Monitoring with Prometheus & Grafana
Set up Prometheus for metrics collection and Grafana for visualization to monitor your cluster and application performance.
Why Monitor Kubernetes?
When running applications in Kubernetes, it's crucial to know how they're performing. Are your pods healthy? Is the cluster overloaded? Monitoring gives you these answers.
In this lesson, we'll explore two powerful tools: Prometheus for collecting metrics and Grafana for visualizing them.
Prometheus: The Metrics Brain
Prometheus is an open-source monitoring system that collects metrics from configured targets at given intervals, evaluates rule expressions, displays the results, and can trigger alerts.
- It uses a pull model: Prometheus scrapes (pulls) metrics from HTTP endpoints.
- It stores data as time-series data, meaning values are recorded over time.
