Send CloudWatch Events events using an Amazon SDK

The following code examples show how to send Amazon CloudWatch Events events.

Java
SDK for Java 2.x

There's more on GitHub. Find the complete example and learn how to set up and run in the Amazon Code Examples Repository.

public static void putCWEvents(CloudWatchEventsClient cwe, String resourceArn ) { try { final String EVENT_DETAILS = "{ \"key1\": \"value1\", \"key2\": \"value2\" }"; PutEventsRequestEntry requestEntry = PutEventsRequestEntry.builder() .detail(EVENT_DETAILS) .detailType("sampleSubmitted") .resources(resourceArn) .source("aws-sdk-java-cloudwatch-example") .build(); PutEventsRequest request = PutEventsRequest.builder() .entries(requestEntry) .build(); cwe.putEvents(request); System.out.println("Successfully put CloudWatch event"); } catch (CloudWatchException e) { System.err.println(e.awsErrorDetails().errorMessage()); System.exit(1); } }

JavaScript
SDK for JavaScript V3
Note

Create the client in a separate module and export it.

import { CloudWatchEventsClient } from "@aws-sdk/client-cloudwatch-events"; import { DEFAULT_REGION } from "libs/utils/util-aws-sdk.js"; export const client = new CloudWatchEventsClient({ region: DEFAULT_REGION });

Import the SDK and client modules and call the API.

import { PutEventsCommand } from "@aws-sdk/client-cloudwatch-events"; import { client } from "../libs/client.js"; const run = async () => { const command = new PutEventsCommand({ // The list of events to send to Amazon CloudWatch Events. Entries: [ { // The name of the application or service that is sending the event. Source: "my.app", // The name of the event that is being sent. DetailType: "My Custom Event", // The data that is sent with the event. Detail: JSON.stringify({ timeOfEvent: new Date().toISOString() }), }, ], }); try { return await client.send(command); } catch (err) { console.error(err); } }; export default run();
SDK for JavaScript V2
Note

// Load the AWS SDK for Node.js var AWS = require('aws-sdk'); // Set the region AWS.config.update({region: 'REGION'}); // Create CloudWatchEvents service object var cwevents = new AWS.CloudWatchEvents({apiVersion: '2015-10-07'}); var params = { Entries: [ { Detail: '{ \"key1\": \"value1\", \"key2\": \"value2\" }', DetailType: 'appRequestSubmitted', Resources: [ 'RESOURCE_ARN', ], Source: 'com.company.app' } ] }; cwevents.putEvents(params, function(err, data) { if (err) { console.log("Error", err); } else { console.log("Success", data.Entries); } });
