42 * [Intro]
43 * This file defines new statistics infrastructure using enum and uin64_t array
44 * for skywalk. BSD network stack statistics definition would be kept for
45 * backward compatibility.
46 *
47 * This new scheme has several advantages over legacy statistics definition.
48 * 1. Using array based data structure allows efficient folding with vector
49 * instructions.
50 * 2. It also allows simple indexing of statistics field using enum value
51 * rather than struct field name.
52 * 3. Coupled with descriptive string per statistics enum, it allows convenient
53 * printing.
54 *
55 * The new statistics enum and data structure follows naming convention as:
56 * 1. It should resemble legacy names to make transition easy.
57 * 2. It should be easily distinguishable from legacy data structure.
58 *
59 *
60 * [Naming]
61 * The new data structures are named with suffix _stats (plural) v.s legacy stat
62 * and are always in snake case, e.g.
63 * New | Legacy
64 * -------------------------+--------------------------
65 * ip_stats | ipstat
66 * ip6_stats | ip6stat
67 * tcp_stats | tcpstat
68 * if_tcp_ecn_stats | if_tcp_ecn_stat
69 * if_tcp_ecn_perf_stats | if_tcp_ecn_perf_stat
70 * udp_stats | udpstat
71 *
72 *
73 * Enums are named as <stats_family>_<type>, e.g.
74 * New | Legacy
75 * -------------------------+--------------------------
76 * IP_STATS_TOTAL | ipstat.ips_total
77 * TCP_STATS_CONNATTEMPT | tcpstat.tcps_connattempt
78 *
79 *
80 * [Usage]
81 * Declare a statistics data structure:
82 *
83 * struct ip_stats sample_ip_stats;
84 *
85 * To increment a statistics value by one:
86 *
87 * STATS_INC(&sample_ip_stats, IP_STATS_TOTAL);
88 *
89 * To add to a statistics value by a certain value:
90 *
91 * STATS_ADD(&sample_ip_stats, IP_STATS_TOTAL, n_pkts);
92 *
93 * To fold one statistics data structure into another one:
94 *
95 * ip_stats_fold(&sample_ip_stats, &another_ip_stats);
96 *
97 * To reset statistics:
98 *
99 * ip_stats_reset(&sample_ip_stats);
100 *
101 *
102 * [Note]
103 * Some legacy stats member has been removed for convenience reason, e.g.
104 *
105 * ip6stat.ip6s_nxthist[256]
106 * ip6stat.ip6s_sources_sameif[SCOPE6_ID_MAX];
107 *
108 * are removed, as they don't have easy mapping into array based statistics
109 * scheme and doesn't have explicit usage within the kernel.
110 * That's been said, those are treated as exceptions and could be reconsidered
111 * if they are needed in the future.
112 *
113 *
114 * [Adding Stats]
115 * To add new stats definition, a X-Macro table and STATS_REGISTER is needed.
116 *
117 * #define NEW_STATS_TABLE(X)\
118 * X(sub_type_1, "sub_type_1_short_name", "sub_type_1_fmt_string")\
119 * X(sub_type_2, "sub_type_2_short_name", "sub_type_2_fmt_string")\
120 * X(__NEW_STATS_MAX, "", "")
121 *
122 * STATS_REGISTER(new_stats, NEW_STATS);
123 *
124 * where new_stats is the lower case name, and NEW_STATS is its upper case.
125 * The following would be generated by STATS_REGISTER Macro:
126 *
127 * enum _new_stats {
128 * sub_type_1,
129 * sub_type_2,
130 * __NEW_STATS_MAX,
131 * };
132 *
133 * struct new_stats {
134 * uint64_t _arr[__NEW_STATS_NEW];
135 * }
136 *
137 * static inline const char* new_stats_str(enum _new_stats);
138 * static inline const char* new_stats_fmt(enum _new_stats);
139 *
140 * static inline void __attribute__((always_inline))
141 * new_stats_fold(struct new_stats *dst, struct new_stats *src);
142 *
143 * static inline void __attribute__((always_inline))
144 * new_stats_reset(struct new_stats *s);
145 *
146 * The fmt_string should conform to printf convention. Note here as uint64_t is
147 * used to store stats value, `%llu` is used to format the print value (PRIu64
148 * could be used but since long long is guaranteed to be 64bit long, casting
149 * to llu should work well without introducing definitions from `inttypes.h`.
