Hi Eriko,
CCA by default has an attribute mapping already set to export the 'os_name' (Linux) to the 'server_type' SDM attribute.
The option to export the Details of the OS is not available as there is a character limitation (16 characters) in CMDB.
If you have the MDR button configured in CMDB, you can click on the button which will open up the CCA UI where the user can review the OS details if it already discovered by CCA Network profile discovery.
Regards,
Kevin
