-------------------------------
Resolution: Invalid
> Custom metrics not being exposed for Prometheus
> -----------------------------------------------
>
> Key: FLINK-8284
> URL: https://issues.apache.org/jira/browse/FLINK-8284
> Project: Flink
> Issue Type: Bug
> Components: Documentation, Metrics
> Affects Versions: 1.4.0
> Environment: Linux/CentOS 7
> Reporter: Julio Biason
>
> Following the documentation, we changed our filter that removes events with missing fields to a RichFilterFunction, so we can capture metrics about such events:
> {code:scala}
> public class MissingClientFilter extends RichFilterFunction<LineData> {
> private transient Counter counter;
> @Override
> public void open(Configuration config) {
> this.counter = getRuntimeContext()
> .getMetricGroup()
> .addGroup("events")
> .counter("missingClient");
> }
> @Override
> public boolean filter(LineData line) {
> String client = line.get("client").toString();
> boolean missing = client.trim().equals("");
> if (!missing) {
> this.count();
> }
> return !missing;
> }
> private void count() {
> if (this.counter != null) {
> this.counter.inc();
> }
> }
> }
> {code}
> We also added Prometheus as our reporter:
> {noformat}
> metrics.reporters: prom
> metrics.reporter.prom.port: 9105
> metrics.reporter.prom.class: org.apache.flink.metrics.prometheus.PrometheusReporter
> {noformat}
> The problem is accessing port 9105 display all Flink metrics, but not ours.
