From 148c7b768721231325a349fa82db693190513b53 Mon Sep 17 00:00:00 2001 From: Ole Troan Date: Wed, 7 Oct 2020 18:05:37 +0200 Subject: stats: counters data model This adds a new data model for counters. Specifying the errors severity and unit. A later patch will update vpp_get_stats to take advantage of this. Only the map plugin is updates as an example. New .api language: A new "counters" keyword to define counter sets. counters map { none { severity info; type counter64; units "packets"; description "valid MAP packets"; }; bad_protocol { severity error; type counter64; units "packets"; description "bad protocol"; }; }; Each counter has 4 keywords. severity, which is one of error, info or warn. A type, which is one of counter64 or gauge64. units, which is a text field using units from YANG. paths { "/err/ip4-map" "map"; "/err/ip6-map" "map"; "/err/ip4-t-map" "map"; "/err/ip6-t-map" "map"; }; A new paths keyword that maps the counter-set to a path in the stats segment KV store. Updated VPP CLI to include severity so user can see error counter severity.
