    How can I monitor network traffic and bandwidth usage?

    SolarWinds® NetFlow Traffic Analyzer (NTA) monitors network traffic patterns and bandwidth usage across hybrid and distributed networks. It gives you a high-level view of network utilization and lets you drill into traffic by application, protocol, endpoint, conversation, and IP address group.

    How can I find the applications and endpoints using the most bandwidth?

    NTA identifies top talkers, bandwidth-heavy applications, and endpoints generating large amounts of traffic. Color-coded graphs, charts, and filters help you see who is using your network, how much bandwidth they are consuming, and what the bandwidth is being used for.

    How can I troubleshoot network congestion and bandwidth bottlenecks?

    NTA helps you move from identifying a busy interface to finding the applications, endpoints, conversations, or protocols causing the traffic. Drill-down views and historical flow data help you isolate high-bandwidth usage, investigate unexpected traffic, and determine the root cause of network slowdowns.

    Can I analyze flow data from different network vendors?

    Yes. NTA can collect and analyze Cisco NetFlow v5 and v9, NBAR2, Juniper J-Flow, sFlow, IPFIX, and Huawei NetStream. This multi-vendor support lets you analyze network traffic from different flow-enabled devices through a centralized interface.

    Can I create custom network traffic views and reports?

    Yes. Flow Navigator lets you filter traffic and create personalized views based on details such as applications, protocols, and IP addresses. You can also generate in-depth network traffic reports and schedule automatic weekly delivery to your team.

    What do I need to start collecting flow data?

    Your network devices must support a compatible flow technology and be configured to export flow data to the NTA collector. Devices and their exporting interfaces must also be monitored through SolarWinds Network Performance Monitor. NTA listens for flow data on UDP port 2055 by default, although you can configure additional collection ports.
