NetFlow Service high CPU utilization

Overview

This article describes the issue when the NetFlow service is causing high CPU utilization on the server.

Environment

NTA version 4.1.1

Cause 

This issue occurs because the Main Polling Engine can only handle 50,000 flows per second.

Resolution

  1. Run Performance Monitor on the server to check flows per second. 
  2.  Unmanage some devices in NTA. 
  3. Recommend an additional poller to balance the load.
