Expression
Use Expression to filter in the GetFreeTierUsage API operation.
You can use the following patterns:
-
Simple dimension values (
Dimensionsroot operator) -
Complex expressions with logical operators (
AND,NOT, andORroot 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": [
{"Or": [ {"Dimensions": { "Key": "REGION", "Values": [ "us-east-1", "us-west-1" ],
"MatchOptions": ["EQUALS"] }}, {"Dimensions": { "Key": "SERVICE", "Values": ["AWSLambda"], "MatchOptions": ["CONTAINS"] } } ]}, {"Not": {"Dimensions": { "Key": "USAGE_TYPE", "Values": ["DataTransfer"], "MatchOptions": ["CONTAINS"] }}} ] }
In the following Contents, you must specify exactly one of the following root operators.
