NetFlow Monitoring: See What Uses Your Bandwidth

Network engineers can now see which hosts, applications and conversations use their bandwidth. Atatus Network Monitoring collects flow records from your routers and switches through the Atatus Infrastructure Agent and breaks traffic down by source, destination, port and protocol.

Use flow data to find top talkers, spot unusual traffic, plan capacity and troubleshoot slow links, next to device health and your application data.

NetFlow Monitoring: See What Uses Your Bandwidth

What NetFlow monitoring gives you

  • Common flow formats: The Atatus Infrastructure Agent 4.2.0 or later listens for NetFlow v5, NetFlow v9, IPFIX and sFlow v5 records on the UDP ports you choose.
  • Traffic analysis: Break traffic down by source, destination, protocol and port to see exactly how bandwidth is used.
  • Top talkers: Find the hosts and conversations that send and receive the most traffic across your network.
  • Readable flows: Reverse DNS adds hostnames to flow records, and namespaces keep sites with overlapping private IP ranges apart.
  • Unusual traffic: Spot unexpected traffic spikes or protocols that may point to a misconfiguration or a security threat.
  • Capacity planning: Use historical traffic trends to plan network upgrades before links run out of bandwidth.
