lvs-metrics's Issues

make bin err

when i make bin , exception happened,like :

go build -i -ldflags "-X github.com/mesos-utility/lvs-metrics/g.Version=" -o lvs-metrics .

github.com/mesos-utility/lvs-metrics/vendor/github.com/google/seesaw/netlink

could not determine kind of name for C.nl_socket_alloc
could not determine kind of name for C.nl_socket_free
make: *** [bin] Error 2

what can i do for this? thanks!

Post metrics twice when tranfer data to server

Here is my cfg.json
{ "debug": false, "attachtags": "", "http": { "enable": false, "listen": "0.0.0.0:1987" }, "transfer": { "enable": true, "addr": "http://127.0.0.1:8433", "interval": 3, "timeout": 1000 } }
127.0.0.1:8433 is a server that handle lvs-metrics data
I will get two request every tranfer，one is the collect data and another get 0 for all metrics.
Like this：
[{"endpoint":"localhost.localdomain","metric":"lvs.vip.inpkts","value":338884,"step":3,"counterType":"COUNTER","tags":"vip=192.168.65.11,port=80","timestamp":1536128359}]

[{"endpoint":"localhost.localdomain","metric":"lvs.in.packets","value":0,"step":3,"counterType":"GAUGE","tags":"","timestamp":1536128359}]

Why not collect data for each RS

Hi, One question. For the connections, bytes and packets, why not collect data for each RS？
Like the 'ipvsadm -l --rate' command, this command can outputs the metrics for each RS.

make bin fail!!!!!
