MRTG - Multi Router Traffic Grapher is a piece of program which was originally designed to measure SNMP queries from routers and graph the results without having to keep too much information yet still provide some idea about the line status.
Today MRTG has evolved many times and has reached a level where almost anything can be monitored if you get the correct data sorted the way MRTG expects to get is.
If you have a router, Windows server, Linux server, switch or any other device even if it does not support SNMP get the data correctly and you will get a nice graph.
