MRTG (Multi Router Traffic Grapher) is a powerful and versatile open-source network monitoring tool used to track traffic load on network links. Developed by Tobias Oetiker,
MRTG is a free, open-source application that uses SNMP (Simple Network Management Protocol) to measure and monitor network traffic and generate detailed graphical reports.
Features
1. It can monitor wide range of network devices: MRTG is capable of monitoring any SNMP-enabled device, including routers, switches, servers, printers, and more.
2. It can monitor different interfaces: MRTG can monitor multiple interfaces on a single device, and it can also be used to monitor multiple devices at the same time.
3. It can monitor multiple values: MRTG can monitor not only the traffic load, but also other values such as CPU utilization, memory usage, and more.
4. It can generate detailed graphical reports: MRTG can generate detailed graphical reports, including line graphs, bar graphs, and histograms.
5. It can be used to set up alarms: MRTG can be used to set up alarms that can alert the user when a certain value exceeds a certain threshold.
6. It has support for multiple operating systems: MRTG can be used on multiple operating systems, including Linux, Windows, and Mac OS X.
7. It can be used in a distributed environment: MRTG can be used in a distributed environment, allowing multiple users to access the same data.
8. It is easy to install and configure: MRTG is relatively easy to install and configure.
9. It is highly scalable: MRTG is highly scalable, allowing you to monitor as many devices and interfaces as you need.
10. It is highly customizable: MRTG is highly customizable, allowing you to configure the data collection process, the reports, alarms, and more.
MRTG provides a way to monitor network performance over time, allowing for the identification of trends, performance issues, and capacity planning.
