2019-02-04g2-only: add (min,max) stats to the anomaly detectorDave Barach1-5/+25
Shows up on the status line. Change-Id: I14635f7406069a4a868bdb7c8b85da941c49dbba Signed-off-by: Dave Barach <dave@barachs.net>
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>
