MRTG is a free, open-source tool designed to monitor and measure the traffic load on network links. It generates HTML pages containing graphical representations (PNG images) of network traffic, providing visual insights into bandwidth usage over time. Originally developed to monitor router traffic, MRTG has evolved to graph various network devices and other metrics.
Features
- Monitors SNMP-enabled network devices
- Generates HTML pages with traffic graphs
- Supports multiple operating systems, including Windows and UNIX
- Configurable data collection intervals
- Visualizes inbound and outbound traffic separately
- Can be extended to monitor various metrics beyond network traffic
