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.

Common Alertmanager notification integrations

Users and/or organizations have different requirements regarding notification methods; some might be using HipChat as a means of communication, while others rely on email, on-call usually demands a pager system such as PagerDuty or VictorOps, and so on. Thankfully, Alertmanager provides several integration options out of the box and covers most of the notification needs you might have. If not, there's always the Webhook notifier, which allows integration with custom notification methods. Next, we'll be exploring the most common integrations and how to configure them, as well as providing basic examples to get you started.

Something to keep in mind when considering integrating with chat systems is that they're designed for humans, and the use of a ticketing system is advised when thinking about low-priority alerting....
