Hey all, I wanted to see if my math makes sense for converting total traffic amounts to bit rate using sampled netflow.
Converting bytes (total) to bits per second (throughput) using sampled netflow rough estimate: netflow sample rate: 1:500 bytes (after sampling): 3639786 bytes (before sampling): 500 * 3639786 = 1,819,893,000 bits total : 1,819,893,000 * 8 = 14559144000 bps : 14559144000 / 300 = 48530480 48,530,480 (48Mbps) formula = bytes * sample rate (500) * 8 [conversion to bits] / time of netflow sample (300) This is just a general estimation, not an exact figure, i get that but is there any way to make it more accurate (anyone see a glaring problem with it?) thanks, -Drew
