[ovs-discuss] sFlow unsampling in openVswitch

2014-02-09 Thread Weiyu Liu
Hey, all. I am wondering if openVswitch supports sFlow unsampling. Or will setting the sampling parameter "sampling" in the ovs-vsctl command to 1 let the sflow agent get every packet through the monitored interface? I will really appreciate if you can give me some suggestion.

[ovs-discuss] Using OVS+Host sFlow to monitor network traffic

2013-12-01 Thread WEIYU LIU
Hey, all. I used OVS to create a bridge to connect two subnets. And then I created an sflow and attached it to the bridge. But it does not send sflow data to the collector. I also installed a Host sFlow on that server, but it just monitors the local server's performance. I am wondering how can
