When enabled xt_coova, inputOctets cann't count correctly 2 time invoke json api, interval of 30s, http://172.25.0.1:3990/json/status first result: {"version":"1.0","clientState":1,"redir":{"originalURL":"","redirectionURL":"","logoutURL":"http://172.25.0.1:3990/logoff","ipAddress":"172.25.1.70","macAddress":"3C-A2-F4-1B-48-BC"},"session":{"sessionId":"5676d58a00000030","userName":"3C-A2-F4-1B-48-BC","startTime":1450628836,"sessionTimeout":0,"terminateTime":0,"idleTimeout":1800},"accounting":{"sessionTime":39815,"idleTime":0,"inputOctets":4009,"outputOctets":1952267900,"inputGigawords":0,"outputGigawords":5,"viewPoint":"client"}}

inputOctets value is not total throughput, but 1 second throughput likely.

I have "inputOctets":0 for all time of session, but sometimes it jumps about 156 and returns to 0

See if it makes a difference with TSO/GSO/GRO disabled on WAN or LAN:

ethtool -K eth0 gso off gro off tso off

and/or;

ethtool -K eth1 gso off gro off tso off

replace eth0 with WAN and eth1 with LAN port.
