# Gunakan CloudWatch Acara Amazon
CloudWatch Acara memberikan aliran peristiwa sistem yang mendekati real-time yang menggambarkan perubahan AWS sumber daya ke Amazon EC2 instance, Lambda fungsi, Kinesis aliran, Amazon ECS tugas, mesin Step Functions status, Amazon SNS topik, Amazon SQS antrian, atau target bawaan. Anda dapat mencocokkan acara dan meruteknya ke satu atau beberapa fungsi atau aliran target dengan menggunakan aturan sederhana.
Amazon EventBridge adalah [evolusi](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-cwe-now-eb.html) dari CloudWatch Peristiwa. Kedua layanan menggunakan API yang sama, sehingga Anda dapat terus menggunakan [klien CloudWatch Acara](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/cloudwatch/CloudWatchClient.html) yang disediakan oleh SDK atau bermigrasi ke fungsionalitas SDK untuk [EventBridge klien](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/eventbridge/EventBridgeClient.html) Java untuk CloudWatch Acara. CloudWatch [Dokumentasi Panduan Pengguna](https://docs.aws.amazon.com/eventbridge/latest/userguide/index.html) Acara dan [referensi API](https://docs.aws.amazon.com/eventbridge/latest/APIReference/index.html) sekarang tersedia melalui situs EventBridge dokumentasi.
## Tambahkan acara
Untuk menambahkan CloudWatch peristiwa khusus, panggil `CloudWatchEventsClient’s` `putEvents` metode dengan [https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/cloudwatchevents/model/PutEventsRequest.html](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/cloudwatchevents/model/PutEventsRequest.html)objek yang berisi satu atau beberapa [https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/cloudwatchevents/model/PutEventsRequestEntry.html](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/cloudwatchevents/model/PutEventsRequestEntry.html)objek yang memberikan detail tentang setiap peristiwa. Anda dapat menentukan beberapa parameter untuk entri seperti sumber dan jenis acara, sumber daya yang terkait dengan acara, dan sebagainya.
**catatan**
Anda dapat menentukan maksimum 10 acara per panggilan ke`putEvents`.

**Kode**

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);
}
}

## Tambahkan aturan
Untuk membuat atau memperbarui aturan, panggil `CloudWatchEventsClient’s` `putRule` metode [https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/cloudwatchevents/model/PutRuleRequest.html](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/cloudwatchevents/model/PutRuleRequest.html)dengan nama aturan dan parameter opsional seperti [pola acara](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-event-patterns.html), IAM peran untuk dikaitkan dengan aturan, dan [ekspresi penjadwalan](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-create-rule-schedule.html) yang menjelaskan seberapa sering aturan dijalankan.

import software.amazon.awssdk.services.cloudwatchevents.model.PutRuleResponse;
import software.amazon.awssdk.services.cloudwatchevents.model.RuleState;

public static void putCWRule(CloudWatchEventsClient cwe, String ruleName, String roleArn) {
try {
PutRuleRequest request = PutRuleRequest.builder()
.name(ruleName)
.roleArn(roleArn)
.scheduleExpression("rate(5 minutes)")
.state(RuleState.ENABLED)
.build();
PutRuleResponse response = cwe.putRule(request);
System.out.printf(
"Successfully created CloudWatch events rule %s with arn %s",
roleArn, response.ruleArn());
} catch (
CloudWatchException e) {
System.err.println(e.awsErrorDetails().errorMessage());
System.exit(1);
}
}

## Menambahkan target
Target adalah sumber daya yang dipanggil ketika suatu aturan dipicu. Contoh target termasuk Amazon EC2 instance, Lambda fungsi, Kinesis aliran, Amazon ECS tugas, mesin Step Functions status, dan target bawaan.
Untuk menambahkan target ke aturan, panggil `CloudWatchEventsClient’s` `putTargets` metode dengan [https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/cloudwatchevents/model/PutTargetsRequest.html](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/cloudwatchevents/model/PutTargetsRequest.html)berisi aturan untuk diperbarui dan daftar target untuk ditambahkan ke aturan.

Target target = Target.builder()
.arn(functionArn)
.id(targetId)
.build();
PutTargetsRequest request = PutTargetsRequest.builder()
.targets(target)
.rule(ruleName)
.build();
PutTargetsResponse response = cwe.putTargets(request);
System.out.printf(
"Successfully created CloudWatch events target for rule %s",
ruleName);
} catch (CloudWatchException e) {
System.err.println(e.awsErrorDetails().errorMessage());
System.exit(1);
}
}
