IIS Express is mainly used during the Development Process of .NET based applications. In order to use the dynaTrace .NET and Web Server Agent (for UEM) with IIS Express it is necessary to follow the following steps:
Enable dynaTrace for IIS Express 7.5
Step 1: Disable Logging
IIS Express will fail to launch in case an extension loaded into IIS writes log messages to the system output. In order to disable dynaTrace logging set the following two environment variables for IIS Express. As IIS Express is often launched by Visual Studio you have to set these variables for Visual Studio. You can also set this system-wide to avoid any problems:
Step 2: Configure .NET Agent through .NET Configuration Tool
Use the .NET Agent Configuration tool and configure iisexpress.exe to connect to your System Profile.
Step 3: Configure dynaTrace Web Server Modules for UEM
If you want to use dynaTrace UEM with IIS Express you have to configure the dynaTrace Web Server Module in the applicationHost.config file. This config file tells IIS Express which modules to load. Its default location is C:\Users\<username>\Documents\IISExpress\config\applicationhost.config. Add the following two lines:
In section <globalModules> add
In section <modules> add:
IIS Express 8
As of this writing (March 2012) IIS Express 8 is in Beta. IIS Express 8 will come in both 32 and 64 bit as compared to IIS Express 7.5. If you run IIS Express 8 in 64bit you have to load the 64bit version of the dtiisagent7.dll module which is located under "<dynaTrace install>\agent\lib64\dtiisagent7.dll"
