S3BucketsUsageMetricPublisher

A construct that creates an AWS Lambda function to publish S3 General Purpose buckets usage metrics to CloudWatch.

Usage

To use the S3BucketsUsageMetricPublisher construct, simply import it into your AWS CDK stack and create a new instance of the construct:

import { Stack } from 'aws-cdk-lib';
import { S3BucketsUsageMetricPublisher } from './s3-buckets-usage-metric-publisher';

const stack = new Stack(app, 'MyStack');

new S3BucketsUsageMetricPublisher(stack, 'MyS3BucketsUsageMetricPublisher', {
  publishFrequency: 5,
  cwNamespace: 'MyNamespace',
});

This will create a new AWS Lambda function that publishes the number of S3 bucket to CloudWatch every 5 minutes for the us-east-1 and us-west-2 regions, using the MyNamespace namespace.
