Kafka Streams applications are outside of the scope of Kafka itself, they can be running anywhere. They generally work with many topics (in/out/internal/intermediates) and can be reset when you want to start it fresh again.
Conduktor can help you monitoring these applications, and the topics being used.
To do so, go to the Kafka Streams menu and click on
IMPORT TOPOLOGY, then:
application.id of your application
Specify the topology
Static: paste your topology directly inside Conduktor
by URL: paste the endpoint of your application exposing its topology.
Conduktor will automatically fetch it regularly, adapt the metrics accordingly, and warn you if it's down
Here is an example importing a Kafka Streams application using the application.id
myapplicationid and exposing a endpoint
Conduktor will then monitor the endpoint and display a summary (topics in and out) in the main listing:
If the application is down, the topology disappears and it becomes redish, time to call the developers!
Conduktor can help you in two ways:
Do it manually by specifying all of topics in/out/internals/intermediate. It's not super practical.
Do it with all topics already set because you imported the Topology within Conduktor already
A wizard will then helps you by explaining the steps:
If you're doing a reset of a registered Kafka Streams application within Conduktor, you can just hit Next until the end, everything is setup automatically! 🤩
