Powershell command to list all the app pool settings including recycling and advanced properties

Is there a powershell command to list all the app pool settings including recycling and advanced properties? I looked at the applicationhost file and that is not helpful. I would like to create a report using Powershell of all app settings as I need them to be all uniformed. There did not seem to be many scripts out there that listed all properties to achieve this. Has anyone successfully done this before?
