Hi All, Sorry to bother you all. It was simple. π Just put one line in required .sh file export JMX_PORT=<port number of your choice other than 9099>
and it will run π thanks, Sunil.

There is not problem till now. I can see metrics on kafka-manager console. This is fine. However when I run kafka-consumer-perf-test.sh and kafka-producer-perf-test.sh and similar utility under /bin then I get error given at the end: I understand the root cause. But I donβt know solution. Cant I make use of those test utilities given under /bin, when I enabled JMX? I want to measure performance of running kafka cluster and at the same time want to monitor metrics on kafka-manager. How can I skip JMX_port while running manual utilities? Or is there a way I can give different port for kafka-producer-perf-test.sh ? Please help me in this regards.
