Wrapping your Lambda

• Wrap your lambda function by implementing a supplier which contains your code:

using Lumigo.DotNET;
using Lumigo.DotNET.Instrumentation;
...
public class Function : LumigoRequestHandler
    {
        public Function()
        {
            LumigoBootstrap.Bootstrap();
        }

        public async Task<string> FunctionHandler(string input, ILambdaContext context)
        {
            return await Handle(input, context, async () =>
            {
                //Your lambda code
                //return <result>;
            });
        }
    }

• For handler return void use:

using Lumigo.DotNET;
using Lumigo.DotNET.Instrumentation;
...
public class Function : LumigoRequestHandler
    {
        public Function()
        {
            LumigoBootstrap.Bootstrap();
        }

        public async Task FunctionHandler(string input, ILambdaContext context)
        {
            return await Handle(input, context, async () =>
            {
                //Your lambda code
            });
        }
    }

Configuration

Environment variables

• Add LUMIGO_TRACER_TOKEN environment variable.

Building and Deployment using the Serverless framework

• Make sure you have dotnet installed on your machine by running brew install --cask dotnet.
• Create a .Net project template by running sls create -t aws-csharp -n hello-world .. This command will create a .net template for a service named hello-world in current directory.
• Add Lumigo.DotNET as a dependency of the project.
• Wrap the lambda handler using Lumigo.DotNET.
• Run ./build.sh in the created template directory. The command will build the zip artifact for the Lambda.
• Run sls deploy to deploy your lambda. Pay attention Each time you are changing the code you need to run ./buid.sh and then sls deploy, in case you are only changing the serverless.yml run sls deploy.
