Port selection not working

[senthil13]

Even though specfy different port than 9000, still the kafdrop listen on 9000.

ps ax | grep -i "kafdrop.jar" | egrep -v "grep" | awk '{print $1}'
1199

netstat -plant | grep 9000
tcp6       0      0 :::9000                 :::*                    LISTEN      1199/java

netstat -plant | grep 9010
tcp6       0      0 :::9010                 :::*                    LISTEN      1199/java

@senthil13
which command did you used to start kafdrop?
like java -jar kafdrop-3.8.1.jar --server.port=9001 > kafdrop.log &

nohup java -jar kafdrop.jar --zookeeper.connect=<servername:port> --server.port=9010 >> kafdrop.$(date +"%F").out &

@senthil13
i also tried on my local, it seems that port not be changed...

could you try the following one? i think it works.
nohup java -Dspring.application.json='{"server.port":9010}' -jar kafdrop.jar --zookeeper.connect=servername:port >> kafdrop.$(date +"%F").out &

Kafdrop uses Undertow to serve both the user-facing content (web pages and REST APIs) as well as the /actuator endpoint for serving metrics. These can be served on two different ports, but both default to 9000.

To change both, thereby freeing 9000 altogether, pass in the following arguments:

--server.port=9001 --management.server.port=9001

Updated the README for the 'make-benefit of future generation' :) And closing issue.

Environment variables SERVER_PORT and MANAGEMENT_SERVER_PORT also work, although the README only mentions the former.
