this other [admittedly-much-simpler] "web portal" can "pull" logs from drones that have companion computer/s on them [eg an embedded pi or nvidia-jetson style device]... vis rsync-over-ssh.. and it can also run 2 different log-analysis tools on each newly-arrived log, and display critical flight such as time-in-air, distance-traveled, date, vehicle type, git hash, firmware-type, wether there was any mission onboard, if there were any fence breaches, gps type, etc...
