Hands-On Infrastructure Monitoring with Prometheus

2 (1)
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.

Scaling and Federating Prometheus

Prometheus was designed to be run as a single server. This approach will allow you to handle thousands of targets and millions of time series but, as you scale, you might find yourself in a situation where this just is not enough. This chapter tackles this necessity and clarifies how to scale Prometheus through sharding. However, sharding makes having a global view of the infrastructure harder. To address this, we will also go through the advantages and disadvantages of sharding, how federation comes into the picture, and, lastly, introduce Thanos, a component that was created by the Prometheus community to address some of the issues presented.

In brief, the following topics will be covered in this chapter:

  • Test environment for this chapter
  • Scaling with the help of sharding
  • Having a global view using federation
  • Using Thanos to mitigate Prometheus...
