Building Production-Grade System Observability in Go
· 6 min read
When we set out to build HyperSDK's observability layer, we had a clear constraint: no external dependencies. No Prometheus node exporter, no collectd, no StatsD sidecar. The daemon had to collect, store, analyze, and serve system metrics entirely on its own. This is the story of how we built a self-contained observability stack in Go using nothing but /proc, /sys, and a ring buffer.
