# ipvsadm -L -n

TCP  192.168.1.1:80 wlc
  -> 192.168.1.2:80            Route   1      50          1005

In my LVS has many real server ip address (RIP) and I'd like to get ActiveConn value of some RIP to calculate.
I'd like to know how ipvsadm to get only ActiveConn value by identifying RIP x.x.x.x ? 

Ex: I put RIP=192.168.1.2 and it return 1005 to me 
(I try lot of ipvsadm options, but didn't work.)
or which file that contain that value? 
 
Thank you in advance,
