Get IIS Application Pool Failure Settings Using PowerShell

Using GUI from the IIS Manager, you can get the Application Pool Failure settings using App pool advanced settings from the Rapid-Fail Protection section as shown below.

To retrieve the above settings using PowerShell,

To run the above command we need the IISAdministration module. You can retrieve the same settings using the WebAdministration module and using IIS PSDrive.
