Noob Realtime Netflow question


I have been looking online and have been having a hard time finding quality directions for how to configure sFlow on an HP E3800 48 port 4SFP+ switch.  I found some directions from HP, but they weren't as helpful as one would have hoped.  I was wondering if anyone had a link to some detailed directions on how to configure sFlow on this type of switch.  Also, as this may be easier, can someone answer if you can use the Netflow Configurator to set this up via SNMP v3 or if it's only for Cisco equipment?  If it does work, maybe a quick link to directions on enabling SNMP v3 on my switch would also be appreciated.

Any direction or assistance would be appreciated at this point.  Thanks.
