hello-world-nodejs

Description

A simple AWS Lambda function written and tested with Node.js 12.x and 14.x. The function is wrapped with the SignalFX Lambda wrapper to send telemetry to the Splunk Observability cloud.

Deployment

1. Create a new AWS Lambda function specifying Node.js 12.x or 14.x.

2. Once the function is created, and the signalfx-lambda-nodejs-wrapper layer to the function. This is done by specifying the ARN of the SignalFX Lambda Node.js Wrapper layer which can be found by visiting https://github.com/signalfx/lambda-layer-versions/blob/master/node/NODE.md.

   NOTE: Be sure to select the wrapper that matches the region your Function is deployed in.

3. Under the Configuration tab for your function, add the following Environment variables:

   • SIGNALFX_ACCESS_TOKEN: <YOUR_SPLUNK_ACCESS_TOKEN>
   • SIGNALFX_ENDPOINT_URL: https://ingest.<YOUR_SPLUNK_REALM>.signalfx.com/v2/trace

4. Under the Test tab, specify a event with the JSON payload as:

   {
     "data": "This is the data",
     "options": "https://splunk.com"
   }

Execution

Click the Test button. The Log output should like something like this:
