AppDynamics agents are plug-ins or extensions that monitor the performance of your Server, Database, and application. The agent collects data and sends it to the controller to analyze, report the issue and provide a beautiful dashboard for the customer or IT Support team.

Appdynamics provide a long list of agents. You will find the agent list on the AppDynamics site. I am providing the link here –

Out of which, we will see today how to install .DotNet agent on a Windows machine to monitor Applications. Let’s see what is pre-requisite for it.


  1. Administrative privilege on App server to install the agent
  2. The app server should have connectivity with the Controller
  3. Open ports: 8090, 9191,3388,8181, and 8080 from the controller server to the App server.
  4. The agent should have the same version of the Controller.
  5. node name should be unique
  6. length of application and tier should not be more than 500
  7. Avoid special characters in the name of nodes, tiers, and application.
