Yes, setting the sampling-rate to 1-in-1 will give you every packet header, along with the attendant meta-data. Useful for testing, even if you would never use it in production. Neil -- Neil McKee InMon Corp. http://www.inmon.com On Sun, Feb 9, 2014 at 7:54 PM, Weiyu Liu wrote: >

Was DNS Server-Discovery ever considered as a way for an Open VSwitch to find it's controller? We just implemented this for the host-sflow daemon and it seems to work well. The daemon is identical on every server, but you can change the settings for the whole data-center just by tweaking one
