Hello, I'm trying to connect Prometheus to Flink metrics endpoint, but Prometheus can`t connect to port, seems like port is not opening:

destinations-processor-jobmanager    ClusterIP   10.100.199.42    <none>        6123/TCP,6124/TCP,8788/TCP,9250/TCP   20h

I`m using flink version 1.17 and flink kubernetes operator version 1.5.0. Metrics reporter has enabled and flink kubernetes operator has param metrics.port = 9250

metrics.reporter.prom.class: "org.apache.flink.metrics.prometheus.PrometheusReporter"
    metrics.reporter.prom.port: "9250"
    kubernetes.operator.metrics.reporter.prom.factory.class: "org.apache.flink.metrics.prometheus.PrometheusReporterFactory"
    kubernetes.operator.metrics.reporter.prom.port: "9250"

As you can see i`m trying both solutions, connection to service and to kubernetes operator, but no one is working.

Get "<http://11.0.31.192:9250/metrics>": dial tcp 11.0.31.192:9250: connect: connection refused

Can you please give a suggestion, what can be wrong?

Facing same issue here. Seems like Flink just don't open any port here?

adding a reporter factory helped

metrics.reporter.prom.factory.class: "org.apache.flink.metrics.prometheus.PrometheusReporterFactory"
