Kafka Consumer

The Kafka consumer plugin polls a specified Kafka topic and adds messages to InfluxDB. The plugin assumes messages follow the line protocol. Consumer Group is used to talk to the Kafka cluster so multiple instances of telegraf can read from the same topic in parallel.

Testing

Running integration tests requires running Zookeeper & Kafka. The following commands assume you're on OS X & using boot2docker or docker-machine through Docker Toolbox.

To start Kafka & Zookeeper:

docker run -d -p 2181:2181 -p 9092:9092 --env ADVERTISED_HOST=`boot2docker ip || docker-machine ip <your_machine_name>` --env ADVERTISED_PORT=9092 spotify/kafka

To run tests:

go test
