2020-11-04vlib: add postmortem pcap dispatch traceDave Barach5-14/+92
Inspired by a real-life conundrum: scenario X involves a vpp crash in ip4-load-balance because vnet_buffer(b)->ip.adj_index[VLIB_TX] is (still) set to ~0. The problem takes most of a day to occur, and we need to see the broken packet's graph trajectory, metadata, etc. to understand the problem. Fix a signed/unsigned ASSERT bug in vlib_get_trace_count(). Rename elog_post_mortem_dump() -> vlib_post_mortem_dump(), add dispatch trace post-mortem dump. Add FILTER_FLAG_POST_MORTEM so we can (putatively) capture a ludicrous number of buffer traces, without actually using more than one dispatch cycle's worth of memory.

2020-10-13stats: counters data modelOle Troan5-27/+76
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.
