---------------------------------------

If you are using Kafka source / sink you might not be doing something wrong. There is a bug in Flink 1.15.0. Please find more infos here:

> I have a Standalone cluster (with jobmanager and taskmanager on same machine) on 1.14.4 and I'm testing the migration to 1.15.0
> But I keep losing the taskmanager metrics when I start a job on the 1.15 cluster
> I use the same configuration as in the previous cluster

> metrics.reporter.prom.factory.class: org.apache.flink.metrics.prometheus.PrometheusReporterFactory 
> metrics.reporter.prom.port: 9250-9251{code}
> {{ }}
> If the cluster is running without jobs I can see the metrics on port 9250 for jobmanager and on port 9251 for taskmanager
> If I start a job, the metrics from taskmanager disappear and if I stop the job the metrics come live again
> What am I missing?
