There was a problem hiding this comment.
sampled_ipv4.length is one packet's IP length (at most 65,535), but it's set to the flow's total Bytes. A goflow2 collector reported bytes: 911685, packets: 1, sampling_rate: 1024, so each sample counts as about 933 MB.

Proposed Change
Adds a fourth signal type,
FlowRecord, with NetFlow/IPFIX/sFlow generation. Key decisions:logspbwith flow semantic conventions matched tonetflowreceiver.Validated by round-trip against
netsampler/goflow2v2.2.6 (CI test-only).Checklist
