Overview

Use ‘Expression` to filter in the `GetFreeTierUsage` API operation.

You can use the following patterns:

  • Simple dimension values (‘Dimensions` root operator)

  • Complex expressions with logical operators (‘AND`, `NOT`, and `OR` root operators).

For *simple dimension values*, you can set the dimension name, values, and match type for the filters that you plan to use.

**Example for simple dimension values**

You can filter to match exactly for ‘REGION==us-east-1 OR REGION==us-west-1`.

The corresponding ‘Expression` appears like the following: `{ “Dimensions”: { “Key”: “REGION”, “Values”: [ “us-east-1”, “us-west-1” ], “MatchOptions”: [“EQUALS”] } }`

As shown in the previous example, lists of dimension values are combined with ‘OR` when you apply the filter.

For *complex expressions with logical operators*, you can have nested expressions to use the logical operators and specify advanced filtering.

**Example for complex expressions with logical operators**

You can filter by ‘((REGION == us-east-1 OR REGION == us-west-1) OR (SERVICE CONTAINS AWSLambda)) AND (USAGE_TYPE !CONTAINS DataTransfer)`.

The corresponding ‘Expression` appears like the following: `{ “And”: [ [ {“Dimensions”: { “Key”: “REGION”, “Values”: [ “us-east-1”, “us-west-1” ], “MatchOptions”: [“EQUALS”] }, {“Dimensions”: { “Key”: “SERVICE”, “Values”: [“AWSLambda”], “MatchOptions”: [“CONTAINS”] } } ]}, {“Dimensions”: { “Key”: “USAGE_TYPE”, “Values”:

“DataTransfer”], “MatchOptions”: [“CONTAINS”

}} ] }‘

In the following Contents, you must specify exactly one of the following root operators.
