+option:--vgid[='VGROUP'[,'VGROUP']...]::
+ For each 'VGROUP' argument, add 'VGROUP' to the virtual group ID
+ inclusion set of the selected recording session and domain.

++
+--
+* The real group ID (see man:getgid(3)) of a process as seen
+ from the user namespace (see man:user_namespaces(7)).
+
+* A group name.
++
+The connected LTTng session daemon (see man:lttng-sessiond(8)) performs
+the group name resolution on addition to the virtual group ID inclusion
+set.
