I don't work for AppD, so I can't assist you like their support can. However, I can tell you the basics. Extensions are free "add-ons" which you can setup in the "monitors" folder of an active AppD machine-agent (i.e. C:\AppD\machine-agent\machine-agent4.5.12\monitors). Once you have a machine-agent reporting into the Controller, it will auto-poll the monitors folder and grab any additional metrics the extensions tell it to. You can go into your Controller GUI, and find the extension metrics in the "metric browser" tab of your application/agent. Often times you'll need to expand out your Application > Tier > Node until you see a "Custom Metrics" folder. Your extension data will be there. The only exception is if you edit the extension's .xml file to have it report to a different location. This particular Azure extension appears to be an add-on for another extension, making it slightly unique. So in this instance, you'll not only need a machine-agent reporting in, but you'll also need the .Net Manager Extension as well. Instructions for installing the .Net Manager extension are here: https://www.appdynamics.com/community/exchange/extension/appdynamics-net-agent-extension-manager/ Once you have it setup, then follow the Azure directions here: https://www.appdynamics.com/community/exchange/extension/azure-monitor-net-extension/ Then log into the Controller and follow my "metric browser" advice above to find where these extensions are repoting in, and go from there. I hope that helps.
