AWS Performance Insights
API Reference (API Version 2018-02-27)

GetResourceMetrics

Retrieve Performance Insights metrics for a set of data sources, over a time period. You can provide specific dimension groups and dimensions, and provide aggregation and filtering criteria for each group.

Request Syntax

{ "EndTime": number, "Identifier": "string", "MaxResults": number, "MetricQueries": [ { "Filter": { "string" : "string" }, "GroupBy": { "Dimensions": [ "string" ], "Group": "string", "Limit": number }, "Metric": "string" } ], "NextToken": "string", "PeriodInSeconds": number, "ServiceType": "string", "StartTime": number }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Note

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

EndTime

The date and time specifiying the end of the requested time series data. The value specified is exclusive - data points less than (but not equal to) EndTime will be returned.

The value for EndTime must be later than the value for StartTime.

Type: Timestamp

Required: Yes

Identifier

An immutable, AWS Region-unique identifier for a data source. Performance Insights gathers metrics from this data source.

To use a DB instance as a data source, you specify its DbiResourceId value - for example: db-FAIHNTYBKTGAUSUZQYPDS2GW4A

Type: String

Required: Yes

MetricQueries

An array of one or more queries to perform. Each query must specify a Performance Insights metric, and can optionally specify aggregation and filtering criteria.

Type: Array of MetricQuery objects

Array Members: Minimum number of 1 item. Maximum number of 15 items.

Required: Yes

ServiceType

The AWS service for which Performance Insights will return metrics. The only valid value for ServiceType is: RDS

Type: String

Valid Values: RDS

Required: Yes

StartTime

The date and time specifying the beginning of the requested time series data. You can't specify a StartTime that's earlier than 7 days ago. The value specified is inclusive - data points equal to or greater than StartTime will be returned.

The value for StartTime must be earlier than the value for EndTime.

Type: Timestamp

Required: Yes

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 20.

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

Required: No

PeriodInSeconds

The granularity, in seconds, of the data points returned from Performance Insights. A period can be as short as one second, or as long as one day (86400 seconds). Valid values are:

  • 1 (one second)

  • 60 (one minute)

  • 300 (five minutes)

  • 3600 (one hour)

  • 86400 (twenty-four hours)

If you don't specify PeriodInSeconds, then Performance Insights will choose a value for you, with a goal of returning roughly 100-200 data points in the response.

Type: Integer

Required: No

Response Syntax

{ "AlignedEndTime": number, "AlignedStartTime": number, "Identifier": "string", "MetricList": [ { "DataPoints": [ { "Timestamp": number, "Value": number } ], "Key": { "Dimensions": { "string" : "string" }, "Metric": "string" } } ], "NextToken": "string" }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

AlignedEndTime

The end time for the returned metrics, after alignment to a granular boundary (as specified by PeriodInSeconds). AlignedEndTime will be greater than or equal to the value of the user-specified Endtime.

Type: Timestamp

AlignedStartTime

The start time for the returned metrics, after alignment to a granular boundary (as specified by PeriodInSeconds). AlignedStartTime will be less than or equal to the value of the user-specified StartTime.

Type: Timestamp

Identifier

An immutable, AWS Region-unique identifier for a data source. Performance Insights gathers metrics from this data source.

To use a DB instance as a data source, you specify its DbiResourceId value - for example: db-FAIHNTYBKTGAUSUZQYPDS2GW4A

Type: String

MetricList

An array of metric results,, where each array element contains all of the data points for a particular dimension.

Type: Array of MetricKeyDataPoints objects

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

Errors

For information about the errors that are common to all actions, see Common Errors.

InternalServiceError

The request failed due to an unknown error.

HTTP Status Code: 500

InvalidArgumentException

One of the arguments provided is invalid for this request.

HTTP Status Code: 400

NotAuthorizedException

The user is not authorized to perform this request.

HTTP Status Code: 400

Example

Retrieve Data Points for All Dimensions Within a Group

The following example requests data points for the db.wait_event dimension group, and for the db.wait_event.name dimension within that group. In the response, the relevant data points are grouped by the requested dimension (db.wait_event.name).

Sample Request

POST / HTTP/1.1 Host: <Hostname> Accept-Encoding: identity X-Amz-Target: PerformanceInsightsv20180227.GetResourceMetrics Content-Type: application/x-amz-json-1.1 User-Agent: <UserAgentString> X-Amz-Date: <Date> Authorization: AWS4-HMAC-SHA256 Credential=<Credential>, SignedHeaders=<Headers>, Signature=<Signature> Content-Length: <PayloadSizeBytes> { "ServiceType": "RDS", "Identifier": "db-LKCGOBK26374TPTDFXOIWVCPPM", "MetricQueries": [ { "Metric": "db.load.avg", "GroupBy": { "Group": "db.wait_event", "Dimensions": ["db.wait_event.type"] } } ], "StartTime": 1527026400, "EndTime": 1527080400, "PeriodInSeconds": 300 }

Sample Response

HTTP/1.1 200 OK Content-Type: application/x-amz-json-1.1 Date: <Date> x-amzn-RequestId: <RequestId> Content-Length: <PayloadSizeBytes> Connection: keep-alive { "AlignedEndTime": 1.5270804E9, "AlignedStartTime": 1.5270264E9, "Identifier": "db-LKCGOBK26374TPTDFXOIWVCPPM", "MetricList": [ { "Key": { "Metric": "db.load.avg" }, "DataPoints": [ { "Timestamp": 1527026700.0, "Value": 1.3533333333333333 }, { "Timestamp": 1527027000.0, "Value": 0.88 }, <...remaining output omitted...> ] }, { "Key": { "Metric": "db.load.avg", "Dimensions": { "db.wait_event.name": "wait/synch/mutex/innodb/aurora_lock_thread_slot_futex" } }, "DataPoints": [ { "Timestamp": 1527026700.0, "Value": 0.8566666666666667 }, { "Timestamp": 1527027000.0, "Value": 0.8633333333333333 }, <...remaining output omitted...> ], }, <...remaining output omitted...> ] }
