- From the web interface, click . The GO menu appears.
- If the WhatsUp section is not visible, click . The WhatsUp section of the GO menu appears.
- Select . The Discovery Console appears.

- Open the Discovery Console.
- From the console main menu, select . The Discovery Console appears.
Before you can run a discovery scan on your network, you need to configure the discovery settings. The Discovery Settings are located in the Settings column on the left side of the Discovery Console. You can also use the WhatsUp Gold Welcome Center Setup Assistant to step through the discovery setting options.
After running a discovery, use the following sections of the Discovery Console to manage and view discoveries:
Select Discovery Settings
WhatsUp Gold can use several different methods to scan your network. Select the scan type that best fits your network topology.
Select your scan type preference to discover network devices.
- . This scan type uses an SNMP enabled router to identify the devices in a network and also identifies sub-networks within the network.
- . Enter the IP addresses that indicate where you want to start the network discovery scan. The discovery engine reads SNMP data from these devices and continues to scan the network for additional devices based on the SNMP responses from the seed devices.
- . Click to enter a new seed address for the discovery scan.
- . Select a seed address to change.
- . Select a seed address to delete.
- . Enter an integer value that defines how deep discovery should scan to find network devices. This sets the levels of your network that you want to scan. With a value of 1, the scan discovers and maps your top-level network and any sub-networks of that top-level. To discover a sub-network within that sub-network, you must enter a scan depth of 2 or greater. The default value of 2 means that the scan discovers and maps the top-level network and two sub-network levels.
- . Enter the IP range that defines the addresses to include in the network scan. For example, 10.0.0.1 and 10.0.0.100.
- . Click (console) or (web interface) to browse to the
Hosts
file location. Discovery scans and imports the IP addresses mapped to host names listed in the Hosts
text file. You can also select other text files that include a list of IP address.: If you update the Hosts
text file, you must click (console) or (web interface) to update the host file information. If you do not, the Hosts
file changes will not be updated for new Hosts File Scans.
SNMP Credentials
The SNMP credentials defined in the Credentials Library are listed as credential options for the discovery scan. Select the credential(s) to use for the discovery scan. If the credentials you want to use for discovery are not available, click to add new credentials. For more information, see the Credentials Library help.
Windows Credentials
The WMI credentials defined in the Credentials Library are listed as credential options for the discovery scan. Select the credentials to use for the discovery scan. If the credentials you want to use for discovery are not available, click to add new credentials. For more information, see the Credentials Library help.
Scan Method (Ping)
- . Select Ping or Advanced.
- . Uses a standard ICMP ping command to scan for network devices.
- . Enter the time, in seconds, for a device to respond to a ping scan. If it does not respond to the scan within this time, the scan continues on to the next IP address. The default is 2 seconds.
- . Enter the number of times to attempt to ping a device before continuing on to the next device. The default is 1 retry.
- . Uses TCP port checks to scan on networks where ICMP pings are disabled. This scan attempts to connect on an IP address's specific TCP ports. If the connection is successful, the device at that IP address is discovered.
Scan Advanced Settings
- . Enter the time, in seconds, for an SNMP device to respond. If it does not respond to the scan within this time, the scan continues on to the next IP address. The default is 2 seconds.
- . Enter the number of times to try to attempt to discover a device at a given IP address before continuing on to the next device.
- . Enter the time, in seconds, for a WMI device to respond. If it does not respond to the scan within this time, the scan continues on to the next IP address. The default is 10 seconds.
- . Select this option to populate the list of discovered devices with host names in addition to IP addresses.
. Click to start a new network discovery based on the discovery settings above.
