Methodology
- Attack =
[NHP-DROP];PASSis allowed traffic, shown only as a baseline. - Exact packet totals come from the per-minute
[NHP-STAT]lines (PKTS summed, duplicates removed). - Sampled counts come from per-packet lines, which the filter rate-limits per class; bulk classes may have none. Rankings (IP, geo, port) use sampled events and are not comparable in volume across classes.
- The log has no date per line; dates come from file names.
