# Bekerja dengan CloudWatch Alarm
<a name="examples-cloudwatch-create-alarms"></a>

## Buat Alarm
<a name="create-an-alarm"></a>

Untuk membuat alarm berdasarkan CloudWatch metrik, panggil `putMetricAlarm` metode dengan [PutMetricAlarmRequest](https://docs.aws.amazon.com/sdk-for-java/v1/reference/com/amazonaws/services/cloudwatch/model/PutMetricAlarmRequest.html)diisi dengan kondisi alarm. AmazonCloudWatchClient

 **Impor** 

```
import com.amazonaws.services.cloudwatch.AmazonCloudWatch;
import com.amazonaws.services.cloudwatch.AmazonCloudWatchClientBuilder;
import com.amazonaws.services.cloudwatch.model.ComparisonOperator;
import com.amazonaws.services.cloudwatch.model.Dimension;
import com.amazonaws.services.cloudwatch.model.PutMetricAlarmRequest;
import com.amazonaws.services.cloudwatch.model.PutMetricAlarmResult;
import com.amazonaws.services.cloudwatch.model.StandardUnit;
import com.amazonaws.services.cloudwatch.model.Statistic;
```

 **Kode** 

```
final AmazonCloudWatch cw =
    AmazonCloudWatchClientBuilder.defaultClient();

Dimension dimension = new Dimension()
    .withName("InstanceId")
    .withValue(instanceId);

PutMetricAlarmRequest request = new PutMetricAlarmRequest()
    .withAlarmName(alarmName)
    .withComparisonOperator(
        ComparisonOperator.GreaterThanThreshold)
    .withEvaluationPeriods(1)
    .withMetricName("CPUUtilization")
    .withNamespace("{AWS}/EC2")
    .withPeriod(60)
    .withStatistic(Statistic.Average)
    .withThreshold(70.0)
    .withActionsEnabled(false)
    .withAlarmDescription(
        "Alarm when server CPU utilization exceeds 70%")
    .withUnit(StandardUnit.Seconds)
    .withDimensions(dimension);

PutMetricAlarmResult response = cw.putMetricAlarm(request);
```

## Daftar Alarm
<a name="list-alarms"></a>

Untuk membuat daftar CloudWatch alarm yang telah Anda buat, panggil `describeAlarms` metode ini dengan [DescribeAlarmsRequest](https://docs.aws.amazon.com/sdk-for-java/v1/reference/com/amazonaws/services/cloudwatch/model/DescribeAlarmsRequest.html)yang dapat Anda gunakan untuk mengatur opsi untuk hasilnya. AmazonCloudWatchClient

 **Impor** 

```
import com.amazonaws.services.cloudwatch.AmazonCloudWatch;
import com.amazonaws.services.cloudwatch.AmazonCloudWatchClientBuilder;
import com.amazonaws.services.cloudwatch.model.DescribeAlarmsRequest;
import com.amazonaws.services.cloudwatch.model.DescribeAlarmsResult;
import com.amazonaws.services.cloudwatch.model.MetricAlarm;
```

 **Kode** 

```
final AmazonCloudWatch cw =
    AmazonCloudWatchClientBuilder.defaultClient();

boolean done = false;
DescribeAlarmsRequest request = new DescribeAlarmsRequest();

while(!done) {

    DescribeAlarmsResult response = cw.describeAlarms(request);

    for(MetricAlarm alarm : response.getMetricAlarms()) {
        System.out.printf("Retrieved alarm %s", alarm.getAlarmName());
    }

    request.setNextToken(response.getNextToken());

    if(response.getNextToken() == null) {
        done = true;
    }
}
```

Daftar alarm dapat diperoleh dengan memanggil `getMetricAlarms` [DescribeAlarmsResult](https://docs.aws.amazon.com/sdk-for-java/v1/reference/com/amazonaws/services/cloudwatch/model/DescribeAlarmsResult.html)yang dikembalikan oleh`describeAlarms`.

Hasilnya mungkin *paged.* Untuk mengambil batch hasil berikutnya, panggil `setNextToken` objek permintaan asli dengan nilai kembali dari `getNextToken` metode `DescribeAlarmsResult` objek, dan meneruskan objek permintaan yang dimodifikasi kembali ke `describeAlarms` panggilan lain.

**catatan**  
Anda juga dapat mengambil alarm untuk metrik tertentu dengan menggunakan metode ini AmazonCloudWatchClient. `describeAlarmsForMetric` Penggunaannya mirip dengan`describeAlarms`.

## Hapus Alarm
<a name="delete-alarms"></a>

Untuk menghapus CloudWatch alarm, panggil `deleteAlarms` metode ini dengan [DeleteAlarmsRequest](https://docs.aws.amazon.com/sdk-for-java/v1/reference/com/amazonaws/services/cloudwatch/model/DeleteAlarmsRequest.html)berisi satu atau beberapa nama alarm yang ingin Anda hapus. AmazonCloudWatchClient

 **Impor** 

```
import com.amazonaws.services.cloudwatch.AmazonCloudWatch;
import com.amazonaws.services.cloudwatch.AmazonCloudWatchClientBuilder;
import com.amazonaws.services.cloudwatch.model.DeleteAlarmsRequest;
import com.amazonaws.services.cloudwatch.model.DeleteAlarmsResult;
```

 **Kode** 

```
final AmazonCloudWatch cw =
    AmazonCloudWatchClientBuilder.defaultClient();

DeleteAlarmsRequest request = new DeleteAlarmsRequest()
    .withAlarmNames(alarm_name);

DeleteAlarmsResult response = cw.deleteAlarms(request);
```
