Abrufen von Metriken von Amazon CloudWatch mit AWS SDK for PHP Version 3

Metriken sind Daten über die Leistung Ihrer Systeme. Sie können die detaillierte Überwachung einiger -Ressourcen aktivieren, z. B. Ihrer Amazon EC2-Instances oder Ihrer eigenen Anwendungsmetriken.

In den nachstehenden Beispielen wird Folgendes veranschaulicht:

Der gesamte Beispielcode für die AWS SDK for PHP ist hier auf GitHubverfügbar.

Anmeldeinformationen

Bevor Sie den Beispielcode ausführen, konfigurieren Sie Ihre AWS Anmeldeinformationen, wie unter beschriebenAnmeldeinformationen. Importieren Sie dann die AWS SDK for PHP, wie unter beschriebenGrundlegende Verwendung.

Auflisten von Metriken

Importe

require 'vendor/autoload.php'; use Aws\CloudWatch\CloudWatchClient; use Aws\Exception\AwsException;

Beispiel-Code

function listMetrics($cloudWatchClient) { try { $result = $cloudWatchClient->listMetrics(); $message = ''; if (isset($result['@metadata']['effectiveUri'])) { $message .= 'For the effective URI at ' . $result['@metadata']['effectiveUri'] .
