Subject: STATS: Add more hierarchy to counters.
X-Git-Tag: v18.07-rc1~166
X-Git-Url: https://gerrit.fd.io/r/gitweb?a=commitdiff_plain;h=1ec0ea85c3f57f4638e32a00396057f80d958ec9;hp=1ec0ea85c3f57f4638e32a00396057f80d958ec9;p=vpp.git

STATS: Add more hierarchy to counters.

Put error counters under node_index.
/err/<node-name>/<error-name>

E.g:
/err/ip4-lookup/Hash table collisions
/err/ip6-rewrite/Buffer allocation error

Error names are not globally unique, and this allows
for walking all errors for a particular node.

Put interface counters under the directory /if.
E.g. /if/rx

Put system counters under the directory /sys.
E.g. /sys/vector_rate
