3 Buffers monitoring plugin
4 =========================
6 This plugin enables to track buffer utilization in the VPP graph nodes.
7 The main use is to detect buffer leakage. It works by keeping track of
8 number of buffer allocations and free in graph nodes and also of number
9 of buffers received in input frames and in output frames. The formula to
10 compute the number of “buffered” buffers in a node is simply: #buffered
11 = #alloc + #input - #free - #output Note: monitoring will impact
17 1. Turn buffer traces on:
21 ~# vppctl set buffer traces on
23 2. Monitor buffer usage:
27 ~# vppctl show buffer traces verbose
29 3. Turn buffer traces off:
33 ~# vppctl set buffer traces off
