Description

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

Use Amazon CloudWatch Observability Access Manager to create and manage links between source accounts and monitoring accounts by using CloudWatch cross-account observability. With CloudWatch cross-account observability, you can monitor and troubleshoot applications that span multiple accounts within a Region. Seamlessly search, visualize, and analyze your metrics, logs, traces, Application Signals services and service level objectives (SLOs), Application Insights applications, and internet monitors in any of the linked accounts without account boundaries.

Set up one or more Amazon Web Services accounts as monitoring accounts and link them with multiple source accounts. A monitoring account is a central Amazon Web Services account that can view and interact with observability data generated from source accounts. A source account is an individual Amazon Web Services account that generates observability data for the resources that reside in it. Source accounts share their observability data with the monitoring account. The shared observability data can include metrics in Amazon CloudWatch, logs in Amazon CloudWatch Logs, traces in X-Ray, Application Signals services and service level objectives (SLOs), applications in Amazon CloudWatch Application Insights, and internet monitors in CloudWatch Internet Monitor.

When you set up a link, you can choose to share the metrics from all namespaces with the monitoring account, or filter to a subset of namespaces. And for CloudWatch Logs, you can choose to share all log groups with the monitoring account, or filter to a subset of log groups.

Installing

To install this package, simply type add or install @aws-sdk/client-oam using your favorite package manager:

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

Getting Started

Import

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

// ES5 example
const { OAMClient, ListLinksCommand } = require("@aws-sdk/client-oam");

// ES6+ example
import { OAMClient, ListLinksCommand } from "@aws-sdk/client-oam";

Usage

To send a request, you:

• Initiate client with configuration (e.g. credentials, region).
• Initiate command with input parameters.
• Call send operation on client with command object as input.
• If you are using a custom http handler, you may call destroy() to close open connections.

// a client can be shared by different commands.
const client = new OAMClient({ region: "REGION" });

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

Async/await

We recommend using 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.
}

Async-await is clean, concise, intuitive, easy to debug and has better error handling as compared to using Promise chains or callbacks.

Promises

You can also use Promise chaining to execute send operation.

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

Promises can also be called using .catch() and .finally() as follows:

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

Callbacks

We do not recommend using callbacks because of callback hell, but they are supported by the send operation.

// callbacks.
client.send(command, (err, data) => {
  // process err and data.
});

v2 compatible style

The client can also send requests using v2 compatible style. However, it results in a bigger bundle size and may be dropped in next major version. More details in the blog post on modular packages in AWS SDK for JavaScript

import * as AWS from "@aws-sdk/client-oam";
const client = new AWS.OAM({ region: "REGION" });

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

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

// callbacks.
client.listLinks(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;
   * }
   */
}
