We need guardrails to help protect us from shipping code that will result in unexpected regressions. We need breadcrumbs that we can follow back to the source to help us identify why a metric may have changed. Automated testing of code changes Another important guardrail is to have automated performance testing when code changes occur.

But, manual steps — such as reviewing test results and addressing production issues resulting from performance, resiliency, security, or functional issues — often hinder these efforts. Observability is the ability to measure a system’s current state based on the data it generates, such as logs, metrics, and traces.
