Overview

Package pi provides the API client, operations, and parameter types for AWS Performance Insights.

Amazon RDS Performance Insights Amazon RDS Performance Insights enables you to monitor and explore different dimensions of database load based on data captured from a running DB instance. The guide provides detailed information about Performance Insights data types, parameters and errors. When Performance Insights is enabled, the Amazon RDS Performance Insights API provides visibility into the performance of your DB instance. Amazon CloudWatch provides the authoritative source for AWS service-vended monitoring metrics. Performance Insights offers a domain-specific view of DB load. DB load is measured as Average Active Sessions. Performance Insights provides the data to API consumers as a two-dimensional time-series dataset. The time dimension provides DB load data for each time point in the queried time range. Each time point decomposes overall load in relation to the requested dimensions, measured at that time point. Examples include SQL, Wait event, User, and Host.

Types

type Client 

type Client struct {
	// contains filtered or unexported fields
}

Client provides the API client to make operations call for AWS Performance Insights.

func New 

func New(options Options, optFns ...func(*Options)) *Client

New returns an initialized Client based on the functional options. Provide additional functional options to further configure the behavior of the client, such as changing the client's endpoint or adding custom middleware behavior.

func NewFromConfig 

func NewFromConfig(cfg aws.Config, optFns ...func(*Options)) *Client

NewFromConfig returns a new client from the provided config.

func (*Client) DescribeDimensionKeys 

func (c *Client) DescribeDimensionKeys(ctx context.Context, params *DescribeDimensionKeysInput, optFns ...func(*Options)) (*DescribeDimensionKeysOutput, error)

For a specific time period, retrieve the top N dimension keys for a metric. Each response element returns a maximum of 500 bytes. For larger elements, such as SQL statements, only the first 500 bytes are returned.

func (*Client) GetResourceMetrics 

func (c *Client) GetResourceMetrics(ctx context.Context, params *GetResourceMetricsInput, optFns ...func(*Options)) (*GetResourceMetricsOutput, error)

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.

type DescribeDimensionKeysInput 

type DescribeDimensionKeysInput struct {

	// The date and time specifying the end of the requested time series data. The
	// value specified is exclusive, which means that data points less than (but not
	// equal to) EndTime are returned. The value for EndTime must be later than the
	// value for StartTime.
	//
	// This member is required.
	EndTime *time.Time

	// A specification for how to aggregate the data points from a query result. You
	// must specify a valid dimension group. Performance Insights returns all
	// dimensions within this group, unless you provide the names of specific
	// dimensions within this group. You can also request that Performance Insights
	// return a limited number of values for a dimension.
	//
	// This member is required.
	GroupBy *types.DimensionGroup

	// An immutable, AWS Region-unique identifier for a data source. Performance
	// Insights gathers metrics from this data source. To use an Amazon RDS instance as
	// a data source, you specify its DbiResourceId value. For example, specify
	// db-FAIHNTYBKTGAUSUZQYPDS2GW4A
	//
	// This member is required.
	Identifier *string

	// The name of a Performance Insights metric to be measured. Valid values for
	// Metric are:

	// * db.load.avg - a scaled representation of the number of active
	// sessions for the database engine.
	//
	// * db.sampledload.avg - the raw number of
	// active sessions for the database engine.
	//
	// If the number of active sessions is
	// less than an internal Performance Insights threshold, db.load.avg and
	// db.sampledload.avg are the same value. If the number of active sessions is
	// greater than the internal threshold, Performance Insights samples the active
	// sessions, with db.load.avg showing the scaled values, db.sampledload.avg showing
	// the raw values, and db.sampledload.avg less than db.load.avg. For most use
	// cases, you can query db.load.avg only.
	//
	// This member is required.

	// valid value for ServiceType is RDS.

	StartTime *time.Time

	// One or more filters to apply in the request. Restrictions:

	NextToken *string

	// For each dimension specified in GroupBy, specify a secondary dimension to
	// further subdivide the partition keys in the response.
	PartitionBy *types.DimensionGroup

	// 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
