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.


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 (Multi-Router Traffic Grapher) is an open-source network monitoring and graphing tool. It is used to monitor network traffic and generate graphical reports of the data. In order to use MRTG, the following technical requirements must be met:

• A UNIX or Windows-based operating system such as Linux, FreeBSD, Windows 7, or Windows 10.

• A web server such as Apache or IIS installed on the server.

• SNMP (Simple Network Management Protocol) enabled on the network devices being monitored.

• Perl 5.6 or higher installed on the server.

• RRDtool (Round-Robin Database Tool) installed on the server.

• A compatible web browser such as Firefox, Chrome, or Internet Explorer.

MRTG is an open source software that is used primarily for monitoring network bandwidth usage. It is easy to use and setup, and can be used to monitor multiple devices. The software has a web interface, which makes it easy to access and check the data. I have found the graphs generated by MRTG to be very useful in detecting sudden increases in bandwidth usage, allowing me to quickly identify the potential causes. The software also allows for the setting of alert thresholds, so I can be quickly notified if bandwidth usage exceeds a certain level. I have also used MRTG to monitor disk space and CPU utilization on servers. It is a very reliable tool that I would recommend to anyone monitoring their network.
