ConsultNet Implement management tools that can be implemented and support locally or managed remotely over PSTN or ISDN services.

ConsultNet design and optimise MRTG scripts for Network trending for cost effective proactive long term trending that can be easily implemented as a management solution.

The Multi Router Traffic Grapher (MRTG) is a tool that monitors the traffic load on network-links. MRTG generates HTML pages containing GIF images which provide a LIVE visual representation of this traffic. MRTG is based on Perl and C and works under UNIX and Windows NT. MRTG is being successfully used on many sites around the net.

MRTG consists of a Perl script which uses SNMP to read the traffic counters of your routers and a fast C program which logs the traffic data and creates beautiful graphs representing the traffic on the monitored network connection. These graphs are embedded into webpages which can be viewed from any modern Web-browser.In addition to a detailed daily view, MRTG also creates visual representations of the traffic seen during the last seven days, the last four weeks and the last twelve months. This is possible because MRTG keeps a log of all the data it has pulled from the router. This log is automatically consolidated, so that it does not grow over time, but still contains all the relevant data for all the traffic seen over the last two years. This is all performed in an efficient manner. Therefore you can monitor 50 or more network links from any halfway decent box.

MRTG is not limited to monitoring traffic though, it is possible to monitor any SNMP variable you choose. You can even use an external program to gather the data which should be monitored via MRTG.

People are using MRTG, to monitor things such as System Load, Login Sessions, Modem availability and more. MRTG even allows you to accumulate two or more data sources into a single graph.Works on most UNIX platforms and Windows NT Uses Perl for easy customization Has a highly portable SNMP implementation written entirely in Perl. There is no need to install any external SNMP package. MRTG's logfiles do NOT grow. Thanks to the use of a unique data consolidation algorithm. MRTG comes with a semi-automatic configuration tool. MRTG's query engine checks for port reconfigurations on the router and warns the user when they occur.
