The Host sFlow agent ships with the sflowovsd daemon that automatically configures sFlow on Open vSwitch to match the Host sFlow settings (i.e. picking up sampling rates, polling intervals, sFlow collectors, ports etc).
Just run the following command and you should start receiving sFlow from all the physical and virtual ports on the Open vSwitch:
service sflowovsd start
The sflowovsd daemon will automatically maintain the Open vSwitch sFlow configuration as bridges are added / removed, on restarts etc. ensuring reliable monitoring in production settings.
Instructions for installing and configuring Host sFlow for different platforms are included on the Host sFlow web site (and in the README / INSTALL files that ship with the software):
http://host-sflow.sourceforge.net/documentation.php
There is a mailing list for the Host sFlow project if you have any questions:
https://lists.sourceforge.net/lists/listinfo/host-sflow-discuss

I also installed a Host sFlow on that server, but it just monitors the local server's performance. I am wondering how can I let the ovs send sflow data to the configured collector or how can I connect the Host sFlow to OVS to let it monitor the traffic on the virtual bridge. I will really appreciate if you can give me some advice. Thanks a lot.
