Cloudwatch Retention Setter

Cloudwatch Retention Setter is an AWS CDK construct library that reacts on AWS CloudWatch events. AWS CloudWatch does not offer the ability to set a "default retention policy" that would be set to all newly created Log Groups (e.g. by Lambda Function runs).

This construct addresses this by monitoring AWS CloudWatch Events via EventBridge, when a new LogGroup is created a Lambda function is invoked automatically that sets the retention policy to the specified value.

Getting started

const app = new cdk.App();
const stack = new cdk.Stack(app, '<stack-name>');
