Note* : I am using DataSet API (so my program is batch, and not continuous) Regards, Bastien ------------------ Bastien DINE Data Architect / Software Engineer / Sysadmin bastiendine.io Le mar. 27 nov. 2018 à 17:07, Chesnay Schepler <ches...@apache.org> a écrit : > Please enable WARN logging and check for warnings by the SLF4JReporter > and/or MetricQueryService. > > On 27.11.2018 17:00, bastien dine wrote: > > 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 String metricGroup; > private final String metricName; > > > 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 > > ------------------ > > > Bastien DINE > Data Architect / Software Engineer / Sysadmin > bastiendine.io > > >
