Book Description
By finelybook
Get up to speed with Prometheus, the metrics-based monitoring system used in production by tens of thousands of organizations. This updated second edition provides site reliability engineers, Kubernetes administrators, and software developers with a hands-on introduction to the most important aspects of Prometheus, including dashboarding and alerting, direct code instrumentation, and metric collection from third-party systems with exporters.
Prometheus server maintainer Julien Pivotto and core developer Brian Brazil demonstrate how you can use Prometheus for application and infrastructure monitoring. This book guides you through Prometheus setup, the Node Exporter, and the Alertmanager, and then shows you how to use these tools for application and infrastructure monitoring. You’ll understand why this open source system has continued to gain popularity in recent years.
You will:
Know where and how much instrumentation to apply to your application code
Monitor your infrastructure with Node Exporter and use new collectors for network system pressure metrics
Get an introduction to Grafana, a popular tool for building dashboards
Use service discovery and the new HTTP SD monitoring system to provide different views of your machines and services
Use Prometheus with Kubernetes and examine exporters you can use with containers
Discover Prom’s new improvements and features, including trigonometry functions
Learn how Prometheus supports important security features including TLS and basic authentication
From the Preface
This book describes in detail how to use the Prometheus monitoring system to monitor, graph, and alert on the performance of your applications and infrastructure. This book is intended for application developers, system administrators, and everyone in between.
Expanding the Known
When it comes to monitoring, knowing that the systems you care about are turned on is important, but that’s not where the real value is. The big wins are in understanding the performance of your systems.
By performance we don’t only mean the response time of and CPU used by each request, but the broader meaning of performance. How many requests to the database are required for each customer order that is processed? Is it time to purchase higher throughput networking equipment? How many machines are your cache misses costing? Are enough of your users interacting with a complex feature in order to justify its continued existence?
These are the sorts of questions that a metrics-based monitoring system can help you answer, and beyond that help you dig into why the answer is what it is. We see monitoring as getting insight from throughout your system, from high-level overviews down to the nitty-gritty details that are useful for debugging. A full set of monitoring tools for debugging and analysis includes not only metrics, but also logs, traces, and profiling; but metrics should be your first port of call when you want to answer systems-level questions.
Prometheus encourages you to have instrumentation liberally spread across your systems, from applications all the way down to the bare metal. With instrumentation you can observe how all your subsystems and components are interacting, and convert unknowns into knowns.
The Evolution of Prometheus
As Prometheus has crossed the 10-year mark, this second edition brings new developments across all sections. Prometheus has continued to evolve and expand, offering even more options for scraping, storing, and querying data. This progress is a result of the dedicated community of users and contributors who use Prometheus across a wide and growing range of industries and applications.
The second edition of this book provides coverage of the many new PromQL functions, service discovery providers, and Alertmanager receivers that have been added since the first edition.
A new dedicated chapter covers server-side security features, such as TLS, that have been added to Prometheus and some of the exporters.
Review
“Julien an Bryan have been absolutely key in developing Prometheus, and their deep expertise is reflected in this book. It offers valuable practical advice for deploying and using Prometheus in real-world scenarios.” -Julius Volz, co-founder of Prometheus and founder of Promlabs
“With best practices and instrumentation advide directly from core Prometheus developers, this book will help you monitor your services with confidence.” -TJ Hoplock, Senior Observability SRE, NS1
