2020-08-19vppinfra: minor tweaks for cgo interoperationDave Barach1-1/+1
'type' is a keyword in golang, so s/type/event_type/ in elog.h and elsewhere. Add vec_len_not_inline(...), elog_write_file_not_inline(...) and elog_read_file_not_inline(...) since the inline forms aren't usable. More such tweaks may follow.

2019-02-03Automated anomaly detectionDave Barach2-220/+540
Compute per-track mean, variance, and n*stddev stats for the first u32 datum in each instance of the supplied event. Search for the next instance of the indicated event which has a datum larger than mean + n*stddev. This turns out to be a very effective "Nixon Gap" finder when the selected event datum is the instantaneous vector size. Such traces can be easily captured from production vpp images.

2017-04-01Clean up event log merge codeDave Barach1-2/+5
Fix a decade-old ridiculous qsort function bug. Managed to subtract floating-point numbers as if they were integers, leading to manufactured time-paradoxes. That completely confuses g2, leading to the summary disappearance of entire tracks' worth of data at high zoom levels. Add a manual alignment tweak parameter to elog_merge, users can dial-out time paradoxes caused by NTP-grade clock synchronization. The event-logger has a precision of O(100ns), whereas NTP synchronization is O(1ms). Change-Id: I69dedabaa314f69f9df74ec9ee66e21e6c87f703 Signed-off-by: Dave Barach <dave@barachs.net>
