Cacti is a powerful network monitoring tool that allows you to collect and display data about your network’s performance. Using RRDTool, it stores and visualizes data in graphs, making it easier for administrators to track network usage, bandwidth, and other metrics over time. This article will guide you through the installation of Cacti on Ubuntu 24.04 and 22.04.
Prerequisites
Before you begin, ensure you have the following:
- An Ubuntu 24.04 or 22.04 server.
- A user account with sudo privileges.
- A LAMP (Linux, Apache, MySQL, PHP) stack installed on your server.
