# CloudWatch Contoh Amazon menggunakan AWS SDK untuk PHP Versi 3
<a name="cw-examples"></a>

Amazon CloudWatch (CloudWatch) adalah layanan web yang memantau sumber daya Amazon Web Services Anda dan aplikasi yang Anda jalankan AWS secara real time. Anda dapat menggunakan CloudWatch untuk mengumpulkan dan melacak metrik, yang merupakan variabel yang dapat Anda ukur untuk sumber daya dan aplikasi Anda. CloudWatch alarm mengirim pemberitahuan atau secara otomatis membuat perubahan pada sumber daya yang Anda pantau berdasarkan aturan yang Anda tetapkan.

Semua kode contoh untuk AWS SDK untuk PHP tersedia [di sini GitHub](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/php/example_code).

## Kredensial
<a name="examplecredentials"></a>

Sebelum menjalankan kode contoh, konfigurasikan AWS kredenal Anda, seperti yang dijelaskan dalam. [Mengautentikasi dengan AWS menggunakan AWS SDK untuk PHP Versi 3](credentials.md) Kemudian impor AWS SDK untuk PHP, seperti yang dijelaskan dalam[Menginstal AWS SDK untuk PHP Versi 3](getting-started_installation.md).

# Bekerja dengan CloudWatch alarm Amazon dengan AWS SDK untuk PHP Versi 3
<a name="cw-examples-work-with-alarms"></a>

 CloudWatch Alarm Amazon menonton satu metrik selama periode waktu yang Anda tentukan. Alarm tersebut melakukan satu atau beberapa tindakan berdasarkan nilai metrik yang relatif terhadap ambang batas tertentu selama beberapa periode waktu.

Contoh berikut menunjukkan cara:
+ Jelaskan alarm menggunakan [DescribeAlarms](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-monitoring-2010-08-01.html#describealarms).
+ Buat alarm menggunakan [PutMetricAlarm](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-monitoring-2010-08-01.html#putmetricalarm).
+ Hapus alarm menggunakan [DeleteAlarms](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-monitoring-2010-08-01.html#deletealarms).

Metrik adalah data tentang performa sistem Anda. Alarm mengawasi satu metrik selama suatu periode waktu yang Anda tentukan. Ini melakukan satu atau lebih tindakan berdasarkan nilai metrik, relatif terhadap ambang batas yang diberikan selama sejumlah periode waktu.

Contoh berikut menunjukkan cara:
+ Publikasikan data metrik menggunakan [PutMetricData](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-monitoring-2010-08-01.html#putmetricdata).
+ Buat alarm menggunakan [PutMetricAlarm](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-monitoring-2010-08-01.html#putmetricalarm).

Semua kode contoh untuk AWS SDK untuk PHP tersedia [di sini GitHub](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/php/example_code).

Sebelum menjalankan kode contoh, konfigurasikan AWS kredenal Anda, seperti yang dijelaskan dalam.

# Mengirim acara ke CloudWatch Acara Amazon dengan AWS SDK untuk PHP Versi 3
<a name="cw-examples-sending-events"></a>

CloudWatch Acara memberikan aliran peristiwa sistem yang mendekati real-time yang menjelaskan perubahan sumber daya Amazon Web Services (AWS) ke salah satu dari berbagai target. Dengan menggunakan aturan sederhana, Anda dapat mencocokkan acara dan meruteknya ke satu atau beberapa fungsi atau aliran target.

Contoh berikut menunjukkan cara:
+ Buat aturan menggunakan [PutRule](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-events-2015-10-07.html#putrule).
+ Tambahkan target ke aturan menggunakan [PutTargets](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-events-2015-10-07.html#puttargets).
+ Kirim acara khusus ke CloudWatch Acara menggunakan [PutEvents](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-events-2015-10-07.html#putevents).

# Menggunakan tindakan alarm dengan CloudWatch alarm Amazon dengan AWS SDK untuk PHP Versi 3
<a name="cw-examples-using-alarm-actions"></a>

Gunakan tindakan alarm untuk membuat alarm yang secara otomatis menghentikan, menghentikan, reboot, atau memulihkan instans Amazon EC2 Anda. Anda dapat menggunakan tindakan berhenti atau menghentikan saat Anda tidak lagi membutuhkan instance untuk dijalankan. Anda dapat menggunakan tindakan reboot dan memulihkan untuk secara otomatis me-reboot instance tersebut.

Contoh berikut menunjukkan cara:
+ Aktifkan tindakan untuk alarm tertentu menggunakan [EnableAlarmActions](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-monitoring-2010-08-01.html#enablealarmactions).
+ Nonaktifkan tindakan untuk alarm tertentu menggunakan [DisableAlarmActions](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-monitoring-2010-08-01.html#disablealarmactions).
