Global configuration options <!-- @/docs/includes/plugin_config.md -->

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
