Testing OpenTelemetry instrumentation for AWS SDK for JavaScript

aws-sdk-js-otel-test

This sample shows how to use @opentelemetry/instrumentation-aws-sdk to instrument listTables call on DynamoDB client in AWS SDK for JavaScript.

The example exports spans data to Console. You can also export it to Jaeger by setting JAEGER_ENABLED environment variable.

Prerequisites

Complete the following tasks:

• Install Node.js by following these steps:
  1. Install nvm.
  2. Use node v16.x.x by running nvm use or nvm use 16 in a terminal window.
  3. Verify that node is installed by running node -v in a terminal window and confirm that it shows the latest version of v16, such as v16.15.0).
• Enable corepack by running corepack enable.
• Install dependencies by running yarn.
• If you don't have an AWS account, create one.
  • If you're an Amazon employee, see the internal wiki for creating an AWS account.
• Install the AWS CLI.
  • Verify that the AWS CLI is installed by running aws in a terminal window.
• Set up AWS Shared Credential File.
  • Your ~/.aws/credentials (%UserProfile%\.aws\credentials on Windows) should look like the following:

    [default]
    aws_access_key_id = <ACCESS_KEY>
    aws_secret_access_key = <SECRET_ACCESS_KEY>
    

  • Your ~/.aws/config (%UserProfile%\.aws\config on Windows) should look like the following:

    [default]
    region = us-west-2
    

• (Optional) Setup Jaeger Tracing: needs to be running on localhost port 16686.

Setup

The test code from this package uses AwsInstrumentation from @opentelemetry/instrumentation-aws-sdk to instrument listTables call on DynamoDB client.

Refer to the npm package for custom instrumentation options which can be passed.
