Configure the App Agent for .NET properties using a single configuration file. This topic describes the structure and content of the config.xml file to help you customize agent behavior. To use the .NET Agent Configuration Utility, see Configure the App Agent for .NET.

Overview

The App Agent for .NET uses a single configuration file to control agent behavior: Controller connectivity, machine agent operations, and app agent functionality for IIS applications, Windows services, and standalone applications such as console applications, WinForms, or WPF. Benefits of the unified configuration file include:

  • Maintain agent configurations separately from web.config files.
  • Enable instrumentation of Windows services and standalone applications without environment variables.
  • Control agent behavior for specific applications with hierarchical configuration.

To configure connection to the Controller, See Controller Element.

To configure the .NET machine agent, See Machine Agent Element.

To configure app agents for IIS applications, see App Agents - IIS Element.

To configure an app agent for a Windows service, see App Agents - Windows Services Element.

To configure an app agent for a standalone application, see App Agents - Standalone Applications Element.

Where to Configure App Agent Properties

Configure the agent properties in the config.xml file in the agent Config directory. If you run the .NET Agent Configuration Utility, it writes the config.xml to the following locations:

Windows Server 2008 and later

%ProgramData%\AppDynamics\DotNetAgent\Config\config.xml

Windows Server 2003

%AllUsersProfile%\Application Data\AppDynamics\DotNetAgent\Config\config.xml

Sample config.xml files install to the following location:

%ProgramFiles%\AppDynamics\AppDynamics .NET Agent\SampleConfigurations

(warning) After you edit the config.xml, you must restart the AppDynamics.Agent.Coordinator service. Then restart IIS, your Windows service, or standalone application for your instrumentation changes to take effect.

Minimal .NET App Agent controller-info.xml File

The most basic configuration demonstrates the required sections for agent configuration. This sample instruments all IIS applications using the automatic element (<automatic />). No Windows services or standalone applications are instrumented.
