+Buffers monitoring plugin
+=========================
+
+This plugin enables to track buffer utilization in the VPP graph nodes.
+The main use is to detect buffer leakage. It works by keeping track of
+number of buffer allocations and free in graph nodes and also of number
+of buffers received in input frames and in output frames. The formula to
+compute the number of “buffered” buffers in a node is simply: #buffered
+= #alloc + #input - #free - #output Note: monitoring will impact
+performances.
+
+Basic usage
+-----------
+
+1. Turn buffer traces on:
+
+::
+
+ ~# vppctl set buffer traces on
+
+2. Monitor buffer usage:
+
+::
+
+ ~# vppctl show buffer traces verbose
+
+3. Turn buffer traces off:
+
+::
+
+ ~# vppctl set buffer traces off
