+event record is lost and saves this count to the trace. Since
+LTTng{nbsp}2.8, in overwrite mode, LTTng writes to a given sub-buffer
+its sequence number within its data stream. With a <<local-mode,local>>,
+<<net-streaming-mode,network streaming>>, or <<live-mode,live>>
+<<tracing-session,tracing session>>, a trace reader can use such
+sequence numbers to report lost packets. In overwrite mode, LTTng
+doesn't write to the trace the exact number of lost event records in
+those lost sub-buffers.
