RabbitMQ Cookbook

Overview of this book

RabbitMQ is an open source message broker software (sometimes called message-oriented middleware) that implements the Advanced Message Queuing Protocol (AMQP). The RabbitMQ server is written in the Erlang programming language and is built on the Open Telecom Platform framework for clustering and failover. Messaging enables software applications to connect and scale. Applications can connect to each other as components of a larger application or to user devices and data. RabbitMQ Cookbook touches on all the aspects of RabbitMQ messaging. You will learn how to use this enabling technology for the solution of highly scalable problems dictated by the dynamic requirements of Web and mobile architectures, based for example on cloud computing platforms. This is a practical guide with several examples that will help you to understand the usefulness and the power of RabbitMQ. This book helps you learn the basic functionalities of RabbitMQ with simple examples which describe the use of RabbitMQ client APIs and how a RabbitMQ server works. You will find examples of RabbitMQ deployed in real-life use-cases, where its functionalities will be exploited combined with other technologies. This book helps you understand the advanced features of RabbitMQ that are useful for even the most demanding programmer. Over the course of the book, you will learn about the usage of basic AMQP functionalities and use RabbitMQ to let decoupled applications exchange messages as per enterprise integration applications. The same building blocks are used to implement the architecture of highly scalable applications like today's social networks, and they are presented in the book with some examples. You will also learn how to extend RabbitMQ functionalities by implementing Erlang plugins. This book combines information with detailed examples coupled with screenshots and diagrams to help you create a messaging application with ease.

Monitoring RabbitMQ's behavior


In order to check the correct behavior of RabbitMQ, it is useful to have a monitoring tool, especially when dealing with a cluster.

There are many different tools, commercial and freeware, which help to keep things under control in distributed systems such as Nagios and Zabbix.

In this recipe, we will show how to configure the RabbitMQ plugin for Ganglia (http://sourceforge.net/apps/trac/ganglia/wiki/ganglia_quick_start).

Getting ready

In order to run this recipe, you need to have RabbitMQ configured with the management plugin enabled.

You need to install and configure Ganglia too. In this recipe, we have used version 3.6.0.

How to do it...

In order to see RabbitMQ statistics within Ganglia monitoring graphs, you need to perform the following steps:

  1. Install and configure Ganglia using yum or apt-get depending on your Linux distribution. You will need the following packages:

    • ganglia-gmetad

    • ganglia-gmond

    • ganglia-gmond-python

    • ganglia-web

    • ganglia

  2. Copy the Python Ganglia monitor...
