RabbitMQ Essentials. - Second Edition

By: Lovisa Johansson, David Dossot

Overview of this book

RabbitMQ is an open source message queuing software that acts as a message broker using the Advanced Message Queuing Protocol (AMQP). This book will help you to get to grips with RabbitMQ to build your own applications with a message queue architecture. You’ll learn from the experts from CloudAMQP as they share what they've learned while managing the largest fleet of RabbitMQ clusters in the world. Following the case study of Complete Car, you’ll discover how you can use RabbitMQ to provide exceptional customer service and user experience, and see how a message queue architecture makes it easy to upgrade the app and add features as the company grows. From implementing simple synchronous operations through to advanced message routing and tracking, you’ll explore how RabbitMQ streamlines scalable operations for fast distribution. This book will help you understand the advantages of message queue architecture, including application scalability, resource efficiency, and user reliability. Finally, you’ll learn best practices for working with RabbitMQ and be able to use this book as a reference guide for your future app development projects. By the end of this book, you’ll have learned how to use message queuing software to streamline the development of your distributed and scalable applications.

Monitoring – querying the REST API

There are two main ways to retrieve live information when monitoring a RabbitMQ broker: one through the rabbitmqctl command-line tool and another through the REST API exposed over HTTP by the management console.

Any monitoring system can use these tools to collect metrics and report them to the log, analytics, reporting, and alert frameworks. Information could be pushed to external logging services for further analysis, as an example.

Since CC installed the management console, as described in Chapter 1, A Rabbit Springs to Life, the team opts to use the rich, well-documented API over the command line. RabbitMQ provides documentation at the http://localhost:15672/ API on any node that has the management plugin installed. It is possible to retrieve the same raw metrics over the command line, albeit without graphics.

Keep in mind that the management console is backed by the API, so anything that is seen and done within a browser can be done through...
