This article provides steps to determine the right size of your NTA flow storage drive depending on your Flow storage retention settings.


NTA version 4.0 or later (64-bit)




  1. Login to the SolarWinds Web Console > Settings.
  2. Go to the product's specific Settings > NTA settings > Database Settings > NTA Flow storage Database Settings.
  3. Click Database Size > Calculate.

You should be able to see the size of your NTA database and the projected size based on your retention period.




  1. Login to SolarWinds Web Console > Settings.
  2. Go to the product's specific settings > NTA settings > Database Settings > NTA Flow storage Database Settings > Location > Remote Access that Server. 
  3. On the NTA flow storage server, click Start > Search > NTA flow storage configurator. 
  4. Launch NTA flow storage configurator, and copy the path where it saves.
  5. Open the flow folder, and copy all folders in the following format with the numbers being the date.
  6. Click the Date yesterday > All folder files, and right-click Properties.
  7. Check the Size of disk.
  8. Multiply it to the Database retention you have.
    Example: 1GB/day X 30 days (retention) = 30 GB


Note: This is if you did not add any new interfaces to be monitored on NTA in the last 30 days. The size of the disk and your rate of files getting will be different if you add more interfaces to be monitored.
