What is the format for additional_consumer_properties = <value>? I want to add a "node node" I'm not sure but maybe this is called a brokerid. Anyway how to do we add it to the inputs.conf "additional_consumer_properties = brokerid:myid"?
key=value,key2=value2,key3=value3 ....
Where key is a property in this list : http://kafka.apache.org/documentation.html#consumerconfigs
This is also detailed on the UI :
