NTA Source Library (SETTINGS menu > Network Traffic Analysis > NTA Sources) provides a table view of:

• Flow sources detected on your network.
• Flow sources you configured manually or automatically using NTA Device Configuration.
• Devices polled for NBAR traffic totals.
• Groups or individual interfaces providing SNMP or flow statistics.

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.
