Hands-On Infrastructure Monitoring with Prometheus

By: Joel Bastos, Pedro Araújo

Overview of this book

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. 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.

More exporters

The Prometheus community has produced a great number of exporters for just about anything you might need. However, making an intentional choice to deploy a new piece of software in your infrastructure has an indirect price to pay upfront. That price translates into the deployment automation code to be written, the packaging, the metrics to be collected and alerting to be created, the logging configuration, the security concerns, the upgrades, and other things we sometimes take for granted. When choosing an open source exporter, or any other open source project for that matter, there are a few indicators to keep in mind.

We should validate the community behind the project, the general health of contributions, if issues are being addressed, pull requests are being timely managed, and whether the maintainers are open to discuss and interact with the community. Technically...
