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();
