Microsoft Entra logs contain the history of sign-in activity and an audit trail of changes made in Microsoft Entra ID for a particular tenant.
The features of Microsoft Entra monitoring and health provide a comprehensive view of identity related activity in your environment.
Sign-in and audit logs comprise the activity logs behind many Microsoft Entra reports, which can be used to analyze, monitor, and troubleshoot activity in your tenant.
Types of activity logs in Microsoft Entra ID:
Sign-in logs: Capture the sign-in attempts of your users and client applications.
Audit logs: A comprehensive report on every logged event in Microsoft Entra ID.
