Observability Engineering

Instrumenting systems so their internal state is interrogatable from the outside.

Overview

Read the full Observability Engineering guidance
Observability is the property of a system whose internal state can be inferred from its outputs — structured logs, metrics, and distributed traces with consistent identifiers. Monitoring tells you THAT something is wrong; observability lets you ask WHY without shipping new code to find out. High-cardinality, high-dimension events are the raw material; dashboards and alerts are downstream projections. OpsRoadmaps assesses observability through tracing coverage across service boundaries, structured logging with correlation IDs, SLO-backed alerting (page on symptoms, not causes), and debuggability latency — how long it takes an engineer to answer a novel question about production without adding instrumentation.

Capabilities

  • Alerting

    Symptom-based, SLO-backed alerts that page a human only when a user-visible promise is burning.

  • Distributed Tracing

    End-to-end request traces across service boundaries with consistent context.

  • Log Management

    Structured, centralized, retention-governed logs with correlation identifiers.

  • Monitoring Coverage

    Metrics and health signals across the full estate, including the parts nobody owns.

Metrics

  • Alert Noise Ratio

    Share of pages that required no action.

    Unit: %. Good direction: down.
