Description

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.reporters: prom 
metrics.reporter.prom.factory.class: org.apache.flink.metrics.prometheus.PrometheusReporterFactory 
metrics.reporter.prom.port: 9250-9251

 
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?
