+option:--blocking-timeout:
+    Set the channel's blocking timeout value to 'TIMEOUTUS' µs. 0
+    (default) does not block. -1 blocks forever until room is
+    available in the buffer to write the event. Positive
+    values are a timeout bounding the maximum blocking time
+    when trying to write into the buffer. Note that this option
+    only affects applications launched with the
+    LTTNG_UST_ALLOW_BLOCKING environment variable set.
