observability-and-instrumentation

Code instrumentation for production observability is the process of adding structured logging, metrics, tracing, and alerting to diagnose issues in running features.

You add structured logging and distributed tracing by instrumenting production code with telemetry data, ensuring features generate diagnostic logs and trace spans for issue resolution.

The best way to set up RED metrics and alerting is to instrument the feature with actionable symptoms, configuring rate, error, and duration metrics to trigger alerts during production issues.

Yes, this observability approach applies to any feature running in production that requires diagnostic data, applying structured logging, RED metrics, and distributed tracing without specific dependencies.

You need distributed tracing and telemetry data for production monitoring to maintain visibility into running code, enabling accurate diagnosis and resolution of issues that arise after deployment.

Relying on basic logging limits production diagnosis because it lacks the RED metrics and distributed tracing necessary to pinpoint actionable symptoms across complex deployed features.
