SAP On Azure : Azure Enhanced Monitoring Extension for SAP in Windows

Introduction

The Azure Enhanced Monitoring Extension for SAP provides configuration information and performance data of the underlying Azure infrastructure and makes it available to the SAP application. It contains built-in self-diagnostics which enables identification of the health and completeness of the infrastructure data required by SAP services and support.

Having set up the Azure Enhanced Monitoring Extension for SAP, the Windows service AzureEnhancedMonitoring is installed inside the VM and collects all Azure-related data. Afterwards, this data is consumed by SAP Host Agent for further use in the SAP system transaction ST06.
