Netflow Service high CPU utilization

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


NTA version 4.1.1 



This issue occurs because the primary polling engine can only handle 50,000 flows per second.


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