The Four Signals
A monitoring stack built around latency, traffic, errors, and saturation.
The work
The challenge
Make production symptoms visible and connect an alert to something an operator can actually do.
The approach
Organize telemetry around the four golden signals, then connect metrics, logs, and actionable runbooks.
Implementation
The linked Linux monitoring stack provides the technical context. The journal explores the monitoring and logging approach in depth.
Context & results
Architecture and tooling are the evidence here. Latency and nine-service claims from the old homepage are not presented as independently verified results.
