Thanks very much. Guys.
Yeah, I configured sFlow and attached br0 to it. It information is as follows:
_uuid : 62e112ce-6728-43e0-b6e0-2c490d9c6ab9
agent : "eth4"
external_ids : {}
header : 128
polling : 10
sampling : 64
targets : ["10.1.2.3:6343"]
I installed Host sFlow in the same server which OVS is running and started the
service. Then I ping from a virtual machine in the subnet connected by one port
on br0 to the subnet connected by the other port. The sFlow data that collector
received is like this:

It seems just contain the sflow data about the server which the Host sFlow was
installed but no data about the network usage. Did I miss something?
Besides, when I ran "ifconfig br0 10.0.0.1/24", it said that the device br0 can
not be found. Moreover, in hsflowd.auto file, the agentIP and agent is eth2,
which is one port that I connected to br0. Does this make sense in my case?
Thanks a lot.

Did you actually configure sFlow? The commands you listed below don't indicate
that. You should either look at the example in ovs-vsctl (and read the
ovs-vswitchd.conf.db man page) or follow Peter Phaal's suggestion.
