# Mengelola Instans Amazon EC2
<a name="examples-ec2-instances"></a>

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

Sebelum Anda mulai, kami sarankan Anda membaca [Memulai menggunakan AWS SDK untuk C\$1\$1](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).

## Buat sebuah Instance
<a name="create-an-instance"></a>

Buat instans Amazon EC2 baru dengan memanggil `RunInstances` fungsi EC2 Klien, menyediakannya [RunInstancesRequest](https://docs.aws.amazon.com/sdk-for-cpp/latest/api/aws-cpp-sdk-ec2/html/class_aws_1_1_e_c2_1_1_model_1_1_run_instances_request.html)berisi [Amazon Machine Image (AMI)](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AMIs.html) untuk digunakan dan jenis [instans](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html).

 **Termasuk** 

```
#include <aws/core/Aws.h>
#include <aws/ec2/EC2Client.h>
#include <aws/ec2/model/RunInstancesRequest.h>
#include <iostream>

    Aws::EC2::Model::RunInstancesRequest runRequest;
    runRequest.SetImageId(amiId);
    runRequest.SetInstanceType(Aws::EC2::Model::InstanceType::t1_micro);
    runRequest.SetMinCount(1);
    runRequest.SetMaxCount(1);

    Aws::EC2::Model::RunInstancesOutcome runOutcome = ec2Client.RunInstances(
            runRequest);
    if (!runOutcome.IsSuccess()) {
        std::cerr << "Failed to launch EC2 instance " << instanceName <<
                  " based on ami " << amiId << ":" <<
                  runOutcome.GetError().GetMessage() << std::endl;
        return false;
    }

    const Aws::Vector<Aws::EC2::Model::Instance> &instances = runOutcome.GetResult().GetInstances();
    if (instances.empty()) {
        std::cerr << "Failed to launch EC2 instance " << instanceName <<
                  " based on ami " << amiId << ":" <<

## Jelaskan Contoh
<a name="describe-instances"></a>

Untuk membuat daftar instance Anda, buat [DescribeInstancesRequest](https://docs.aws.amazon.com/sdk-for-cpp/latest/api/aws-cpp-sdk-ec2/html/class_aws_1_1_e_c2_1_1_model_1_1_describe_instances_request.html)dan panggil `DescribeInstances` fungsi EC2 Klien. Ini akan mengembalikan [DescribeInstancesResponse](https://docs.aws.amazon.com/sdk-for-cpp/latest/api/aws-cpp-sdk-ec2/html/class_aws_1_1_e_c2_1_1_model_1_1_describe_instances_response.html)objek yang dapat Anda gunakan untuk membuat daftar instans Amazon EC2 untuk Anda dan. Akun AWS Wilayah AWS

*Instans dikelompokkan berdasarkan reservasi.* Setiap reservasi sesuai dengan panggilan `StartInstances` yang meluncurkan instance. Untuk membuat daftar instance Anda, Anda harus terlebih dahulu memanggil `GetReservations` fungsi `DescribeInstancesResponse` kelas, dan kemudian memanggil `getInstances` setiap objek Reservasi yang dikembalikan.

 **Termasuk** 

```
#include <aws/ec2/EC2Client.h>
#include <aws/ec2/model/DescribeInstancesRequest.h>

Hasil paged; Anda bisa mendapatkan hasil lebih lanjut dengan meneruskan nilai yang dikembalikan dari `GetNextToken` fungsi objek hasil ke fungsi objek permintaan asli Anda, kemudian menggunakan objek permintaan yang sama dalam panggilan berikutnya. `SetNextToken` `DescribeInstances`

## Aktifkan Pemantauan Instance
<a name="enable-instance-monitoring"></a>

Anda dapat memantau berbagai aspek instans Amazon EC2 Anda, seperti pemanfaatan CPU dan jaringan, memori yang tersedia, dan ruang disk yang tersisa. Untuk mempelajari lebih lanjut tentang pemantauan instans, lihat [Memantau Amazon EC2](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/monitoring_ec2.html) di Panduan Pengguna Amazon EC2.

Untuk mulai memantau instance, Anda harus membuat [MonitorInstancesRequest](https://docs.aws.amazon.com/sdk-for-cpp/latest/api/aws-cpp-sdk-ec2/html/class_aws_1_1_e_c2_1_1_model_1_1_monitor_instances_request.html)dengan ID instance untuk dipantau, dan meneruskannya ke `MonitorInstances` fungsi EC2 Klien.

 **Termasuk** 

```
#include <aws/ec2/EC2Client.h>
#include <aws/ec2/model/MonitorInstancesRequest.h>
#include <aws/ec2/model/UnmonitorInstancesRequest.h>
#include <iostream>
```

 **Kode** 

```
    Aws::EC2::EC2Client ec2Client(clientConfiguration);
    Aws::EC2::Model::MonitorInstancesRequest request;
    request.AddInstanceIds(instanceId);
    request.SetDryRun(true);

    Aws::EC2::Model::MonitorInstancesOutcome dryRunOutcome = ec2Client.MonitorInstances(request);
    if (dryRunOutcome.IsSuccess()) {
        std::cerr
                << "Failed dry run to enable monitoring on instance. A dry run should trigger an error."
                <<
                std::endl;
        return false;
    } else if (dryRunOutcome.GetError().GetErrorType()
               != Aws::EC2::EC2Errors::DRY_RUN_OPERATION) {
        std::cerr << "Failed dry run to enable monitoring on instance " <<
                  instanceId << ": " << dryRunOutcome.GetError().GetMessage() <<
                  std::endl;
        return false;
    }

    request.SetDryRun(false);
    Aws::EC2::Model::MonitorInstancesOutcome monitorInstancesOutcome = ec2Client.MonitorInstances(request);
    if (!monitorInstancesOutcome.IsSuccess()) {
        std::cerr << "Failed to enable monitoring on instance " <<
                  instanceId << ": " <<

## Nonaktifkan Pemantauan Instance
<a name="disable-instance-monitoring"></a>

Untuk menghentikan pemantauan instance, buat [UnmonitorInstancesRequest](https://docs.aws.amazon.com/sdk-for-cpp/latest/api/aws-cpp-sdk-ec2/html/class_aws_1_1_e_c2_1_1_model_1_1_unmonitor_instances_request.html)dengan ID instance untuk menghentikan pemantauan, dan meneruskannya ke `UnmonitorInstances` fungsi EC2 Klien.

 **Termasuk** 

```
#include <aws/ec2/EC2Client.h>
#include <aws/ec2/model/MonitorInstancesRequest.h>
#include <aws/ec2/model/UnmonitorInstancesRequest.h>
#include <iostream>
```

        return false;
    } else if (dryRunOutcome.GetError().GetErrorType() !=
               Aws::EC2::EC2Errors::DRY_RUN_OPERATION) {
        std::cout << "Failed dry run to disable monitoring on instance " <<
                  instanceId << ": " << dryRunOutcome.GetError().GetMessage() <<
                  std::endl;
        return false;
    }

    unrequest.SetDryRun(false);

    if (!unmonitorInstancesOutcome.IsSuccess()) {
        std::cout << "Failed to disable monitoring on instance " << instanceId
                  << ": " << unmonitorInstancesOutcome.GetError().GetMessage() <<
