Zack Zatkin-Gold dd537b3382 Fix telegraf example arguments (#2788) 
Many of the examples provided within documentation are using a single
dash for the command line arguments, but the telegraf executable
explicitly has two dashes.

There are also some inconsistencies with the ordering of the command
line argument examples.  I've ordered them so that the examples will
show: config, config-directory, input-filter, test

Example Input Plugin

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

Configuration:

[[inputs.net_response]]
  ## Protocol, must be "tcp" or "udp"
  ## NOTE: because the "udp" protocol does not respond to requests, it requires
  ## a send/expect string pair (see below).
  protocol = "tcp"
  ## Server address (default localhost)
  address = "localhost:80"
  ## Set timeout
  timeout = "1s"

  ## Set read timeout (only used if expecting a response)
  read_timeout = "1s"

  ## The following options are required for UDP checks. For TCP, they are
  ## optional. The plugin will send the given string to the server and then
  ## expect to receive the given 'expect' string back.
  ## string sent to the server
  # send = "ssh"
  ## expected string in answer
  # expect = "ssh"

[[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"
  send = "hello server"
  expect = "hello client"

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
