- Select . The New Device Discovery Wizard appears.
- Select as the method for scanning your network, then
click . The SNMP SmartScan
settings dialog opens.
- In the box, enter the IP address of the SNMP
enabled router you want to use for this scan.
- In the box, enter the proper read community string
for that router. If an incorrect string is entered, WhatsUp Gold
will be unable to scan the network. Additional community strings
may be entered, separated by commas, if there are multiple SNMP
enabled devices on your network that use different strings.
Optionally, select the Windows credential
that you want to use during discovery. These credentials are
configured in the Credentials Library, and store Windows
authentication information (username and password) for those
devices that require a logon for discovery or monitoring. Click the
Browse () button next to
this box to access the Credentials Library. You can select a
specific credential, select to try all credentials that are
configured or select to
ignore those devices that require you to log on. The credential
that is successful is associated with each device.
- Click the button if you want to change the
scan's default timeouts in milliseconds, retry counts, and scan
- Click to select the option
if you want to limit the scan to the network class (A, B, or C)
defined by the IP address of the root device. If the IP address is
within the network class of the root device, the scan proceeds.
Otherwise, the scan skips to the next IP address.
- Click to select the option if you want to
populate the list of discovered devices with host names in addition
to IP addresses.
- Click to save changes and return to the SNMP
SmartScan settings dialog.
- Click . The Active/Performance Monitors to
Scan dialog opens. Select the type of Active Monitor(s) and
Performance Monitor(s) you want to use in this scan process. Let's
select Ping and HTTP as our Active Monitors and Disk Utilization as
our Performance Monitor to be used in the scan process.
- The Ping monitor
polls the device on a regular basis to establish whether it is Up
or Down. By default, WhatsUp Gold sends a ping command to each
viable IP address in the range configured during the first section
of this wizard. If the device responds, WhatsUp Gold scans for the
monitors listed on this dialog. If the device does not respond,
discovery moves on to the next IP address. You can select
have device discovery scan each IP address for all of the selected
monitors without first sending the ping command to the device.
Discovery takes longer if this option is selected.
If you want a Ping monitor created for the devices found in
discovery, you must select as an active monitor to scan even if
you have cleared the option.
If a device only has one interface, WhatsUp Gold intentionally does
not add the Interface Active Monitor during discovery. Doing so
with the Ping Active Monitor would be redundant.
- The HTTP monitor
polls a web server (if one is discovered) on the device on a
regular basis to establish if it is Up or Down.
see how a monitor is configured, you can go to the Active Monitor
Library (), select a monitor, then click .
- The Disk Utilization
monitor monitors and reports on the available disk space for
the selected device. Data collected is displayed in the Disk
- Click . The Device Discovery displays the
estimated remaining scan time and the scan's progress. You can
cancel the Device Discovery by clicking .
- When the Discovery is over, the
opens, listing all of the devices just discovered. Note that if any
of the devices have already been entered into the database, a
shortcut to the device will be created in the device list. To add
all of the devices to the database, click . To remove specific devices to be
monitored from this list, clear the checkbox next to the device you
want to remove.
Additional Active Monitors and Performance Monitors that are
already in the database will not be added to devices.
- Click . The Action Policy Selection dialog
opens. For more information about Action Policies, see the About Action Policies
- Complete the remaining screens in the
The Results summary shows the number of
selected new devices, number of active and performance monitors,
whether or not an Action Policy is applied, and the number of
selected device shortcuts.
- Click to begin monitoring the devices.
A progress bar appears while devices are added to the database,
then the Device View opens. For more information about Device
Views, see About the Device View.
If some device group folders are empty, it is due to the fact that
although a subnet was found, the devices in the subnet were either
not scannable, or you chose not to monitor them.
