Service Monitoring

Documentation on how services are monitored.

What is Service Monitoring?

Service monitoring involves collecting metrics (numerical data) from your applications to understand their performance and health. In Kubernetes, this is often done using the Prometheus Operator, which defines a ServiceMonitor resource. A ServiceMonitor tells Prometheus custom resources which internal Kubernetes Services to scrape for metrics.
