In this tutorial, we will activate and learn how to manage URL rewrites using Apache2’s `mod_rewrite` module. This tool allows us to rewrite URLs in a cleaner fashion, translating human-readable paths into code-friendly query strings.
In this part of the “Building for Production: Web Applications” series (5 of 6), we will add monitoring to improve our awareness of the state of our servers and services. Monitoring software, such as Nagios, Icinga, and Zabbix, enables you to create dashboards and alerts that will show you which components of your application setup need attention. The goal of this is to help you detect issues with your setup, and start fixing them, before your users encounter them.
