This counter tracks how many established sessions belonging to this group were terminated by an explicit management action, whether triggered locally by an admin or requested by the peer itself, per the desc. An admin auditing session terminations for this group can distinguish intentional shutdowns (like using crasSessionState to disconnect a user, or a client-initiated logoff) from the abnormal terminations tracked elsewhere. A count that jumps right after a scheduled maintenance window, when admins manually disconnected all users in that group, would explain an otherwise unusual spike.
