Code Instrumentation: Making Your App Observable
Instrumentation is like adding a flight recorder to your app, emitting telemetry about its internal state. It's how you generate traces, metrics, and logs for observability tools. The main footgun is over-instrumenting, creating noisy and expensive data.
Instrumentation is like adding sensors to your code to emit telemetry—traces, metrics, and logs—that act as a flight recorder for your software. It's used to trace requests, monitor health with metrics, and debug with logs, via automatic agents or manual SDKs. The footgun is relying only on auto-instrumentation; it often misses critical business context that manual instrumentation provides, leaving you blind during an incident.
