There was an error in the man page, the command should be "lttng snapshot add-output". I've just sent a patch to fix this. Also you don't need to use add-output/del-output if you want to change to default snapshot output location. It can be specified with the create session command and -U option: lttng create mySession --snapshot -U file:///home/taung/output [...] lttng snapshot record -n snapshot_name Also see doc/snapshot-howto.txt for a complete example.
