Overview of this book

Django is a high-level web framework that eases the creation of complex, database-driven websites. It emphasizes on the reusability and pluggability of components, rapid development, and the principle of don't repeat yourself. It lets you build high-performing, elegant web applications quickly. There are several Django tutorials available online, which take as many shortcuts as possible, but leave you wondering how you can adapt them to your own needs. This guide takes the opposite approach by demonstrating how to work around common problems and client requests, without skipping the important details. If you have built a few Django projects and are on the lookout for a guide to get you past the basics and to solve modern development tasks, this is your book. Seven unique projects will take you through the development process from scratch, leaving no stone unturned. In the first two projects, you will learn everything from adding ranking and voting capabilities to your App to building a multiuser blog platform with a unique twist. The third project tackles APIs with Django and walks us through building a Nagios-inspired infrastructure monitoring system. And that is just the start! The other projects deal with customizing the Django admin to create a CMS for your clients, translating your web applications to multiple languages, and using the Elasticsearch search server with Django to create a high performing e-commerce web site. The seventh chapter includes a surprise usage of Django, and we dive deep into the internals of Django to create something exciting! When you're done, you'll have consistent patterns and techniques that you can build on for many projects to come.

Chapter 3. Djagios – a Nagios Clone in Django

In this chapter, we'll be creating a server status monitoring solution similar to Nagios. It is understandable if you have never heard of Nagios as it is not something that comes up in day-to-day conversations between web developers. In a nutshell, Nagios can tell you the status of your servers (which can be in the thousands) in one screen. You can configure alerts based on conditions, for example, if some critical server becomes unresponsive, so that you can be on top of problems before your users start to notice any service degradation. Nagios is an amazing piece of software that is used by millions of organizations around the world.

Our goal in this chapter is to create something similar, albeit very simple. Our Nagios clone, creatively named Djagios, will allow users to set up monitoring for simple stats from their servers. We will allow the monitoring of the following:

  • System load

  • Disk usage

We will also be developing a web page where this data...
