Simple Log Service:Utiliser l'opération GetHistograms pour interroger la distribution des journaux

• Simple Log Service est activé.

• Le SDK Simple Log Service pour Python est initialisé.

Cet exemple utilise l'endpoint public de Simple Log Service pour la région Chine (Hangzhou) : https://cn-hangzhou.log.aliyuncs.com.

Pour accéder à Simple Log Service depuis d'autres services Alibaba Cloud situés dans la même région que votre projet, utilisez l'endpoint interne de Simple Log Service : https://cn-hangzhou-intranet.log.aliyuncs.com.

Pour plus d'informations sur les régions et les endpoints pris en charge par Simple Log Service, consultez la rubrique Endpoint.
