usage: lttng add-context -t TYPE

If no channel and no event is given (-c/-e), the context
will be added to all events and all channels.
Otherwise the context will be added only to the channel (-c)
and/or event (-e) indicated.
Exactly one domain (-k/--kernel or -u/--userspace) must be specified.

Options:
  -h, --help               Show this help
      --list-options       Simple listing of options
  -s, --session NAME       Apply to session name
  -c, --channel NAME       Apply to channel
  -e, --event NAME         Apply to event
  -k, --kernel             Apply to the kernel tracer
  -u, --userspace          Apply to the user-space tracer
  -t, --type TYPE          Context type. You can repeat that option on
                           the command line to specify multiple contexts at once.
                           (--kernel preempts --userspace)

usage: lttng add-context -t TYPE

If no channel and no event is given (-c/-e), the context
will be added to all events and all channels.
Otherwise the context will be added only to the channel (-c)
and/or event (-e) indicated.
Exactly one domain (-k/--kernel or -u/--userspace) must be specified.

Options:
  -h, --help               Show this help
      --list-options       Simple listing of options
  -s, --session NAME       Apply to session name
  -c, --channel NAME       Apply to channel
  -e, --event NAME         Apply to event
  -k, --kernel             Apply to the kernel tracer
  -u, --userspace          Apply to the user-space tracer
  -t, --type TYPE          Context type. You can repeat that option on
                           the command line to specify multiple contexts at once.
                           (--kernel preempts --userspace)
