NTA Sources Library

NTA Sources Library (SETTINGS menu > Network Traffic Analysis > NTA Sources) enables you to view and manage Netflow and NTA sources.

Tip: If you are using WhatsUp Gold and Network Traffic Analysis for the first time, it is important to understand that if you have NetFlow sources already active on your network these sources will display in the NTA Sources Library table automatically. To begin receiving flow data on an active source, click Edit and then enable it.

• Add NBAR/QoS Source. Add endpoints for gathering NBAR classification statistics.
• Add Aggregated Source. Organize interfaces into aggregate groups (Creating Aggregate Sources, Aggregating Sources).
• Edit. Edit the selected NTA source, flow source, or aggregated interface (Creating Aggregate Sources, Aggregating Sources).
• Delete. Delete the NTA source, flow source, or aggregated interface.
• Access Rights. Scope user access to view and share traffic data.
• Source Traffic. Access NTA results data and dashboard views.

Understanding Column Data

Each source record in the NTA Source Library has the following fields:

• Name. Name of source device.
• Enabled. Indicates if flow or statistics are gathered from this device.
• Protocol. Flow protocol (if supported).
• Credentials. Credential types. You can add additional credentials using the WhatsUp Gold Credential Library.
• Receiving Flows. Indicates if flow source is active. ("n/a" indicates not a configured flow source).
• Flow Rate. Flow packet rate.
• Traffic Totals. Indicates if traffic totaling is active. Flow Sum denotes traffic totals are summed from NetFlow packets. Receiving indicates traffic totals are estimated (typical of sFlow).
• NBAR Polling. Indicates if endpoint is polled for NBAR classification data (fetched by SNMP).
• NBAR Embedded. Indicates if NBAR is provided by the NetFlow protocol.
• ASN Embedded. Indicates if ASN (Autonomous System Number) identification is provided by the current flow protocol.
• Last Active. Time of last information.

Click a column heading () to display the column selection listing . You can also include:

• IP Address. Device IP address.
• Reliability. Estimated reliability based on the volume and sampling rate.
• Sample Rate. Fraction of observed traffic data reported by source.
