The Network Map is a Flash representation of your network's layer 3 topology. You can see the status of the devices on your network by noting the background color of the devices. You can select a particular device or network by double clicking on its icon in the map. This will center the map on the device or network and show the links from this node based on the number of hops selected. The same result is achieved by typing the name of the device or network and clicking the "Refresh" button. Note that when you select a node what is actually displayed are the links that are currently loaded into the map it does not download new link data at that time.

To load/reload the link data for a particular node, double click on that node, select the number of hops and click the refresh button. You can also filter the devices shown by Device Class. For example, to show only Linux devices, select /Server/Linux in the Device Class Filter and click refresh.

You can also adjust the number of viewable hops from the selected device by using the Number of Hops slider in the top right corner. You can also spread out the icons on the map by using the Repulsion slider also in the top right corner. If you'd like to get more detail on the selected device or network, just click the Go to Status Page link in the top left corner.
