Cloudfront Invalidation Metrics

CloudFront Invalidation Metrics offer users with access to CloudWatch dashboards some interesting new graphs which show the following custom metrics:

• Invalidation count per CloudFront distribution ID
• Paths selectively invalidated per CloudFront distribution ID.

How to

The Lambda can be run locally as a Go binary without the Lambda variables _LAMBDA_SERVER_PORT or AWS_LAMBDA_RUNTIME_API being set like normal:

go run main.go

It will however need to authenticate to AWS in the standard way, so set the following variables as needed to authenticate.

	Variable	Explaination
Configuration file	AWS_CONFIG_FILE	Configuration file for AWS to use Defaults to `${HOME}/.aws/credentials.
Profile	AWS_PROFILE	Name of the profile to use in your configuration file.
Region	AWS_REGION	The regional identifier - such as ap-southeast-2.
Access Key ID	AWS_ACCESS_KEY_ID	The access key ID from your IAM credentials.
Secret Access Key	AWS_SECRET_ACCESS_KEY	The secret access key from your IAM credentials.

Examples

1. Providing credentials to the app:

   AWS_ACCESS_KEY_ID=x AWS_SECRET_ACCESS_KEY=y go run main.go

2. Providing credentials via profile to the app:

   AWS_PROFILE=z go run main.go
