Hands-On Infrastructure Monitoring with Prometheus

Prometheus is an open-source monitoring system with a dimensional data model, flexible query language, efficient time series database and modern alerting approach. This book will be your practical guide to setup Prometheus on your cloud, virtual machine, container, and server ecosystem.

---

Build Prometheus ecosystems with metric-centric visualization, alerting, and querying

Key Features

Integrate Prometheus with Alertmanager and Grafana for building a complete monitoring system
Explore PromQL, Prometheus' functional query language, with easy-to-follow examples
Learn how to deploy Prometheus components using Kubernetes and traditional instances

Book DescriptionPrometheus is an open source monitoring system. It provides a modern time series database, a robust query language, several metric visualization possibilities, and a reliable alerting solution for traditional and cloud-native infrastructure.

This book covers the fundamental concepts of monitoring and explores Prometheus architecture, its data model, and how metric aggregation works. Multiple test environments are included to help explore different configuration scenarios, such as the use of various exporters and integrations. You’ll delve into PromQL, supported by several examples, and then apply that knowledge to alerting and recording rules, as well as how to test them. After that, alert routing with Alertmanager and creating visualizations with Grafana is thoroughly covered. In addition, this book covers several service discovery mechanisms and even provides an example of how to create your own. Finally, you’ll learn about Prometheus federation, cross-sharding aggregation, and also long-term storage with the help of Thanos.

By the end of this book, you’ll be able to implement and scale Prometheus as a full monitoring system on-premises, in cloud environments, in standalone instances, or using container orchestration with Kubernetes.
