GetMetricData is used to retrieve metric data-sets from CloudWatch. Excessively high numbers of GetMetricData calls are often due to 3rd-party tooling or services (such as DataDog and similar services) that are using CloudWatch data to create dashboards and other visualizations.

You can enable logging for CloudWatch data-api's to CloudTrail and then you will be able to review CloudTrail and see the identify of the caller making these calls, and knowing that make changes that could reduce the number of calls.
