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.

Managing Prometheus in Kubernetes

Kubernetes is the first project to graduate from the CNCF and is currently the de facto standard for container orchestration. Early on, Heapster was widely used as a monitoring solution that came out-of-the-box with Kubernetes. It started out as a tool to send monitoring data to external systems but then grew to become a monitoring system itself. However, it didn't take long for Prometheus to become the de facto standard monitoring system for Kubernetes clusters. Nowadays, most of the components that make up a Kubernetes cluster have native Prometheus instrumentation.

In the following sections, we'll go into how to integrate Prometheus in a Kubernetes environment by employing examples based on the Kubernetes project and the Prometheus Operator project.

You can find the complete source code of the Kubernetes project and the Prometheus...
