This pattern uses a Python script to retrieve Amazon CloudWatch metrics and to convert the metrics information into a comma-separated values (CSV) file for improved readability. The script takes the AWS service whose metrics should be retrieved as a required argument. You can specify the AWS Region and AWS credential profile as optional arguments. If you don’t specify those arguments, the script uses the default Region and profile that are configured for the workstation where the script is run. After the script runs, it generates and stores a CSV file in the same directory.
