break telegraf registry into separate package 
this is for supporting external plugins.

external plugins will depend on a few telegraf interface types, as well
as a common telegraf registry.

this will allow external and internal plugins to both share this package
and make it easier to vendor/version the whole thing semantically, which
will make it easier to keep plugins supported across build and telegraf
versions.

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
