pi_get_resource_metrics: Retrieve Performance Insights metrics for a set of data sources, over a time period

Description

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.

Each response element returns a maximum of 500 bytes. For larger elements, such as SQL statements, only the first 500 bytes are returned.

Usage

pi_get_resource_metrics(ServiceType, Identifier, MetricQueries,
  StartTime, EndTime, PeriodInSeconds, MaxResults, NextToken)

Value

A list with the following syntax:

list(
  AlignedStartTime = as.POSIXct(
    "2015-01-01"
  ),
  AlignedEndTime = as.POSIXct(
    "2015-01-01"
  ),
  Identifier = "string",
  MetricList = list(
    list(
      Key = list(
        Metric = "string",
        Dimensions = list(
          "string"
        )
      ),
      DataPoints = list(
        list(
          Timestamp = as.POSIXct(
            "2015-01-01"
          ),
          Value = 123.0
        )
      )
    )
  ),
  NextToken = "string"
)

Arguments

ServiceType

[required] The AWS service for which Performance Insights returns metrics. The only valid value for ServiceType is RDS.

Identifier

[required] 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, specify its DbiResourceId value. For example, specify db-FAIHNTYBKTGAUSUZQYPDS2GW4A.

MetricQueries

[required] 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.

StartTime

[required] 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.

EndTime

[required] The date and time specifying 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.

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.

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.

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.
