Determine the right size of NTA Flow Storage drive

Updated August 29, 2018

Overview

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

Environment

NTA version 4.0 through 4.2.3 (64-bit)

Steps

Automatic:

  1. Log in to the SolarWinds Orion Web Console > click Settings > All Settings.
  2. Under Product Specific Settings, click NTA Settings > Database Settings > NTA Flow Storage Database Settings.
  3. Click Calculate next to Database Size.

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

 

Manual:

  1. Log in to the SolarWinds Orion Web Console > click Settings > All Settings.
  2. Under Product Specific Settings, click NTA Settings > Database Settings > NTA Flow Storage Database Settings > Location > Remote Access that Server. 
  3. On the NTA Flow Storage databaser server, click Start > Search > NTA Flow Storage Configurator. 
  4. Launch the 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.
    TN#2016-04-11@0_0 
  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

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 file rate will be different if you add more interfaces to be monitored.
