Hi Yury, Flink is using its own JMX server instance (not the JVM's one). Therefore, you can configure the server yourself. Check out this documentation page: https://ci.apache.org/projects/flink/flink-docs-release-1.2/monitoring/metrics.html#reporter
metrics.reporter.my_jmx_reporter.class: org.apache.flink.metrics.jmx.JMXReporter metrics.reporter.my_jmx_reporter.port: 9020-9040 Flink will print the port it is using in the end into the log of each TaskManager.
