The request accepts the following data in JSON format.

Note

In the following list, the required parameters are described first.

Identifier

An immutable identifier for a data source that is unique within an AWS Region. Performance Insights gathers metrics from this data source. To use an Amazon RDS DB instance as a data source, specify its DbiResourceId value. For example, specify db-ABCDEFGHIJKLMNOPQRSTU1VWZ.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 256.

Pattern: ^[a-zA-Z0-9-]+$

Required: Yes

Metrics

The types of metrics for which to retrieve dimensions. Valid values include db.load.

Type: Array of strings

Array Members: Minimum number of 1 item. Maximum number of 5 items.

Length Constraints: Minimum length of 0. Maximum length of 256.

Pattern: ^[a-zA-Z0-9-_\.:/*)( ]+$

Required: Yes

ServiceType

The AWS service for which Performance Insights returns metrics.

Type: String

Valid Values: RDS | DOCDB

Required: Yes

AuthorizedActions

The actions to discover the dimensions you are authorized to access. If you specify multiple actions, then the response will contain the dimensions common for all the actions.

When you don't specify this request parameter or provide an empty list, the response contains all the available dimensions for the target database engine whether or not you are authorized to access them.

Type: Array of strings

Array Members: Minimum number of 0 items. Maximum number of 3 items.

Valid Values: DescribeDimensionKeys | GetDimensionKeyDetails | GetResourceMetrics

Required: No

MaxResults

The maximum number of items to return in the response. If more items exist than the specified MaxRecords value, a pagination token is included in the response so that the remaining results can be retrieved.

Type: Integer

Valid Range: Minimum value of 0. Maximum value of 25.

Required: No

NextToken

An optional pagination token provided by a previous request. If this parameter is specified, the response includes only records beyond the token, up to the value specified by MaxRecords.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 8192.

Pattern: ^[a-zA-Z0-9_=-]+$

Required: No
