I have NiFi set up to publish logs into Kafka topics. The publishing of the logs to Kafka topics is working fine, but when I create a sensor in Metron Management UI, it is not receiving any of the data that is being published into the kafka topics.

I can see the logs as well when I use the kafka-console-consumer.sh script.
When I create the metron sensor, it automatically creates a storm parser and I can see it in the Storm UI page. But I do not see any of the logs in Metron or Storm. Is this a kafkaSpout issue? Possible settings within Metron that need to be changed? What do I need to do here?

(as you can see, there are 3 running sensors, but no throughput for the 3 kafka topics)
Can somebody point me in the direction to a solution for this please?
