AWS SDK for JavaScript InternetMonitor Client for Node.js, Browser and React Native.
Amazon CloudWatch Internet Monitor provides visibility into how internet issues impact the performance and availability between your applications hosted on Amazon Web Services and your end users. It can reduce the time it takes for you to diagnose internet issues from days to minutes. Internet Monitor uses the connectivity data that Amazon Web Services captures from its global networking footprint to calculate a baseline of performance and availability for internet traffic. This is the same data that Amazon Web Services uses to monitor internet uptime and availability. With those measurements as a baseline, Internet Monitor raises awareness for you when there are significant problems for your end users in the different geographic locations where your application runs.
Internet Monitor publishes internet measurements to CloudWatch Logs and CloudWatch Metrics, to easily support using CloudWatch tools with health information for geographies and networks specific to your application. Internet Monitor sends health events to Amazon EventBridge so that you can set up notifications. If an issue is caused by the Amazon Web Services network, you also automatically receive an Amazon Web Services Health Dashboard notification with the steps that Amazon Web Services is taking to mitigate the problem.
To use Internet Monitor, you create a monitor and associate your application's resources with it - VPCs, NLBs, CloudFront distributions, or WorkSpaces directories - so Internet Monitor can determine where your application's internet traffic is. Internet Monitor then provides internet measurements from Amazon Web Services that are specific to the locations and ASNs (typically, internet service providers or ISPs) that communicate with your application.

To install the this package, simply type add or install @aws-sdk/client-internetmonitor using your favorite package manager:
npm install @aws-sdk/client-internetmonitoryarn add @aws-sdk/client-internetmonitorpnpm add @aws-sdk/client-internetmonitor
The AWS SDK is modulized by clients and commands.
To send a request, you only need to import the InternetMonitorClient and
the commands you need, for example ListMonitorsCommand:
// ES5 example
const { InternetMonitorClient, ListMonitorsCommand } = require("@aws-sdk/client-internetmonitor");// ES6+ example
import { InternetMonitorClient, ListMonitorsCommand } from "@aws-sdk/client-internetmonitor";To send a request, you:
- Initiate client with configuration (e.g. credentials, region).
- Initiate command with input parameters.
- Call
sendoperation 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 InternetMonitorClient({ region: "REGION" });
const params = {
/** input parameters */
};
const command = new ListMonitorsCommand(params);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.
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.
});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.
});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-internetmonitor";
const client = new AWS.InternetMonitor({ region: "REGION" });
// async/await.
try {
const data = await client.listMonitors(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.listMonitors(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.listMonitors(params, (err, data) => {
// process err and data.
});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;
* }
