Thundra

Monitor and debug your AWS Lambda functions with LocalStack and Thundra.

Overview

This guide describes how you can monitor and debug your AWS Lambda functions with Thundra.

Integrating Thundra with LocalStack

Supported languages

Currently only Node.js, Python and Java Lambdas are supported in this integration - support for other runtimes (.NET, Go) is coming soon.

LocalStack comes with out-of-the-box support for Thundra. Simply obtain a Thundra API key here and add it to your Lambda function’s environment variables (THUNDRA_APIKEY):

• AWS SAM
• AWS CDK
• Serverless Framework

Resources:
  MyFunction:
    Type: AWS::Serverless::Function
    Properties:
      // other function properties
      Environment:
        Variables:
          // other environment variables
          THUNDRA_APIKEY: <YOUR-THUNDRA-API-KEY>

const myFunction = new Function(this, "MyFunction", {
    ..., // other function properties
    environment: {
        ..., // other environment variables
        THUNDRA_APIKEY: <MY-THUNDRA-API-KEY>
    }
});

functions:
  MyFunction:
    // other function properties
    environment:
      // other environment variables
      THUNDRA_APIKEY: <YOUR-THUNDRA-API-KEY>

After invoking your AWS Lambda function, you can inspect the invocations and traces in the Thundra Console. You can find more details in the Thundra documentation.
