Introduction

MRTG (Multi Router Traffic Grapher) is a powerful tool for monitoring network traffic and other performance metrics. It can be used to create graphs and reports that show how your network is performing over time. In this video tutorial, we will show you how to install and use MRTG to monitor your network.

Prerequisites

Before you can install MRTG, you will need to have the following:
A web server (such as Apache or Nginx)
PHP
SNMP (Simple Network Management Protocol)

Installation

To install MRTG, you can follow these steps:1. Download the MRTG source code from the official website.
2. Unpack the source code and change to the new directory.
3. Run the following commands to configure and compile MRTG:
```
./configure
make
```
4. Install MRTG by running the following command:
```
make install
```

Configuration

Once MRTG is installed, you will need to configure it. The configuration file is located at /etc/. Here is an example of a basic MRTG configuration file:```
# MRTG configuration file
# Define the web server port
webserver_port 8080
# Define the location of the MRTG data directory
data_dir /var/lib/mrtg
# Define the location of the MRTG log file
log_file /var/log/mrtg/
# Define the default target for MRTG graphs
default_target traffic
# Define the targets that MRTG will monitor
target traffic {
title Daily Traffic
graph daily
host myhost
port 161
community public
# Define the OIDs that MRTG will monitor
ifInOctets {
ds traffic_in
type ifCounter
}
ifOutOctets {
ds traffic_out
type ifCounter
}
}
```

Running MRTG

Once MRTG is configured, you can run it by issuing the following command:```
/usr/bin/mrtg /etc/
```
This will create the MRTG graphs and reports. You can view the graphs and reports by pointing your web browser to the MRTG web server. The default port for the MRTG web server is 8080.
