Observability
Observability is the ability to understand what is happening inside a software system from its external outputs, chiefly metrics, logs and traces, so teams can detect, diagnose and resolve problems in complex distributed systems.
Observability is the ability to understand the internal state of a system from the data it produces, so that engineers can answer new questions about its behaviour without deploying new code. In software operations it rests on three main telemetry types: metrics, which are numeric measurements over time; logs, which are timestamped records of events; and traces, which follow a single request across services. Profiles are increasingly treated as an additional signal.
Observability extends traditional monitoring, which checks known failure conditions, to the unexpected failure modes of distributed systems such as microservices, serverless functions and Kubernetes clusters. It shortens the time to detect and diagnose incidents and supports service level objectives, capacity planning and performance tuning. Common tools include Prometheus, Grafana, the Elastic Stack and Jaeger, with OpenTelemetry providing vendor-neutral instrumentation.
Distributed tracing is a key technique: each request carries a trace context that links timed spans from every service it passes through, revealing where latency or errors arise. Telemetry volume and cost grow quickly, so sampling, retention policies and careful use of high-cardinality labels matter. Logs must not contain secrets or unnecessary personal data, and telemetry stores need access control like any other data store.
Key points
- Built on telemetry: metrics, logs and distributed traces, increasingly with profiles
- Goes beyond monitoring known failures to investigating unexpected behaviour
- Distributed tracing links spans across services to show where latency arises
- Sampling and retention policies keep telemetry cost under control
