Extra info and code examples

The Multi Router Traffic Grapher is a tool primarily used to monitor the traffic load on network links (typically by using SNMP). MRTG generates HTML pages containing PNG images which provide a LIVE visual representation of this traffic. MRTG typically produces daily, weekly, monthly, and yearly graphs. In addition to monitoring via SNMP, MRTG can also generate graphs based on the output of any application, allowing one to generate graphs of anything that needs monitoring (for example, CPU and memory usage, email volumes, web hits, etc). For faster data collection, MRTG can also interface to RRDtool. The mrtg-contrib package contains the contributed scripts and configuration files that used to form part of the mrtg package.
