  21 previously enabled with the man:lttng-enable-channel(1) command
  22 which belong to:
  23
  24 With the option:--session='SESSION' option::
  25     The recording session named 'SESSION'.
  26
  27 Without the option:--session option::
  28     The current recording session (see man:lttng-concepts(7) to learn
  29     more about the current recording session).
  30
  31 See man:lttng-concepts(7) to learn more about channels.

  34 argument.

  36 As of LTTng{nbsp}{lttng_version}, you may :not: enable a disabled
  37 channel once its recording session has been started (see
  38 man:lttng-start(1)) at least once.
