AWS Centralized Logging Solution

The AWS Centralized Logging Solution is a reference implementation that provides a foundation for logging to a centralized account. Customers can leverage the solution to index CloudTrail Logs, CW Logs, VPC Flow Logs on a ElasticSearch domain. The logs can then be searched on different fields.

Getting Started

To get started with the AWS Centralized Logging Solution, please review the solution documentation. https://aws.amazon.com/answers/logging/centralized-logging/

Running unit tests for customization

  • Clone the repository, then make the desired code changes
  • Next, run unit tests to make sure added customization passes the tests
cd ./deployment
chmod +x ./run-unit-tests.sh  \n
./run-unit-tests.sh \n

Building distributable for customization

  • Configure the bucket name of your target Amazon S3 distribution bucket
export TEMPLATE_OUTPUT_BUCKET=my-bucket-name # bucket where cfn template will reside
export DIST_OUTPUT_BUCKET=my-bucket-name # bucket where customized code will reside
export VERSION=my-version # version number for the customized code

Note: You would have to create 2 buckets, one with prefix 'my-bucket-name' and another regional bucket with prefix 'my-bucket-name-<aws_region>'; aws_region is where you are testing the customized solution. Also, the assets in bucket should be publicly accessible

  • Now build the distributable:
chmod +x ./build-s3-dist.sh \n
./build-s3-dist.sh $DIST_OUTPUT_BUCKET $TEMPLATE_OUTPUT_BUCKET $VERSION \n
  • Deploy the distributable to an Amazon S3 bucket in your account. Note: you must have the AWS Command Line Interface installed.
aws s3 cp ./dist/ s3://my-bucket-name/centralized-logging/<my-version>/ --recursive --exclude "*" --include "*.template" --include "*.json" --acl bucket-owner-full-control --profile aws-cred-profile-name \n
aws s3 cp ./dist/ s3://my-bucket-name-<aws_region>/centralized-logging/<my-version>/ --recursive --exclude "*" --include "*.zip" --acl bucket-owner-full-control --profile aws-cred-profile-name \n
  • Get the link of the centralized-logging-primary.template uploaded to your Amazon S3 bucket.
  • Deploy the AWS Centralized Logging Solution to your account by launching a new AWS CloudFormation stack using the link of the centralized-logging-primary.template.
