Hi All,

Anyone successful able to pull the logs (Sign-in and Audit logs) of Active Directory via Azure Event Hub. If yes which method you follow.

Any other recommendation method. Thanks in advance

Yes. Here's how:

1. Install the Azure Monitor Add-on https://github.com/Microsoft/AzureMonitorAddonForSplunk/wiki (don't forget to get the node.js and Python dependencies)
2. Setup all your Azure stuff (Event Hubs, Azure AD applications, Key Vault, SPNs)
   • Easy way = run a script -> https://github.com/microsoft/AzureMonitorAddonForSplunk/tree/master/scripts
   • Manual way = https://www.splunk.com/blog/2018/04/20/splunking-microsoft-azure-monitor-data-part-1-azure-setup.htm...
3. Send your Azure AD sign-in and audit logs to an Event Hub
4. Modify your hubs.json file in the add-on -> https://github.com/microsoft/AzureMonitorAddonForSplunk/wiki/Configuration-of-Splunk#hubsjson
   • Basically, after you enable the Azure AD logs going to an event hub, check the event hubs in the Azure portal for the name of the actual hub(s). It will be something like insights-logs-signinlogs and insights-logs-auditlogs
5. Setup and Azure Monitor Diagnostic Logs input on the Splunk instance where you installed the Azure Monitor add-on
6. Done

Thanks @jconger it worked.

Can we define sourcetype for sign and audit logs as currently sourcetype is defined which is amdl:diagnosticLogs.

Yes - modify logCategories.json

Thanks for quick reply @jconger , you mean i need to update "MICROSOFT.AADIAM/AUDIT" OR "MICROSOFT.AADIAM/SIGNIN" with ?

"MICROSOFT.AADIAM/AUDIT": "amdl:aadal:audit",
"MICROSOFT.AADIAM/SIGNIN": "amdl:aadal:signin"
