The Network Map represents your network's Layer 3 topology. From the map, you can quickly determine the status of each device by its background color.
Figure 2.8. Zenoss Network Map
Double-click a device or network icon in the map to focus on it. Focusing on a node:
Centers it on the map
Shows links from the node, based on the number of hops selected
Alternatively, you can type the name or IP address of a device or network in the Selected Device or Network field, and then click Refresh to focus on that node.
When you select a node, the network map displays only the links that are currently loaded into the map. It does not download and display new link data.
To load link data for a node:
Double-click the node on the map to focus on it, or enter the device name or IP address in the Selected Device or Network field.
Select the number of hops to download and display.
You can filter the devices that appear on the network map. To do this, select a filter from the Device Class Filter list of options. For example, to show only Linux devices on the map, select /Server/Linux from the list of options, and then click Refresh.
You can adjust the number of hops that appear on the network map. Use the Number of Hops slider, which adjusts the number of hops from 1 to 4.
Use the Repulsion slider to expand or contract the icons that appear on the map. Move the slider right to expand the icons, or left to contract them.
Select the Fit to Window option to bring all displayed icons into the viewable area.
To see detailed information about a device or network, select it in the map, and then click Go to Status Page.
Zenoss offers two types of menus from which you make selections:
Page menus extend the tabs that appear at the top of the page. Generally, actions initiated through a page menu affect the object or objects that the page represents. This could be, for example, a device or any group of devices.
As shown in the following figure, the Page menu is expanded next to the Classes tab.
