I am not clear what your use case here is, as unsure if you mean logins to the device CLI or that something is connected.
If the former, that is not something that UDT is designed to capture, as that is more of a SIEM solution or at least Syslog or use of NCM to track the configuration changes users apply.
With UDT capturing data used in NAC solutions such as hardware, IP, DNS and Username of a device attached to a switch port, this may be of use, but we need clarity on what you are trying to achieve.
I understand in UDT you can add a Active Directory to track user logins, but that is more for Windows server. So is it possible to add a Cisco ISE to track user logins for network devices instead?
OK, so I understand what you are trying to achieve.
No, there is no native support for you to capture login data from Cisco ISE, only Windows AD is supported. I have had a look and there are no API verbs that you can leverage to perform this function via the Orion API either I am afraid.
Time for you to create a feature request I would suggest.
