The only workaround is to add some constant to this option before
deploying a Flink cluster.

Hi, Flink Dev
First of all, Happy New Year! I have a question about JM monitoring.
According to
https://ci.apache.org/projects/flink/flink-docs-stable/ops/metrics.html,
metrics.scope.jm only have <hostname> one variable, which seems to be not
enough for YARN deployment mode:
1. The metric doesn't contain identifiers like application id or job id.
2. Since multiple flink jobs can run in a single yarn cluster, it is
possible that multiple JM can run in a single host, but inside different
containers. Under current scope, metrics belonging to two flink jobs will
share identical metric name. e,g, <host>.jobmanager.
Status.JVM.Memory.Heap.Committed
Is there any walkaround or fix in roadmap? Thanks!
Best
Lu
