For determining what ciphers are used by individual vServers, in on-prem ADM I choose:
Web Insight
Click the vServer
Scroll all the way down
Click the Ciphers button
After one or more ciphers below that button are revealed, click on one
This may not be what you're looking for, but I had trouble finding this info a few years ago after an ADM upgrade and had to call Citrix to find it again. It does give me the cipher names.
