You build your streaming applications and event-driven microservices using Apache Kafka. Are your systems observable enough without depending only on the broker-side metrics and application logs? Can you track down the root cause during incidents, or do you hope everything will be fine after a restart? In this talk, Tim & Kosta will take you on their observability journey by sharing pitfalls and knowledge our team gained over the last couple of years. We are going to answer questions like: * Do you understand how to expose and use your client-side Kafka metrics? * JMX, Metric interceptors, Micrometer where to start? * Why is there a difference between the values of client-side and broker-side metrics? * Learn how client-side consumer lag metrics can differ from the lag calculated on the cluster. * What is the right way to use and interpret them? * Can you measure latency through your complete stack using distributed tracing? * OpenTelemetry, Jaeger & Zipkin, what to pick? During a step-by-step demo, we will look into different real-life examples and scenarios to demonstrate how to bring the observability of your Kafka applications to the next level. Kickstart your observability journey today and join this talk!
