Ipswitch WhatsUp Gold User Guide
The source identifying information is displayed and in some cases can be edited:
Source. The device (source) IP address.
Flow Protocol. Indicates the flow protocol used by the source device.
Display Name. The device (source) display name.
To enable or disable data collection from a source:
1 Select Enable data collection from this source to start receiving data from a newly
configured, or previously disabled source. (Default).
2 Deselect Enable data collection from this source, to stop receiving data from this
source.
Note: You must deselect Enable data collection from this source to delete a source. When
you delete a source, you will no longer receive data from the source. All data you have
collected prior to deleting the source will be maintained in the Flow Monitor database until
it is aged out.
To use SNMP polling to collect data from the source:
1 In the SNMP Polling group, select the credential that is valid for the interface from the
list, or click the browse (...) button to go to the Credentials Library to configure a new set
of credentials.
Note: If you select a different set of credentials, the dialog automatically uses the new
credentials to update information about the source interfaces. If you receive an error, click
Advanced to update timeout and retry values, then click Query to try the credentials again.
Advanced. Click to configure the device (source) SNMP timeout and retry settings.
Query. Click to use the updated retry and timeout values for the selected SNMP
credential.
2 If you want to poll the source for total interface traffic, select Poll source for total
interface traffic.
Important: When you poll a source for interface traffic, the aggregate of the individual flows
is not used to represent total interface traffic. Instead the polled value is used to represent
total interface value.
Important: When a sampled flow protocol is being used that does not supply total interface
traffic statistics, you can select Poll source for total interface traffic to provide these
statistics.
Note: When a source uses packet sampling to collect flow data and the protocol does not
provide total interface traffic statistics, the aggregate of individual flow data used to
calculate total interface traffic will be inaccurate because the data used in the calculation is
sampled, this commonly results in errors in total interface traffic statistics.
