Netstat Input Plugin

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

Configuration:

# Collect TCP connections state and UDP socket counts
[[inputs.netstat]]
  # no configuration

Measurements:

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
