Title: Hands-On Infrastructure Monitoring with Prometheus
Description: Prometheus 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. It delves into PromQL, supported by several examples, and then applies 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 one from scratch. Finally, it teaches Prometheus federation, cross-sharding aggregation, and also long-term storage with the help of Thanos.
