Overview of this book

Moodle is the de facto standard for open source learning platforms. However, setting up and managing a learning environment can be a complex task since it covers a wide range of technical, organizational, and pedagogical topics. This ranges from basic user and course management, to configuring plugins and design elements, all the way to system settings, performance optimization, events frameworks, and so on. This book concentrates on basic tasks such as how to set up and configure Moodle and how to perform day-to-day administration activities, and progresses on to more advanced topics that show you how to customize and extend Moodle, manage courses, cohorts, and users, and how to work with roles and capabilities. You’ll learn to configure Moodle plugins and ensure your VLE conforms to pedagogical and technical requirements in your organization. You’ll then learn how to integrate the VLE via web services and network it with other sites, including Mahara, and extend your system via plugins and LTI. By the end of this book, you will be able to set up an efficient, fully fledged, and secure Moodle system.

Built-in profiling

Moodle provides some basic profiling information that you can turn on in Development | Debugging, where you have to enable the Performance info option. This will display information about the execution time, RAM usage, number of files in use, CPU usage and load, session size, as well as various filter and caching measures (less information will be shown on a Windows-based installation).

It further displays information on the caches used in the particular page. For each cache, hits, misses, and sets are shown. The caches are highlighted using traffic light colors: red uses up the most, orange some, and green uses up the least amount of resources. This is a rather good indicator...
