- ASP.NET Core 1.x or 2.x running on Windows
- Support for ASP.NET Core 3.x and Linux coming soon
Installing the Agent
STEP 1 - Download the installer
Download the Raygun Agent on the server you would like to monitor
STEP 2 - Install the agent
Open the agent installer you downloaded and follow the on-screen prompts to install the agent
STEP 3 - Input your API key
Launch the Raygun Profiler Configuration tool. You'll need an API key to register the agent. Create a new application in Raygun if you have not already, and navigate to the APM set up screen to find your API key.
Under the Agent tab of the configuration tool, set the Default API key and then Register the Agent.
STEP 4 - Attach to a .NET Core process
Open the .NET Core tab in the Raygun Profiler Configuration tool.
If your .NET Core application is running then you can select it from the process list.
If your process is not listed then find the path to your process dll or exe and enter it into the assembly name field.
With your .NET Core process selected, click the Register button, then enter your Raygun application API Key into the dialog and click Save.
STEP 5 - Register the profiler
There are many ways in which a .NET Core application can be started, so we've listed some common methods along with the required environment variables needed to configure the Raygun APM profiler correctly. To view these options, click the Show Config button from the configuration screen:
Select the appropriate option from that list, and set your environment variables. Now everything is configured. Make a few requests to your application and traces should appear within Raygun after a couple of minutes. If they don't appear, try running status checks and running a profiler test below.
Installing using the Raygun CLI tool
Another method for registering and profiling a .NET Core application is to use the Raygun CLI tool
1. Register your .NET Core process with the Raygun application API Key using the following command.
# Configure HelloWorldApp.dll with an API Key rgc.exe -enable HelloWorldApp.dll -type dotnetcore -apikey xxx -startup 30 -norecycle
2. To start the process and automatically configure the correct environment variables you can bootstrap the execution of your .NET Core process using the following command.
# Start HelloWorldApp.dll process with profiler environment configured rgc.exe -profile "%ProgramFiles%\dotnet\dotnet.exe" -arguments HelloWorldApp.dll -coreclr -apikey <APP-API-KEY> -startup 60
Deregistering an application
1. To stop profiling a .NET Core application you'll first need to remove the environment variables that were configured when your application starts. Once these have been removed, restart your application to stop profiling.
2. The final step is to remove the API Key configuration by going to the .NET Core tab in the Raygun Profiler Configuration tool. Select the configured process and click the Deregister button.
