Network Connection Statistics Input Plugin

This plugin collects statistics about TCP connection states and UDP socket counts.

Introduced in: Telegraf v0.2.0 Tags: network OS support: all

Global configuration options

Plugins support additional global and plugin configuration settings for tasks such as modifying metrics, tags, and fields, creating aliases, and configuring plugin ordering. See CONFIGURATION.md for more details.

Configuration

# Read TCP metrics such as established, time wait and sockets counts.
[[inputs.netstat]]
  # no configuration

Metrics

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

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

Measurement names:

  • udp_socket

Example Output

netstat tcp_close=0i,tcp_close_wait=0i,tcp_closing=0i,tcp_established=14i,tcp_fin_wait1=0i,tcp_fin_wait2=0i,tcp_last_ack=0i,tcp_listen=1i,tcp_none=46i,tcp_syn_recv=0i,tcp_syn_sent=0i,tcp_time_wait=0i,udp_socket=10i 1668520568000000000
