Chesnay Schepler commented on FLINK-5552:
-----------------------------------------

[~rongr] The port is available through the logs already, along the lines of 
"Started JMX server on port 1234."

> Make the JMX port available through RESTful API

> Currently, JMXReporter will create a server for JMX viewer retrieving JMX 
> stat. The port can be configured through configuration options, but for large 
> cluster with many machines running many Flink instances and other processes, 
> we cant set a fixed port to JMX server, making it difficult to get the JMX 
> port.
> This JIRA is to suggest adding an api at web frontend so that it is very easy 
> to get the JMX port for JM and TM.
