bacnet2mqtt looks simple in a README and expensive in production. Once BACnet polling, reconnection behavior, stale state, and MQTT publishing collide, teams discover they are not deploying a lightweight adapter but operating infrastructure. This article breaks down where bacnet2mqtt works, where it becomes a bottleneck, and which production patterns reduce the operational damage before incidents, backlogs, and silent data loss turn a building integration into a long-running engineering problem. I inherited a building controls integration problem 18 months ago. Three office floors. 217 BACnet sensors covering temperature, occupancy, and HVAC actuators. The data was trapped inside the building automation network while the business wanted analytics, reporting, and compliance visibility in the data platform. The obvious answer looked easy enough: deploy bacnet2mqtt, bridge BACnet into MQTT, and push the stream into the lakehouse stack. The repository made it sound like a w...

Agent observability breaks down when teams try to force long-lived, stateful workflows into dashboards built for stateless microservices. In production, the real challenge is not collecting more logs. It is reconstructing what the agent saw, what state changed, which tool response altered the workflow, and why the system kept going. This article explains why replayable event streams are a better foundation for multi-agent tracing, how a Kafka-first design makes session replay practical, and where conventional tracing still helps but falls short on its own. The production failure that changed how we instrument agents I still remember the first time one of our production agent systems failed without actually crashing. An invoice-processing agent entered a recursive reasoning loop and burned through hundreds of dollars in API credits over a weekend because it kept insisting a validation error existed when it did not. We had logs. We had metrics. We had distributed traces. None of...
