Example Input Plugin

The input plugin test UDP/TCP connections response time. It can also check response text.

Configuration:

[[inputs.net_response]]
  protocol = "tcp"
  address = ":80"

# TCP or UDP 'ping' given url and collect response time in seconds
[[inputs.net_response]]
  ## Protocol, must be "tcp" or "udp"
  protocol = "tcp"
  ## Server address (default localhost)
  address = "github.com:80"
  ## Set timeout
  timeout = "1s"

  ## Optional string sent to the server
  send = "ssh"
  ## Optional expected string in answer
  expect = "ssh"
  ## Set read timeout (only used if expecting a response)
  read_timeout = "1s"

[[inputs.net_response]]
  protocol = "udp"
  address = "localhost:161"
  timeout = "2s"

Measurements & Fields:

• net_response
  • response_time (float, seconds)
  • string_found (bool) # Only if "expected: option is set

Tags:

• All measurements have the following tags:
  • server
  • port
  • protocol
