Don't you think the documentation for forwarding the logs from AWS CloudWatch to AppSignal lengthy?

Doc: https://docs.appsignal.com/logging/platforms/cloudwatch.html

Same here! But you are in luck, here's the script I used to do all steps at once!

You only need the AppSignal token (given after you created a new CloudWatch source) and the CloudWatch group log name (not the ARN).

The CloudWatch template: https://gist.github.com/D-system/6dc155100de058b8a7c4c58b136d5bf1

I provided their support with the template and invited them to add the CloudFormation template to their doc 😀 Let's see if it'll be added.
