MRTG juga dikenal sebagai "Multi Router Traffic Grapher" adalah tool yang free dan open source untuk memantau beban lalu lintas pada jaringan. Kita dapat memonitor lalu lintas jaringan harian, mingguan, bulanan, dan tahunan menggunakan MRTG. MRTG mendukung sistem operasi Windows dan Linux. MRTG menyediakan antarmuka web sederhana untuk menampilkan data lalu lintas jaringan dalam bentuk grafis.
