Observability

Purpose

Instrument a system so that a question you did not anticipate can still be answered from its telemetry. Monitoring tells you that something is wrong; observability lets you find out why without shipping new code.

When to Use

• Instrumenting a new service.
• An incident where the data needed to diagnose it did not exist.
• Defining SLOs and the alerts that derive from them.
• Reducing alert noise that the team has learned to ignore.
