NetFlow pages slowly load when displaying multiple pages

Updated April 25, 2017

Overview

NetFlow pages take a long time to display when loading multiple pages. The NetFlow Flow Storage server memory usage shows 90-100% capacity, and then drops after the pages have loaded. 

Environment

NTA 4.x 

Cause 

This behavior occurs when there is not enough RAM. A larger NetFlow database memory is needed to load multiple pages at the same time or load large data sets, such as data sets with longer time periods. The NetFlow Flow Storage server uses memory when performing these actions even if it normally displays a low usage level.

Resolution

SolarWinds recommends adding server memory to increase the RAM.

As an additional enhancement, you can move the NetFlow Flow Storage swap file.
