Expression
Use Expression
to filter in various Cost Explorer APIs.
Not all Expression
types are supported in each API. Refer to the
documentation for each specific API to see what is supported.
There are two patterns:
-
Simple dimension values.
-
There are three types of simple dimension values:
CostCategories
,Tags
, andDimensions
.-
Specify the
CostCategories
field to define a filter that acts on Cost Categories. -
Specify the
Tags
field to define a filter that acts on Cost Allocation Tags. -
Specify the
Dimensions
field to define a filter that acts on theDimensionValues
.
-
-
For each filter type, 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
. ForGetRightsizingRecommendation
, the Region is a full name (for example,REGION==US East (N. Virginia)
. -
The corresponding
Expression
for this example is as follows:{ "Dimensions": { "Key": "REGION", "Values": [ "us-east-1", "us-west-1" ] } }
-
As shown in the previous example, lists of dimension values are combined with
OR
when applying the filter.
-
-
You can also set different match options to further control how the filter behaves. Not all APIs support match options. Refer to the documentation for each specific API to see what is supported.
-
For example, you can filter for linked account names that start with "a".
-
The corresponding
Expression
for this example is as follows:{ "Dimensions": { "Key": "LINKED_ACCOUNT_NAME", "MatchOptions": [ "STARTS_WITH" ], "Values": [ "a" ] } }
-
-
-
Compound
Expression
types with logical operations.-
You can use multiple
Expression
types and the logical operatorsAND/OR/NOT
to create a list of one or moreExpression
objects. By doing this, you can filter by more advanced options. -
For example, you can filter by
((REGION == us-east-1 OR REGION == us-west-1) OR (TAG.Type == Type1)) AND (USAGE_TYPE != DataTransfer)
. -
The corresponding
Expression
for this example 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"] }}} ] }
Note
Because each
Expression
can have only one operator, the service returns an error if more than one is specified. The following example shows anExpression
object that creates an error:{ "And": [ ... ], "Dimensions": { "Key": "USAGE_TYPE", "Values": [ "DataTransfer" ] } }
The following is an example of the corresponding error message:
"Expression has more than one roots. Only one root operator is allowed for each expression: And, Or, Not, Dimensions, Tags, CostCategories"
-
Note
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
.
