Hi Flink-Users, After upgrading to Flink 1.15 (rc3) (coming from 1.14) I noticed that there is a problem with the metrics exposed through the PrometheusReporter.
It is configured as followed in the flink-config.yml: metrics.reporters: prom metrics.reporter.prom.class: org.apache.flink.metrics.prometheus.PrometheusReporter metrics.reporter.prom.port: 4444 My cluster is running in standalone mode with 2 taskmanagers and 2 jobmanagers. More specifically: On the taskmanger that runs a job I get curl: (52) Empty reply from server when I call curl localhost:4444. I was looking for the metrics in the namespace flink_taskmanager_job_*, which are only - and obviously - exposed on the taskmanager running a job. On the other taskmanger that runs no job I get a response with a couple of metrics of the namespace flink_taskmanager_Status - as expected. When configuring the JMXReporterFactory for too. I find the desired and all other metrics via VisualVM on that taskmanager running the job. Also in the Flink web ui, in the "Jobs -> Overview -> Metrics" part I can select and visualize metrics like flink_taskmanager_job_task_busyTimeMsPerSecond. Does someone have any idea what's going on here? maybe even confirm my findings? Best & thanks, Peter
