Testing Sentry SDK against Lambda functions

To test Sentry SDK integration with Node lambda function, follow the below steps.
  • Create development package from the source code
  • Upload it into Lambda console
  • Refer usage for use case specific handling

Create a development package

1. Clone the git repo on your development machine
2. Cloned repo contains multiple folders, each of these folder contains an example of how we can capture errors/exceptions on sentry dashboard
3. Go to any folder and edit the node source file. Edit below section of the file where you replace 'dsn' with your own DSN
Sentry.init({
  dsn: "<your DSN>",
});
4. Install the dependencies using following command.
npm install
5. Zip the contents of the folder so that it can be uploaded to lambda
$zip -r filename.zip *

Upload Zip file to Lambda function on AWS.

Create a Lambda function in Node by uploading the zip file created in 'creating development package' section with LambdaAdminAccess and test event configured. For more information refer to Node Lambda function.

Usage

1. Initialization error:

This function contains code that instruments lambda initialization error. This is instrumented by calling undefined function before invoking the Lambda handler.

Configuration: Set the following parameters in Lambda dashboard for Initialization error :
a) Handler : initialization.handler 
b) Timeout : 1 min

2. Handled exception:

This function contains code that instruments handled the exception.

Configuration: Set the following parameters in Lambda dashboard for handled exception :
a) Handler : handled_exception.handler

3. Network error:

This function contains code that instruments the network error using different scenarios.

Scenario: Wrong IP address

In this scenario, we put the wrong IP address.

Configuration: Set the following parameters in Lambda dashboard for wrong IP address scenario :
a) Handler : network_error_wrong_address.handler
b) Timeout : 10 sec

Scenario: Wrong PORT number

In this scenario, we put the wrong PORT number.

Configuration: Set the following parameters in Lambda dashboard for wrong PORT number scenario :
a) Handler : network_error_wrong_port.handler 
b) Timeout : 10 sec

4. Custom tags & Context:

This function contains code that instruments the handled exception and creates custom tag & context.

Configuration: Set the following parameters in Lambda dashboard for Custom tags & Context:
a) Handler : custom_tag_and_context.handler
b) Environment Variables :-
   Key : ENV_VAR
   Value : env_variable_value
