  dynatrace-aws-s3-log-forwarder-configuration

  This template deploys log forwarding and log processing rules to be used by the dynatrace-aws-s3-log-forwarder
  AWS Lambda function using AWS AppConfig hosted configurations. The template is provided with a default forward all rule.
  You can modify this template to deploy your custom log forwarding and log processing rules that control the 
  behavior of the log forwarder. All changes are versioned in AWS AppConfig configuration profiles.

  NOTE: There's a limit of 1 MB of size per configuration profile.
