---------------------------------------
[~eskabetxe] oke! In the mailing list thread Cheasney also gave a way to
forward j.u.l. loggings to slf4j, so you could maybe investigate further.

> Issue Type: Bug
> Components: Runtime / Metrics
> Affects Versions: 1.15.0
> Reporter: João Boto
> Priority: Major
>
> 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
> {{ }}
> {code:java}
> metrics.reporters: prom
> 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?
