+Read timer
+~~~~~~~~~~
+By default, an internal notification mechanism is used to signal a full
+sub-buffer so that it can be consumed. When such notifications must be
+avoided, for example in real-time applications, the channel's read timer
+can be used instead. When the read timer fires, sub-buffers are checked
+for consumption when they are full.
+
+Use the option:--read-timer option to control the read timer's period of
+the channel to create.
+
+
+Monitor timer
+~~~~~~~~~~~~~
+When a channel's monitor timer fires, its registered trigger conditions
+are evaluated using the current values of its properties (for example,
+the current usage of its sub-buffers). When a trigger condition is true,
+LTTng executes its associated action. The only type of action currently
+supported is to notify one or more user applications.
+
+See the installed $$C/C++$$ headers in `lttng/action`,
+`lttng/condition`, `lttng/notification`, and `lttng/trigger` to learn
+more about application notifications and triggers.
+
+Use the option:--monitor-timer option to control the monitor timer's
+period of the channel to create.
