Description

AWS SDK for JavaScript PI Client for Node.js, Browser and React Native.

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 Amazon Web Services 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.

Installing

To install this package, use the CLI of your favorite package manager:

• npm install @aws-sdk/client-pi
• yarn add @aws-sdk/client-pi
• pnpm add @aws-sdk/client-pi

Getting Started

Import

The AWS SDK is modulized by clients and commands. To send a request, you only need to import the PIClient and the commands you need, for example ListTagsForResourceCommand:

// ES5 example
const { PIClient, ListTagsForResourceCommand } = require("@aws-sdk/client-pi");

// ES6+ example
import { PIClient, ListTagsForResourceCommand } from "@aws-sdk/client-pi";

Usage

To send a request:

• Instantiate a client with configuration (e.g. credentials, region).
  • See docs/CLIENTS for configuration details.
  • See @aws-sdk/config for additional options.
• Instantiate a command with input parameters.
• Call the send operation on the client, providing the command object as input.

const client = new PIClient({ region: "REGION" });

const params = { /** input parameters */ };
const command = new ListTagsForResourceCommand(params);

Supported Message Protocols

This client supports multiple protocols.

The default for this client is AWS JSON (RPC) 1.1.

We have selected this default based on our evaluation of the performance characteristics of this protocol format in JavaScript. You don't need to change it, but you have the option to do so, for example to support existing integrations or tests. Selecting a non-default protocol changes the format of the data sent over the network, but does not affect how you interact with the client using JavaScript objects.

Install the @aws-sdk/config package to access alternate protocols.

See AWS Protocols for more information.

AWS JSON (RPC) 1.1

This protocol uses JSON payloads.

import { AwsJson1_1Protocol } from "@aws-sdk/config/protocol";

const client = new PIClient({
  protocol: AwsJson1_1Protocol
});

Smithy RPC v2 CBOR

This protocol uses CBOR payloads.

import { AwsSmithyRpcV2CborProtocol } from "@aws-sdk/config/protocol";

const client = new PIClient({
  protocol: AwsSmithyRpcV2CborProtocol
});

Async/await

We recommend using the await operator to wait for the promise returned by send operation as follows:

// async/await.
try {
  const data = await client.send(command);
  // process data.
} catch (error) {
  // error handling.
} finally {
  // finally.
}

Promises

You can also use Promise chaining.

client
  .send(command)
  .then((data) => {
    // process data.
  })
  .catch((error) => {
    // error handling.
  })
  .finally(() => {
    // finally.
  });

Aggregated client

The aggregated client class is exported from the same package, but without the "Client" suffix.

PI extends PIClient and additionally supports all operations, waiters, and paginators as methods. This style may be familiar to you from the AWS SDK for JavaScript v2.

If you are bundling the AWS SDK, we recommend using only the bare-bones client (PIClient). More details are in the blog post on modular packages in AWS SDK for JavaScript.

import { PI } from "@aws-sdk/client-pi";

const client = new PI({ region: "REGION" });

// async/await.
try {
  const data = await client.listTagsForResource(params);
  // process data.
} catch (error) {
  // error handling.
}

// Promises.
client
  .listTagsForResource(params)
  .then((data) => {
    // process data.
  })
  .catch((error) => {
    // error handling.
  });

// callbacks (not recommended).
client.listTagsForResource(params, (err, data) => {
  // process err and data.
});

Troubleshooting

When the service returns an exception, the error will include the exception information, as well as response metadata (e.g. request id).

try {
  const data = await client.send(command);
  // process data.
} catch (error) {
  const { requestId, cfId, extendedRequestId } = error.$metadata;
  console.log({ requestId, cfId, extendedRequestId });
  /**
   * The keys within exceptions are also parsed.
   * You can access them by specifying exception names:
   * if (error.name === 'SomeServiceException') {
   *     const value = error.specialKeyInException;
   * }
   */
}
