在 Amazon 警报中使用 CloudWatch 警报操作（AWS SDK for PHP版本 3）

利用警报操作创建自动停止、终止、重启或恢复 Amazon EC2 实例的警报。当不再需要某个实例运行时，您可使用停止或终止操作。使用重启和恢复操作可以自动重启这些实例。

以下示例演示如何：

的所有示例代码都可以在此AWS SDK for PHP处找到 GitHub。

凭证

运行示例代码之前，请配置您的 AWS 凭证，如 凭证 中所述。然后导入 AWS SDK for PHP，如 基本用法 中所述。

启用警报操作

导入

require 'vendor/autoload.php';

use Aws\CloudWatch\CloudWatchClient;
use Aws\Exception\AwsException;

示例代码

function enableAlarmActions($cloudWatchClient, $alarmNames)
{
    try {
        $result = $cloudWatchClient->enableAlarmActions([
            'AlarmNames' => $alarmNames
        ]);

        if (isset($result['@metadata']['effectiveUri'])) {
            return 'At the effective URI of ' .
                $result['@metadata']['effectiveUri'] .
                ', actions for any matching alarms have been enabled.';
        } else {
            return'Actions for some matching alarms ' .
                'might not have been enabled.';
        }
    } catch (AwsException $e) {
        return 'Error: ' . $e->getAwsErrorMessage();
    }
}

function enableTheAlarmActions()
{
    $alarmNames = array('my-alarm');

    $cloudWatchClient = new CloudWatchClient([
        'profile' => 'default',
        'region' => 'us-east-1',
        'version' => '2010-08-01'
    ]);

    echo enableAlarmActions($cloudWatchClient, $alarmNames);
}

// Uncomment the following line to run this code in an AWS account.
// enableTheAlarmActions();

禁用警报操作

导入

require 'vendor/autoload.php';

use Aws\CloudWatch\CloudWatchClient;
use Aws\Exception\AwsException;

示例代码

function disableAlarmActions($cloudWatchClient, $alarmNames)
{
    try {
        $result = $cloudWatchClient->disableAlarmActions([
            'AlarmNames' => $alarmNames
        ]);

        if (isset($result['@metadata']['effectiveUri'])) {
            return 'At the effective URI of ' .
                $result['@metadata']['effectiveUri'] .
                ', actions for any matching alarms have been disabled.';
        } else {
            return 'Actions for some matching alarms ' .
                'might not have been disabled.';
        }
    } catch (AwsException $e) {
        return 'Error: ' . $e->getAwsErrorMessage();
    }
}

function disableTheAlarmActions()
{
    $alarmNames = array('my-alarm');

    $cloudWatchClient = new CloudWatchClient([
        'profile' => 'default',
        'region' => 'us-east-1',
        'version' => '2010-08-01'
    ]);

    echo disableAlarmActions($cloudWatchClient, $alarmNames);
}

// Uncomment the following line to run this code in an AWS account.
// disableTheAlarmActions();
