MiniFi Java Agent 0.5

Copy over necessary NARs from Apache NiFi 1.7 lib:

  • nifi-ssl-context-service-nar-1.7.0.nar
  • nifi-standard-services-api-nar-1.7.0.nar
  • nifi-kafka-1-0-nar-1.7.0.nar

This will support PublishKafka_1_0 and ConsumeKafka_1_0.

Then create a consume and/or publish flow. You can combine the two based on your needs. In my simple example I consume the Kafka messages in MiniFi and write to a file. I also write the metadata to a JSON file.

Consume Kafka

Publish Electric Monitoring Data To Kafka

Let's monitor the messages going through our topic, smartPlug.
