2020-10-13stats: counters data modelOle Troan1-3/+18
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.

2019-07-23vlib: address vlib_error_t scaling issueDave Barach1-30/+0
Encoding the vpp node index into the vlib_error_t as a 10-bit quantity limits us to 1K graph nodes. Unfortunately, a few nodes need 6 bit per-node error codes. Only a very few nodes have so many counters. It turns out that there are about 2K total error counters in the system, which is (approximately) the maximum error heap index. The current (index,code) encoding limits the number of interfaces to around 250, since each interface has two associated graph nodes and we have about 500 "normal, interior" graph node This patch adds an error-index to node-index map, so we can store error heap indices directly in the vlib_buffer_t.
