Telegraf plugin: NETSTAT

Description

The NETSTAT plugin collects TCP connections state and UDP socket counts by using lsof.

Supported TCP Connection states are follows.

  • established
  • syn_sent
  • syn_recv
  • fin_wait1
  • fin_wait2
  • time_wait
  • close
  • close_wait
  • last_ack
  • listen
  • closing
  • none

Measurements:

TCP Connection State measurements:

Meta:

  • units: counts

Measurement names:

  • tcp_established
  • tcp_syn_sent
  • tcp_syn_recv
  • tcp_fin_wait1
  • tcp_fin_wait2
  • tcp_time_wait
  • tcp_close
  • tcp_close_wait
  • tcp_last_ack
  • tcp_listen
  • tcp_closing
  • tcp_none

If there are no connection on the state, the metric is not counted.

UDP socket counts measurements:

Meta:

  • units: counts
