Configuring Direct Network Scan Audit Sources

You configure a Direct Network Scan Audit Source when you create a new Site, or create or modify an Audit Source within an existing Site. Before configuring a Direct Network Scan Audit Source, make sure you have configured a proper Audit Profile.

To create a Direct Network Scan Audit Source:

  1. In the Sidebar, right-click the Site where you want to create the audit source and select Properties from the pop-up menu.

  2. Under Audit Sources, click New > Direct Network Scan.

  3. Fill out the source details in the Direct Network Scan Audit Source [Source Name ] window.

  4. Click OK.

To edit the properties of an existing Direct Network Scan Audit Source, do the following:

  1. Open the Site, to which the source belongs, by right-clicking the Site in the Sidebar and selecting Properties from the pop-up menu.

  2. Double-click the source under Audit Sources.

  3. Modify the source as needed in the Direct Network Scan Audit Source [Source Name] window.

  4. Click OK.

Direct Network Scan Audit Source [Source Name ] window

The properties of Direct Network Scan Audit Source are shown in the Direct Network Scan Audit Source [Source Name ] window where they are organized on the following tabs: General and Options.

General tab

Here you can review and modify the basic properties of a Direct Network Scan Audit Source.

NOTE: Separate scheduling for the file scan is available if only the current Audit Profile has the File Scan option enabled or its Software Discovery option is set to Discover installed software and recognize software in files. For details, see Software Discovery, File Scan.

Options tab

On this tab, you can modify the method for discovering new computers and devices in the source.

  • Discovering - define the options for discovering IP addresses:

    • Discover only computers and devices that respond to ping requests - when selected, defines to discover only nodes that are available on the network.

    • Connection timeout - allows you to enter the maximum amount of time in milliseconds that will be used to establish connection with the target computer or device. If Network Inventory is unable to establish connection with a particular computer within the specified interval, that computer will be considered unavailable. Applicable to the IP Address Ranges only.

  • Enable SNMP discovery - when selected, enables discovery using SNMP in a Direct Network Scan Audit Source.
