Implement and scale queries, dashboards, and alerting across machines and containers

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 around monitoring and explores Prometheus architecture, its data model, and how metric aggregation works. Multiple test environments are included to help explore different configuration scenarios, like 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.
