Technical insights from cloud infrastructure, DevOps pipelines, and homelab engineering.
Synthetic monitoring is usually treated as uptime checking. I see it as the first signal in a reliability workflow: scripted probes detect failures, HARP turns them into evidence packs, OpenRAG enriches the diagnosis, and Nero-Camp routes the decision through human approval.
Three AI agents reviewed the draft of this post before it was published. They agreed on most things and disagreed on three. That disagreement is not a bug. It is exactly why I do not trust a single LLM to ship anything that matters.
What looked like a hardware noise problem was actually caused by workload behavior.
Using iotop, sensors, Docker inspection, and CPU affinity
tuning, I made my homelab dramatically quieter and cooler — with software-only changes.
