MinimalLambda.Example.OpenTelemetry

📚 View Full Documentation

Getting Started

You may need to CD into this directory before running the following commands.

cd ./examples/MinimalLambda.Example.OpenTelemetry

Dependencies

These are the requirements to run this example:

Jaeger

Start Jaeger

docker compose up

This should start Jaeger on http://localhost:16686.

Lambda Local Emulator

The Lambda Local Emulator is used to run the Lambda function locally. It can be started with the following command:

dotnet lambda-test-tool start --lambda-emulator-port 5050 --config-storage-path "./events"

Running the Lambda function

The Lambda function can be run with the following command:

dotnet run

Invoking an event

Once the Lambda Local Emulator and the function are running, you can invoke an event by opening the UI and pasting the following JSON into the "Function Input" box:

{
  "Name": "John"
}

Instead, a sample event has been saved and should be available in the "Example Requests" dropdown menu.

You should then be able to see the trace in Jaeger. If you don't, give it a few seconds to propagate or stop your lambda function with ctrl+c, this will trigger shutdown with includes a force flush of traces and metrics.
