-# What is Error Monitoring?
-
 Error monitoring is your app's always-on debugger. It tracks crashes, exceptions, and runtime issues as they happen—complete with stack traces, request data, environment details, and user context.

Think of error monitoring as a babysitter for your code, but one that actually tells you *why* the baby's crying.
