The easiest way to link the ifIndex numbers reported by sFlow in the Open vSwitch (OVS) with virtual machine host names is to run the Host sFlow agent on Dom0. As well as simplifying the configuration of sFlow on OVS, the Host sFlow agent uses the xenstat library to report on virtual machine performance and link virtual machines to the OVS ports. http://blog.sflow.com/2010/08/sflow-host-structures.html
For instructions on installing Host sFlow on XCP 0.5, see: http://blog.sflow.com/2010/10/xcp-05.html The following example demonstrates the combination of OVS and Host sFlow provides visibility into traffic and virtual machine performance: http://blog.sflow.com/2010/10/sflowtrend-adds-server-performance.html Peter On Nov 12, 2010, at 12:31 PM, Cain NG wrote: > Hi, > > I configured the xen server with 2 network interface and I used sflow to > monitor the openvswitch traffic.
