Monitoring Kafka in production is critical for ensuring data pipeline reliability. This guide walks through setting up Prometheus to capture essential Kafka metrics, including broker throughput, request rates, and consumer group lag. It explains how to configure exporters, define alerting rules, and build dashboards for real-time observability. The approach is vendor-neutral and works with both on-premises and cloud deployments. For teams already using Prometheus, this provides a structured way to extend monitoring to Kafka without additional commercial tools. The focus on consumer lag is particularly valuable for detecting processing bottlenecks early.
