How to find source of GetMetricData

Hello Avinash,

Sorry for any frustration caused. You may find this article helpful in determining your CloudWatch Usage and costs: https://aws.amazon.com/premiumsupport/knowledge-center/cloudwatch-understand-and-reduce-charges/.

You can also refer to this doc for more details on cost and usage reports: https://docs.aws.amazon.com/cur/latest/userguide/how-cur-works.html.

If that's not quite what you need, you can always create a case with our Billing team to look into the cause of the charges: go.aws/support-center.

Best wishes,

• Marc O.

Thankyou Marco for your valuable inputs.

Data events in CloudTrail is able to log the API calls to CloudWatch metrics, including GetMetricData. You just need to create/modify a trail and add data events with the type CloudWatch metrics.
