NTA module does not load


This article provides brief information and steps on how to resolve the issue when NTA does not load, or takes a while to load. 


  • NTA versions 3.11 - NTA 4.1.1
  • NPM versions 11.0.1 - NPM 11.5.2
  • Server 2008 - Server 2012


The issue is caused by Thwack or Netflow Sources that add to the NTA Summary page by default, and the volume of interfaces of queries that run real time for each interface.


  1. Go to the NTA Summary view.
  2. Click Customize Page on the top right.
  3. Remove Thwack resource or NetFlow Sources.
  4. Test the NTA performance.
