Hello Team,
would like to check if there is a way to check severity setting in remote syslog server?
The only "UCS" I can think of is Cisco Unified Computing System. I have no idea how you would be "connected to UCS domain" (maybe you're talking about some speciffic add-on, I have no idea).
Typically if you're a syslog receiver, you're just a receiver and sender's settings are beyond your reach.
