You are right, the stats doesn't seem accurate in my case too. I tested it by sending 100k packets for 5 runs and below is 'n_packets' count in dump-flows output. Reported | Actual 97206 | 100,000 97833 | 100,000 97954 | 100,000 98334 | 100,000 98017 | 100,000 Regards, Bhanu Prakash. >Could you please help verify if you have obtained accurate results for your >case? > >Thanks, >An >________________________________________ >发件人: Bodireddy, Bhanuprakash <bhanuprakash.bodire...@intel.com> >发送时间: 2016年8月1日 15:59:13 >收件人: awan...@masonlive.gmu.edu; discuss@openvswitch.org >主题: RE: help - ovs 2.5 flow statistics issues > >>-----Original Message----- >>From: discuss [mailto:discuss-boun...@openvswitch.org] On Behalf Of >>awan...@masonlive.gmu.edu >>Sent: Wednesday, July 27, 2016 3:14 PM >>To: discuss@openvswitch.org >>Subject: [ovs-discuss] help - ovs 2.5 flow statistics issues >> >>Hi, All, >> >>I am running openvswitch 2.5.0 on Ubuntu 14.04 LTS with kernel 3.13.0-92- >>generic. >>I installed the two following rules to the switch: >> >>NXST_FLOW reply (xid=0x4): >> cookie=0x0, duration=2.183s, table=0, n_packets=0, n_bytes=0, idle_age=2, >>priority=50000,ip,in_port=1,nw_src=10.0.0.0/8,nw_dst=81.0.0.0/8 >>actions=output:2 >> cookie=0x0, duration=10.829s, table=0, n_packets=0, n_bytes=0, >>idle_age=10, in_port=1 actions=output:2 >> >>Another host machine connecting to the switch generates traffic (including >>10.0.0.0/8 -> 81.0.0.0/8) that goes through the switch. >>However, the statistics were not be updated correctly with n_packets for >the >>higher priority rule remaining 0 while all the traffic statistics being >>credited to >>the lower priority rule. >>But if I modify the rules to be: >> >>NXST_FLOW reply (xid=0x4): >> cookie=0x0, duration=2.183s, table=0, n_packets=0, n_bytes=0, idle_age=2, >>priority=50000,ip,in_port=1,nw_src=10.0.0.0/8 actions=output:2 >> cookie=0x0, duration=10.829s, table=0, n_packets=0, n_bytes=0, >>idle_age=10, in_port=1 actions=output:2 >> >>Then it works fine.
