Just setup additional backends for each interesting vhost:

backend www.a.example.com
(...)

backend www.b.example.com
(...)

backend default

frontend X
(...)

         acl host_www.a.example.com hdr(host) -i www.a.example.com
         acl host_www.b.example.com hdr(host) -i www.b.example.com

 	use_backend www.a.example.com if host_www.a.example.com
 	use_backend www.b.example.com if host_www.b.example.com

 	default_backend default

... and use your favorite method to get counters from the statistics. In most current snapshots you may use SNMP for this, README is located in: "contrib/netsnmp-perl/". You should also consider adding some constant ids for backends.

There are also two xmls for Cacti (haproxy_backend.xml, haproxy_frontend.xml) in that directory.
