Most messaging incidents don’t begin with outages. They begin with a subtle imbalance. Queue depth grows gradually, consumers fall slightly behind, retries increase, and latency quietly accumulates across distributed systems. By the time performance degradation becomes visible, the original cause is often difficult to trace.
Built for platform engineers, architects, and middleware teams operating Apache ActiveMQ® and Apache Artemis™ at scale, this handbook explores how messaging systems drift under real production conditions, the operational patterns behind the most common incidents, and why modern messaging environments require more than traditional monitoring to remain stable, observable, and under control.
