  title: SAP HANA Cloud REST Alerts API
  description: REST API for managing SAP HANA Cloud instances, monitoring alerts, accessing metrics, and retrieving metering data. The API uses the SAP Service Manager framework to provision, configure, start, stop, and delete SAP HANA Cloud database instances within SAP Business Technology Platform subaccounts. Additionally, the alerts and metrics endpoints provide access to triggered alerts, database performance metrics, and consumption metering data for SAP HANA Cloud, SAP HANA database and SAP HANA Cloud, data lake instances.
