Kafka Streams Monitoring and Metrics with Spring Boot
Explore how to integrate Kafka Streams with Spring Boot to monitor application performance. Learn to use Spring Boot Actuator and Micrometer to collect, expose, and customize metrics, gaining insights into stream processing health and bottlenecks.
Monitoring is an important aspect of every application in production. How does our app perform? Does it contain bottlenecks? Which classes and flows should be optimized? Without monitoring and metrics, it is hard to answer these questions.
Luckily, Spring Boot provides built-in and easy-to-use monitoring and metrics libraries. Micrometer is an open-source set of libraries used by Spring Boot to collect metrics, and Spring Boot Actuator is a Spring project that facilitates exposing the collected metrics using a REST API. Using these, we can collect and expose Kafka Streams’ metrics and define our own custom metrics.
