Prometheus Monitoring: From Basics to Kubernetes Deployment

Maintaining clear visibility into system health is critical for modern software reliability. This text-based course guides you through the foundational concepts of systems monitoring and metrics collection using Prometheus. You will progress from understanding core monitoring terminology to implementing production-ready alerting and deploying Prometheus within a Kubernetes cluster. Through detailed written explanations, step-by-step configuration guides, and practical code snippets, you will gain the confidence to instrument applications, write queries, and manage metrics at scale. What you'll learn: - Understand core monitoring concepts, TSDB architecture, and the four essential Prometheus metric types. - Query metrics effectively using PromQL to extract real-time system insights. - Instrument applications with client libraries to expose custom metrics for collection. - Configure Alertmanager to route notifications and manage system alerts. - Deploy and manage Prometheus on Kubernetes using modern operators and custom resource definitions. - Align your monitoring setup with modern observability standards, including OpenTelemetry compatibility. The course begins with essential monitoring definitions and architectural concepts before moving into hands-on configuration, query writing, and cluster-level deployment strategies. This course is designed for systems administrators, DevOps beginners, and developers looking to establish robust monitoring without needing prior experience with Prometheus.
