Kafka Connect - metrics through JMX

Question

I am using confluent HDFS sink connector and would like to know how to get consumer properties to expose through either JMX or REST API.

I checked the following two properties, however, I don't know how to expose metrics to jmx port

connect-standalone.properties
consumer.properties

If you want to use REST, then use Jolokia and see https://stackoverflow.com/a/45984363/2308683 — OneCricketeer, Mar 08 '19 at 16:58

Set JMX_PORT when you launch Kafka Connect. e.g.

export JMX_PORT=4242
./bin/connect-distributed ./etc/kafka/connect-distributed.properties

You can then connect to JMX using JConsole, JMXTerm, etc.

I modified the file `./bin/connect-distributed` and mentioned the port inside it `JMX_PORT=4242` and then restarted the service. However it's not working – Gaurang Shah Mar 11 '19 at 15:06

Had the same issue a few days back - this stackoverflow link has one way how the issue was resolved. It was able to expose the metrics using jmx exporter, which got scraped by Prometheus.
