Bytes in/out not correct

[zliucd]

Hi,

I'm using Joy to analyze flow. The bytes in/out output json file are not correct(orders of magnitude difference), by viewing same statistics in Wireshark. Please let me know if Joy was not properly used.

My usage of Joy:
joy bidir=1 tls=1 dist=1 zeros=1 retrans=1 xx.pcap | gunzip >joy_result.json

Thanks.
