Which Azure AD feature helps identify synchronization errors?

Azure AD Connect Health is the feature specifically designed to monitor the health of Azure Active Directory (Azure AD) Connect and its sync processes. This feature provides insights and alerts regarding synchronization errors that may occur during the syncing of on-premises Active Directory with Azure AD.

By using Azure AD Connect Health, administrators gain visibility into performance metrics and potential issues, allowing them to respond promptly to any problems that could impact the authentication or access of users relying on Azure AD. It helps track synchronization activity, provides alerts for failures, and offers diagnostic reports that can assist in quickly identifying the root causes of synchronization errors.

Other options, though useful in their own areas, do not specifically cater to identifying synchronization errors related to Azure AD. Azure Monitor focuses on performance monitoring and machine health across Azure services, while Azure Security Center is tailored to security management and threat protection. Azure Automation is primarily for automating repetitive tasks and processes within Azure, lacking the specific capabilities for monitoring AD synchronization.
