Discovering Nodes

Accessing the Discover Manager window; creating and modifying Discover scripts; executing Discover
scripts; the Discover process; starting the Discover Wizard; launching the Scheduler application; using
the IP or Host Locator; using the Subnets window

The Discover Manager application allows you to locate devices on a network. You can
perform a Discover process within a specified range of IP (Internet Protocol) addresses, on
an entire subnet, or on a combination of the two. The Discover application automatically
explores the defined network segment, creates a list of discovered devices, and assigns an
icon to each of them. The discovered nodes are then automatically integrated into
NetSight Element Manager’s central node database, and consequently displayed as
appropriate in any List or Tree Views (see Chapter 4,

List Views

, and Chapter 5,

Tree

Views

, for more information).

The Discover application operates using scripts, which are created and saved within the
application (allowing them to be run repeatedly if desired). You can create a new Discover
script by using either the Discover Manager window (

Figure 3-1

) or the Discover Wizard,

which will lead you step by step through the Discover process (see

Starting the Discover

Wizard

on

page 3-19

). The following sections describe the use of the Discover Manager

window to create, modify, and execute Discover scripts.

Accessing the Discover Manager Window

To access the Discover Manager window from the NetSight Element Manager primary
window:

1. Select

Tools —> Discover Manager

from the primary window menu bar.

or

Click the Discover Manager button (

) on the NetSight Element Manager

Standard toolbar.

The Discover Manager window,

Figure 3-1

, opens.
