ActiveMQ Log Analysis & Diagnostics: The Expert Guide
Senior engineers who are fast at diagnosing ActiveMQ incidents share one trait: they know exactly what they are looking for in the broker log before they open it. They know the PFC signature, the OOM warning pattern, the journal recovery sequence, and the connection drop format. For them, the log is not text to search through, it is a structured operational record that maps each entry to a specific broker state.

ActiveMQ Capacity Planning: The Complete Framework
Most ActiveMQ deployments are sized in one of two ways: either under-provisioned from underestimating growth ("we'll upgrade when we need to") or over-provisioned from anxiety ("better give it 32GB just in case"). Both approaches are avoidable with a structured capacity planning framework that translates your messaging workload characteristics into specific hardware and configuration requirements.

ActiveMQ Backup and Disaster Recovery: Complete DR Guide
A message broker's backup and disaster recovery plan is the last line of defense against scenarios that HA cannot address: a full datacenter outage, catastrophic hardware failure that destroys both primary and secondary nodes, accidental message deletion, or KahaDB corruption that prevents the broker from starting.

ActiveMQ JVM Memory & GC Tuning: Heap Sizing, G1GC, ZGC Guide
The JVM is the runtime foundation of every ActiveMQ deployment. Message throughput, delivery latency, producer flow control triggers, OOM crashes, and GC-induced delivery pauses all trace back to JVM memory configuration. Yet ActiveMQ ships with a 512MB heap and no GC logging, appropriate for a developer laptop, not for an enterprise message broker handling millions of messages a day.

ActiveMQ Network of Brokers: The Complete Configuration Guide
Distributed enterprise applications eventually need to exchange messages across network boundaries - between datacenters, between application tiers, between geographic regions. A single broker cannot serve all of them efficiently.

Apache ActiveMQ® vs Apache Artemis™: The 2026 Definitive Guide
When engineers search for "Apache ActiveMQ vs Apache Artemis," most of what they find is either a shallow feature checklist or a confident recommendation to "just migrate to Apache Artemis." Neither helps a senior architect deciding whether to stay on a stable, battle-hardened Apache ActiveMQ deployment, or a platform team evaluating both options for a new system with clear eyes.
