There is no option to ipvsadm to do that, but SysAdmin 101 would have
you do something like this:

For RIP == 192.168.1.2 port 80

ipvsadm -Lnc | egrep -c "ESTABLISHED.+192.168.1.2:80"

To make it even more fine-grained, for example if you have many VIPs
using the same RIPs:

For For RIP == 192.168.1.2 port 80, VIP == 192.168.0.10 port 80

ipvsadm -Lnc | egrep -c "ESTABLISHED.+192.168.0.10:80.+192.168.1.2:80"
