Check for Active Sources

NTA automatically detects flow sources it can reach and begins collecting flow data. To check to see if NTA is already gathering data from flow sources, open the NTA Sources Library (SETTINGS menu > Network Traffic Analysis > NTA Sources). Select a row and then click Source Traffic. This is the quickest route to begin seeing NTA data.

As soon as Network Traffic Analysis is up and running, WhatsUp Gold begins collecting flow statistics from source devices sending flow packets and populating the flow database, which you can analyze, apply to reports, and share. This procedure envisions that simple scenario.

1. Open the NTA Sources Library (SETTINGS menu > Network Traffic Analysis > NTA Sources).
2. Look for devices registered both as Enabled and Receiving packets from the flow exporter.
   • If you find an active and enabled flow device, select it in the grid and then click the Source Traffic button to the dashboard and reports related to this flow.
   • If you do not find an active flow source, you need to configure one. See the topic titled Check for Ready-to-Configure Sources.

Next Steps

Explore the dashboard, reports and capabilities of NTA:

• Select Interfaces and traffic reported.
• Aggregate traffic statistics flowing over specific interfaces (Creating Aggregate Sources, Aggregating Sources).
• Organize traffic by transport protocol and application port.
• Apply keyword, endpoint, and application filtering to reports.
• Scope and profile WhatsUp Gold user access to report data.
• Leverage NBAR (packet identification and inspection engine) from flow details or SNMP polls (with Flexible NetFlow, NBAR stats are already embedded in flow summaries)
• Audit class-based Quality of Service (QoS) measurements against policies.
• And much more.
