We explored Moodle and OS native tools, services, and reports that can be useful in monitoring the system health and reacting accordingly. The reader was presented with a detailed explanation of Moodle log and the ways it can be used. We also presented Linux and Windows native tools that offer deeper insight in the status of various system services (free disk space, RAM usage, CPU load, and so on.). Finally, we explained how to install and configure native statistics tool for integration with the web server—The Webalizer. After all this you should be able to understand and maintain your server in a much better condition.
