How do you look at console.log output of the amazon lambda function

Question

When you do a

console.log('Loading function');

in an amazon lambda function, where does that go?

AWS Lambda logs are written to CloudWatch Logs. Here's how to access them:

1. select your Lambda function in the AWS console
2. click the Monitoring tab
3. choose View logs in CloudWatch

If you prefer to retrieve CloudWatch Logs outside of the AWS Console, then there are numerous CLI options:

• awscli: aws logs get-log-events
• github: jorgebastida/awslogs
• github: TylerBrock/saw
• serverless: sls logs (if using serverless)
• samcli: sam logs (if using SAM)
