Documentation

Use Expression to filter by cost or by usage. There are two patterns:

• Simple dimension values - You can set the dimension name and values for the filters that you plan to use. For example, you can filter for REGION==us-east-1 OR REGION==us-west-1. For GetRightsizingRecommendation, the Region is a full name (for example, REGION==US East (N. Virginia). The Expression example is as follows:

  { "Dimensions": { "Key": "REGION", "Values": [ "us-east-1", “us-west-1” ] } }

  The list of dimension values are OR'd together to retrieve cost or usage data. You can create Expression and DimensionValues objects using either with* methods or set* methods in multiple lines.

• Compound dimension values with logical operations - You can use multiple Expression types and the logical operators AND/OR/NOT to create a list of one or more Expression objects. By doing this, you can filter on more advanced options. For example, you can filter on ((REGION == us-east-1 OR REGION == us-west-1) OR (TAG.Type == Type1)) AND (USAGE_TYPE != DataTransfer). The Expression for that is as follows:

  { "And": [ {"Or": [ {"Dimensions": { "Key": "REGION", "Values": [ "us-east-1", "us-west-1" ] }}, {"Tags": { "Key": "TagName", "Values": ["Value1"] } } ]}, {"Not": {"Dimensions": { "Key": "USAGE_TYPE", "Values": ["DataTransfer"] }}} ] }

  Because each Expression can have only one operator, the service returns an error if more than one is specified. The following example shows an Expression object that creates an error.

   { "And": [ ... ], "DimensionValues": { "Dimension": "USAGE_TYPE", "Values": [ "DataTransfer" ] } }

For the GetRightsizingRecommendation action, a combination of OR and NOT isn't supported. OR isn't supported between different dimensions, or dimensions and tags. NOT operators aren't supported. Dimensions are also limited to LINKED_ACCOUNT, REGION, or RIGHTSIZING_TYPE.

For the GetReservationPurchaseRecommendation action, only NOT is supported. AND and OR aren't supported. Dimensions are limited to LINKED_ACCOUNT.

Create a value of Expression with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:not:Expression', expression_not - Return results that don't match a Dimension object.

$sel:and:Expression', expression_and - Return results that match both Dimension objects.

$sel:or:Expression', expression_or - Return results that match either Dimension object.

$sel:costCategories:Expression', expression_costCategories - The filter that's based on CostCategory values.

$sel:dimensions:Expression', expression_dimensions - The specific Dimension to use for Expression.

$sel:tags:Expression', expression_tags - The specific Tag to use for Expression.

Return results that don't match a Dimension object.

Return results that match both Dimension objects.

Return results that match either Dimension object.

The filter that's based on CostCategory values.

The specific Dimension to use for Expression.

The specific Tag to use for Expression.
