# Menggunakan Tindakan Alarm di CloudWatch
<a name="examples-cloudwatch-use-alarm-actions"></a>

Dengan menggunakan tindakan CloudWatch alarm, Anda dapat membuat alarm yang melakukan tindakan seperti menghentikan, menghentikan, me-reboot, atau memulihkan instans Amazon EC2 secara otomatis.

Tindakan alarm dapat ditambahkan ke alarm dengan menggunakan `SetAlarmActions` fungsi saat [membuat alarm](examples-cloudwatch-create-alarms.md). [PutMetricAlarmRequest](https://docs.aws.amazon.com/sdk-for-cpp/latest/api/aws-cpp-sdk-monitoring/html/class_aws_1_1_cloud_watch_1_1_model_1_1_put_metric_alarm_request.html)

## Prasyarat
<a name="codeExamplePrereq"></a>

Sebelum Anda mulai, kami sarankan Anda membaca [Memulai menggunakan AWS SDK untuk C\+\+](getting-started.md). 

Unduh kode contoh dan buat solusinya seperti yang dijelaskan dalam[Memulai contoh kode](getting-started-code-examples.md). 

Untuk menjalankan contoh, profil pengguna yang digunakan kode Anda untuk membuat permintaan harus memiliki izin yang tepat AWS (untuk layanan dan tindakan). Untuk informasi selengkapnya, lihat [Menyediakan AWS kredensi](credentials.md).

## Aktifkan Tindakan Alarm
<a name="enable-alarm-actions"></a>

Untuk mengaktifkan tindakan alarm untuk CloudWatch alarm, panggil CloudWatchClient's `EnableAlarmActions` dengan [EnableAlarmActionsRequest](https://docs.aws.amazon.com/sdk-for-cpp/latest/api/aws-cpp-sdk-monitoring/html/class_aws_1_1_cloud_watch_1_1_model_1_1_enable_alarm_actions_request.html)berisi satu atau beberapa nama alarm yang tindakannya ingin Anda aktifkan.

 **Termasuk** 

```
#include <aws/core/Aws.h>
#include <aws/monitoring/CloudWatchClient.h>
#include <aws/monitoring/model/EnableAlarmActionsRequest.h>
#include <aws/monitoring/model/PutMetricAlarmRequest.h>
#include <iostream>
```

 **Kode** 

```
    Aws::CloudWatch::CloudWatchClient cw;
    Aws::CloudWatch::Model::PutMetricAlarmRequest request;
    request.SetAlarmName(alarm_name);
    request.SetComparisonOperator(
        Aws::CloudWatch::Model::ComparisonOperator::GreaterThanThreshold);
    request.SetEvaluationPeriods(1);
    request.SetMetricName("CPUUtilization");
    request.SetNamespace("AWS/EC2");
    request.SetPeriod(60);
    request.SetStatistic(Aws::CloudWatch::Model::Statistic::Average);
    request.SetThreshold(70.0);
    request.SetActionsEnabled(false);
    request.SetAlarmDescription("Alarm when server CPU exceeds 70%");
    request.SetUnit(Aws::CloudWatch::Model::StandardUnit::Seconds);
    request.AddAlarmActions(actionArn);

    Aws::CloudWatch::Model::Dimension dimension;
    dimension.SetName("InstanceId");
    dimension.SetValue(instanceId);
    request.AddDimensions(dimension);

    auto outcome = cw.PutMetricAlarm(request);
    if (!outcome.IsSuccess())
    {
        std::cout << "Failed to create CloudWatch alarm:" <<
            outcome.GetError().GetMessage() << std::endl;
        return;
    }

    Aws::CloudWatch::Model::EnableAlarmActionsRequest enable_request;
    enable_request.AddAlarmNames(alarm_name);

    auto enable_outcome = cw.EnableAlarmActions(enable_request);
    if (!enable_outcome.IsSuccess())
    {
        std::cout << "Failed to enable alarm actions:" <<
            enable_outcome.GetError().GetMessage() << std::endl;
        return;
    }

    std::cout << "Successfully created alarm " << alarm_name <<
        " and enabled actions on it." << std::endl;
```

## Nonaktifkan Tindakan Alarm
<a name="disable-alarm-actions"></a>

Untuk menonaktifkan tindakan alarm untuk CloudWatch alarm, hubungi CloudWatchClient's `DisableAlarmActions` dengan [DisableAlarmActionsRequest](https://docs.aws.amazon.com/sdk-for-cpp/latest/api/aws-cpp-sdk-monitoring/html/class_aws_1_1_cloud_watch_1_1_model_1_1_disable_alarm_actions_request.html)berisi satu atau beberapa nama alarm yang tindakannya ingin Anda nonaktifkan.

 **Termasuk** 

```
#include <aws/core/Aws.h>
#include <aws/monitoring/CloudWatchClient.h>
#include <aws/monitoring/model/DisableAlarmActionsRequest.h>
#include <iostream>
```

 **Kode** 

```
        Aws::CloudWatch::CloudWatchClient cw;

        Aws::CloudWatch::Model::DisableAlarmActionsRequest disableAlarmActionsRequest;
        disableAlarmActionsRequest.AddAlarmNames(alarm_name);

        auto disableAlarmActionsOutcome = cw.DisableAlarmActions(disableAlarmActionsRequest);
        if (!disableAlarmActionsOutcome.IsSuccess())
        {
            std::cout << "Failed to disable actions for alarm " << alarm_name <<
                ": " << disableAlarmActionsOutcome.GetError().GetMessage() <<
                std::endl;
        }
        else
        {
            std::cout << "Successfully disabled actions for alarm " <<
                alarm_name << std::endl;
        }
```
