Metrics and Health Checks
Utilize metrics and health checks to monitor the real-time performance and availability of your microservices and patterns.
Welcome to Monitoring
In distributed systems, knowing what's happening is vital. That's where metrics and health checks come in!
They help us understand how our services are performing and if they're even alive. This lesson will show you how to use them effectively.
Understanding Metrics
Metrics are numerical measurements collected over time. Think of them as vital signs for your applications.
- Counters: Count events (e.g., requests received).
- Gauges: Show a current value (e.g., current CPU usage).
- Histograms/Timers: Measure distributions and durations (e.g., request latency).
