Kubernetes has become the backbone of modern cloud-native applications.
Prometheus is an open-source monitoring and alerting toolkit designed for cloud-native environments. Grafana is an open-source visualization tool that works seamlessly with Prometheus.
The step-by-step guide to monitoring Kubernetes clusters with Prometheus and Grafana includes installing the tools using Helm, exposing the services, configuring Grafana to use Prometheus as a data source, and creating a Kubernetes monitoring dashboard.
Real-world applications of Prometheus and Grafana in DevOps include performance monitoring, alerting, capacity planning, and security monitoring.
