Integration Options for .NET SDK

Upgrading from v1.x to 2.x
In v2.x, we've made some changes to our agent as we've started to support .NET Core 2.1 applications as well. 

If you are using the Thundra agent v1.x already, make sure to check what needs to be changed here.

Step 1: Add Thundra NuGet package
The .NET Thundra agent can be easily downloaded with the command shown below:
1
dotnet add package Thundra.Agent --version $LATEST_VERSION
Copied!
Latest Version
Similarly, you can add the agent via the NuGet Package Manager of your IDE (if available). For example, Visual Studio allows you to add packages through the IDE itself; a simple search for Thundra .NET will allow you to procure and add the correct agent to your project.
Step 2: Change serverless.yml
You should replace all of your handlers to “Thundra.Agent::Thundra.Agent.Lambda.Core.ThundraProxy::Handle” and set the real handler path as a separate environment variable.
serverless.yml

  FirstFunction:
5
    handler: Thundra.Agent::Thundra.Agent.Lambda.Core.ThundraProxy::Handle

    environment:

      thundra_agent_lambda_handler: <your_handler>
8
      thundra_apiKey: <your_api_key>

  SecondFunction:

    handler: Thundra.Agent::Thundra.Agent.Lambda.Core.ThundraProxy::Handle

      thundra_agent_lambda_handler: <your_second_handler>
14
      thundra_apiKey: <your_api_key>
15
​
16
...
Copied!
Using this method, you can connect Thundra to your functions by modifying the configuration files without needing to change your code. The ThundraProxy class will call the actual handler as soon as it receives the request.
Serverless Plugin
Step 1: Install Thundra’s Serverless Plugin
1
npm install serverless-plugin-thundra
Copied!
Step 2: Add Thundra's Serverless Plugin in the serverless.yml File 

After installing Thundra’s serverless plugin, you need to add it under the plugins section of your serverless.yml file in order to specify it as a plugin for your serverless environment.
serverless.yml
1
plugins:  
2
    - serverless-plugin-thundra
Copied!
Step 3: Add thundra Component to Custom
Add the thundra component under custom with the apiKey beneath that, as shown below:
serverless.yml
1
custom:
2
    thundra:
3
        apiKey: <YOUR THUNDRA API KEY>
Copied!
Step 4: Deploy and Test the App
1
serverless deploy
2
serverless invoke --function functionName
Copied!
Step 5: Monitor Your Function with Thundra
After generating your first invocation, the “Next” button will appear in the Invocation Monitor bar. Simply click the button to see monitoring data from your invocation.

{

16
                Code = Code.FromAsset("path/to/function/package"),
17
                Handler = "Thundra.Agent::Thundra.Agent.Lambda.Core.ThundraProxy::Handle",

                Environment = new Dictionary<string, string>
19
                {

                    ["thundra_apiKey"] = thundraApiKey,

                    ["thundra_agent_lambda_handler"] = "Your.Assembly::Your.Type::YourMethod"
22
                }
23
            });
24
        }
25
    }
26
}
Copied!
​
Step 2: Build and Deploy
1
dotnet build src && cdk deploy
Copied!
Step 3: Invoke Your Function
Now you can invoke your Lambda function and see the details of your invocation in the Thundra console!
Step 1: Add the Thundra NuGet Package
The .NET Thundra agent can be easily downloaded with the command shown below:
1
dotnet add package Thundra.Agent --version $LATEST_VERSION
Copied!
Latest Version
Similarly, you can add the agent via the NuGet Package Manager of your IDE (if available). For example, Visual Studio allows you to add packages through the IDE itself; a simple search for Thundra .NET will allow you to procure and add the correct agent to your project.
Step 2: Change the Handler's Code
Extend Thundra's LambdaRequestHandler within your handler class and then override the DoHandleRequest method, which encapsulates your handler code. LambdaRequestHandler takes two generic classes as parameters: the type of request object and the type of response object.
Function.cs
1
using Amazon.Lambda.Core;
2
using Thundra.Agent.Lambda.Core;
3
​
4
namespace ThundraSample
5
{
6
    public class Function : LambdaRequestHandler<string, string>
7
    {
8
​
9
        /// <summary>
10
        /// Handler class needs to extend `LambdaRequestHandler< Request, Response >`
11
        /// Please write all code within the DoHandleRequest method
12
        /// </summary>
13
        /// <param name="request"></param>
14
        /// <param name="context"></param>
15
        /// <returns>/Greeting Message/</returns>
16
        public override string DoHandleRequest(string request, ILambdaContext context)
17
        {
18
            return "Hello Thundra";
19
        }
20
    }
21
}
Copied!
Step 3: Change Your Handler to Thundra's HandleRequest
Next, you should change your handler to <MyAssembly>::<MyNamespace>.<MyClass>::HandleRequest.
It is a common mistake to utilize the hook method DoHandleRequest as the handler. In order to initialize Thundra, you must change your handler to HandleRequest, which resides in the base class (LambdaRequestHandler).
