Netstat report incorrect values

[cdgraff]

I has running netstat plugin in telegraf running as ROOT, to avoid privileges issue reported into other issue.

But only get ESTABLISHED metrics, and the counts is not correct.

root@ubuntu:~# telegraf -config /etc/telegraf/telegraf.conf -input-filter netstat -test

• Plugin: netstat, Collection 1

  netstat tcp_close=0i,tcp_close_wait=0i,tcp_closing=0i,tcp_established=9834i,tcp_fin_wait1=0i,tcp_fin_wait2=0i,tcp_last_ack=0i,tcp_listen=8i,tcp_none=0i,tcp_syn_recv=0i,tcp_syn_sent=0i,tcp_time_wait=0i,udp_socket=1i 1455827518629788254

root@ubuntu:~# netstat -nap | grep ESTABLI | wc -l
13840

And is not reporting any other value, at this moment i has +20k time_wait connections and can see that plugin don't report any value there.

some advice? or tests to run for help with debug?
