Add per packet profiling.
Per packet profiling uses tick based accounting. It has 2 outputs, a summary
and a csv file that contains per packet stats.
Stats per packet include:
1) total ticks spent
2) ticks spent per individual thread module
3) "threading overhead" which is simply calculated by subtracting (2) of (1).
A number of changes were made to integrate the new code in a clean way:
a number of generic enums are now placed in tm-threads-common.h so we can
include them from any part of the engine.
Code depends on --enable-profiling just like the rule profiling code.
New yaml parameters:
profiling:
# packet profiling
packets:
# Profiling can be disabled here, but it will still have a
# performance impact if compiled in.
enabled: yes
filename: packet_stats.log
append: yes
# per packet csv output
csv:
# Output can be disabled here, but it will still have a
# performance impact if compiled in.
enabled: no
filename: packet_stats.csv
Example output of summary stats:
IP ver Proto cnt min max avg
------ ----- ------ ------ ---------- -------
IPv4 6 19436 11448 5404365 32993
IPv4 256 4 11511 49968 30575
Per Thread module stats:
Thread Module IP ver Proto cnt min max avg
------------------------ ------ ----- ------ ------ ---------- -------
TMM_DECODEPCAPFILE IPv4 6 19434 1242 47889 1770
TMM_DETECT IPv4 6 19436 1107 137241 1504

TMM_STREAMTCP IPv4 6 19434 828 1299159 19438
The proto 256 is a counter for handling of pseudo/tunnel packets.
