Aria Operations 8.18.x
As there is no functionality to forward logs through Log Forwarding configuration choosing Azure Sentinel in Aria Operations for logs, the option would be to use either CFAPI or Syslog protocol as per documentation Add a VMware Aria Operations for Logs Log Forwarding Destination. However this is dependent on whether the protocols are supported by Microsoft. Please reach Microsoft to confirm that the Azure Sentinel supports the available protocols.
