#2 PHP Weathermap

When you wish for an overview of your network traffic, PHP Weathermap is the best tool for it. It shows a logical map of your routers and the links between them, using different colors to indicate how busy each link is. PHP Weathermap is a good complement to an application such as Cacti or OpenNMS.

PHP Weathermap does not handle its own data collection, so you'll need to pair it with another application such as Cacti, OpenNMS, MRTG, or RRDtool. PHP Weathermap has a plug-in that helps it integrate into Cacti, with some options available in the Cacti preference panels.

You will need to edit the map config files to adjust the appearance of your maps. You can do this by hand, though PHP Weathermap offers a GUI editor that runs within a Web browser. You can use the editor to create your nodes (routers and switches) and links, as well as produce a functioning map.
