Logs vs. Metrics: Why You Need Both for Observability
Picture this: Your dashboards are calm. CPU load is steady. Error rates are low. Everything looks fine. That is, until the alarms go off. Now what? Metrics tell you something’s wrong, but not what, where, or why. They reveal symptoms, not root causes, and in high-stakes environments, that’s only half the story. Say your API response times spike. Metrics raise the flag, but they don’t tell you if it’s a code deployment, a database hang, or a traffic surge.
