Google Spanner

Présentation

Google Cloud Spanner est le seul service de base de données relationnelle à disposer d’une cohérence forte et d’une évolutivité horizontale.

Recueillez des métriques de Google Spanner pour :

  • Visualiser les performances de vos bases de données Spanner
  • Corréler les performances de vos bases de données Spanner avec vos applications

Configuration

Collecte de métriques

Installation

Si vous ne l’avez pas déjà fait, configurez d’abord l’intégration Google Cloud Platform. Aucune autre procédure d’installation n’est requise.

Collecte de logs

Les logs Google Cloud Spanner sont recueillis avec Google Cloud Logging et envoyés à un Cloud Pub/Sub via un forwarder Push HTTP. Si vous ne l’avez pas déjà fait, configurez un Cloud Pub/Sub à l’aide d’un forwarder Push HTTP.

Une fois cette opération effectuée, exportez vos logs Google Cloud Spanner depuis Google Cloud Logging vers le Pub/Sub :

  1. Accédez à la page Google Cloud Logging et filtrez les logs Google Cloud Spanner.

  2. Cliquez sur Create Sink et nommez le récepteur.

  3. Choisissez Cloud Pub/Sub comme destination et sélectionnez le Pub/Sub créé à cette fin. Remarque : le Pub/Sub peut se situer dans un autre projet.

    Exporter les logs Google Cloud Pub/Sub vers le Pub Sub
  4. Cliquez sur Create et attendez que le message de confirmation s’affiche.
