Overview of this book

RabbitMQ is one of the most powerful Open Source message broker software, which is widely used in tech companies such as Mozilla, VMware, Google, AT&T, and so on. RabbitMQ gives you lots of fantastic and easy-to-manage functionalities to control and manage the messaging facility with lots of community support. As scalability is one of our major modern problems, messaging with RabbitMQ is the main part of the solution to this problem This book explains and demonstrates the RabbitMQ server in a detailed way. It provides you with lots of real-world examples and advanced solutions to tackle the scalability issues. You’ll begin your journey with the installation and configuration of the RabbitMQ server, while also being given specific details pertaining to the subject. Next, you’ll study the major problems that our server faces, including scalability and high availability, and try to get the solutions for both of these issues by using the RabbitMQ mechanisms. Following on from this, you’ll get to design and develop your own plugins using the Erlang language and RabbitMQ’s internal API. This knowledge will help you to start with the management and monitoring of the messages, tools, and applications. You’ll also gain an understanding of the security and integrity of the messaging facilities that RabbitMQ provides. In the last few chapters, you will build and keep track of your clients (senders and receivers) using Java, Python, and C#.

RabbitMQ command-line tools


RabbitMQ's powerful command-line tools have lots of skills, such as controlling, managing, and monitoring. One of the command-line tools of RabbitMQ, rabbitmqctl, gives us an opportunity to monitor the RabbitMQ in real-time. We use the rabbitmqctl tool for its monitoring functions, such as reporting on the RabbitMQ and displaying the status and specific functions of RabbitMQ.

The report function of the rabbitmqctl tool shows lots of details of RabbitMQ in realtime. The report function shows the sum of all monitoring results of the other functions of rabbitmqctl. We can find the running environment variables, configuration parameters, and cluster statuses, as shown in the next command block.

Moreover, the report function shows the current state of each functional structure of RabbitMQ, such as connections to RabbitMQ, channels in RabbitMQ, and so on, as shown in the following code:

Cluster status of node rabbit@localhost ...
[{nodes,[{disc,[rabbit@localhost]}]},
...
