R. Tyler Croy a444f49b46 Invoke the onDelta callbacks for zero deltas too 
It turns out that datadog doesn't indicate that the delta is shrinking unless
you report a zero value.

Verspätung

BuildStatus

Verspätung is a small utility which aims to help identify delay of Kafka consumers.

Verspätung monitors the topics and their latest offsets by talking to Kafka, it will also keep track of how far along consumers are by monitoring the offsets that they have committed to Zookeeper. Using both of these pieces of information, Verspätung computs the delta for each of the consumer groups and reports it to statsd.

Hacking

  • Running tests: ./gradlew check
  • Running the app locally: ./gradlew run -PzookeeperHosts=localhost:2181
  • Building the app for distribution: ./gradlew shadowJar
