Visualization​

  • For the sake of the demo test events are constantly generated to corresponding AKHQ Kafka topics
    • You can see a listed topic, its counts and size, you can even explore what's inside the topic by 'double click' on its name.
    • You can see topics schema in the 'Schema Registry' tab. Based on that schema Nussknacker Designer provides code completion and validation of Kafka events.
    • You can click the 'counts' button to see live data statistics.
  • You can see how a scenario is working in its Grafana metrics panel. Here are various plots representing e.g.:
    • service throughput - how many events per second pass-through scenario.
    • rejected events - how many events have not fulfilled scenario conditions.
    • External services - e.g. enrichers - details on external HTTP requests performance.
    • General scenario stats - uptime, checkpoint duration, number of restarts.
