The Multi Router Traffic Grapher (MRTG) is a tool to monitor the traffic load on network links. MRTG generates HTML pages containing PNG images which provide a LIVE visual representation of this traffic.
MRTG works on most UNIX platforms and Windows NT.
MRTG Uses a highly portable SNMP implementation written entirely in Perl . There is no need to install any external SNMP package.
Reliable Interface Identification
Router interfaces can be identified by IP address, description and Ethernet address in addition to the normal interface number.
