connections per VH

[Neil Mckee]

There is an sFlow module here:
http://nginx-sflow-module.googlecode.com

described here:
http://blog.sflow.com/2011/04/nginx.html

transactions are sampled at 1-in-N (to minimize the overhead) and send via UDP to an sFlow collector for further analysis.  For example, the freeware "sflowtool" can turn it into an ascii feed in common-logfile-format.

sFlow agents are also available for servers/hypervisors  (http://host-sflow.sourceforge.net);  and for most ethernet switches (http://sflow.org/products/network.php) so you might find you can instrument the system in other ways too.
