Overview of NetSight Element Manager

IP or Host Locator

An additional tool linked to but run separately from the Discover application allows you to resolve host names to IP addresses, and vice versa. You can also discover the IP addresses and host names of all devices located on a subnet, and locate both the IP and hostname for a device by its MAC address.

Automatic Creation of the Node Database

Your discovered nodes are automatically entered into NetSight Element Manager’s central node database, and the Discover window remains open so that you can view the list of discovered devices. The database is also automatically saved after each discovery.

Secondary Discover and Discover Reset

The first time you run a device discover script, all IP addresses in the subnet or address range you have specified will be queried, and all discovered devices will be listed in the discover window and automatically added to the central node database. This is called a NEW Discovery. The second time you run any device discover, however — even a device script which has not yet been run —NetSight Element Manager will perform a SECONDARY Discover, querying only those IP addresses which did not respond to the first discover. This process allows you to use a discover script to periodically survey a subnet, domain, or range of IP addresses for any nodes that might have been down or simply not present during the initial discovery, without the time and bandwidth cost of continually re-polling for nodes which have already been successfully discovered. You can force a return to NEW Discovery mode by clicking the Reset button in the Discover Manager window; deleting any node from the central database will also reset the device script counters to NEW Discovery mode.

Discover Wizard

A Wizard is provided to walk you through each step of configuring and performing a discovery.

The Discover application is covered in Chapter 3, Discovering Nodes.

Management and Monitoring Workspace

NetSight Element Manager provides four work areas that allow you to choose how to view information about the devices in your central node database: the List View, Tree View, Map View, and Log View. Each provides a slightly different (and user-configurable) look at the central node database, each comes with default views to get you started, and each provides you with the ability to create one or more views specifically designed to display the node information you need to successfully manage your network.

The following sections highlight each of these workspaces, and provide sample illustrations of the workspaces and the windows available from them.
