When we last left our hero MRTG, he was doing simple SNMP Gets and spitting out some fairly basic graphs. While this is terribly useful already, MRTG (and sidekick Routers2.cgi) is capable of much more. In this installment of the MRTG article series, I will be demonstrating how to tap into the power of WMI to further enhance your MRTG experience.

Installing MRTG on a Windows Platform

MRTG is the most popular open source performance measuring tool being used around the world today. While MRTG is open source, it has been widely adopted by major companies everywhere who use it to measure network performance and adherence to SLAs, among other things. For an interesting snapshot of who is using MRTG, and for what purpose, go to MRTG’s “Where, What, How” page and have a look at some of the interesting things MRTG is being used to track. Although MRTG started out as an application to measure network performance on routers (MRTG stands for “Multi Router Traffic Grapher”), it is being used today to graph everything from traffic jams in the Netherlands to the local temperature in Wroclaw. If you can provide a numeric value to MRTG, it can produce a graph of it.
