Overview

Package pi provides the client and types for making API requests to AWS PI.

AWS Performance Insights enables you to monitor and explore different dimensions of database load based on data captured from a running RDS instance. The guide provides detailed information about Performance Insights data types, parameters and errors. For more information about Performance Insights capabilities see Using Amazon RDS Performance Insights (http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_PerfInsights.html) in the Amazon RDS User Guide.

The AWS Performance Insights API provides visibility into the performance of your RDS instance, when Performance Insights is enabled for supported engine types. While Amazon CloudWatch provides the authoritative source for AWS service vended monitoring metrics, AWS Performance Insights offers a domain-specific view of database load measured as Average Active Sessions and provided to API consumers as a 2-dimensional time-series dataset. The time dimension of the data provides DB load data for each time point in the queried time range, and each time point decomposes overall load in relation to the requested dimensions, such as SQL, Wait-event, User or Host, measured at that time point.

See https://docs.aws.amazon.com/goto/WebAPI/pi-2018-02-27 for more information on this service.

See pi package documentation for more information. https://docs.aws.amazon.com/sdk-for-go/api/service/pi/

Using the Client

To use AWS PI with the SDK use the New function to create a new service client. With that client you can make API requests to the service. These clients are safe to use concurrently.

See the SDK's documentation for more information on how to use the SDK. https://docs.aws.amazon.com/sdk-for-go/api/

See aws.Config documentation for more information on configuring SDK clients. https://docs.aws.amazon.com/sdk-for-go/api/aws/#Config

See the AWS PI client for more information on creating client for this service. https://docs.aws.amazon.com/sdk-for-go/api/service/pi/#New

Types

type Client added in v0.9.0 

type Client struct {
	*aws.Client
}

Client provides the API operation methods for making requests to AWS PI. See this package's package overview docs for details on the service.

The client's methods are safe to use concurrently. It is not safe to modify mutate any of the struct's properties though.

func New 

func New(config aws.Config) *Client

New creates a new instance of the client from the provided Config.

Example: 

// Create a client from just a config.
svc := pi.New(myConfig)

func (*Client) DescribeDimensionKeysRequest added in v0.9.0 

func (c *Client) DescribeDimensionKeysRequest(input *DescribeDimensionKeysInput) DescribeDimensionKeysRequest

DescribeDimensionKeysRequest returns a request value for making API operation for AWS Performance Insights.

For a specific time period, retrieve the top N dimension keys for a metric. 

// Example sending a request using DescribeDimensionKeysRequest.
req := client.DescribeDimensionKeysRequest(params)
resp, err := req.Send(context.TODO())
if err == nil {
    fmt.Println(resp)
