Network Response Input Plugin

The input plugin test UDP/TCP connections response time and can optional verify text in the response.


# Collect response time of a TCP or UDP connection
  ## 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"

  ## Uncomment to remove deprecated fields; recommended for new deploys
  # fielddrop = ["result_type", "string_found"]

type NetResponse

type NetResponse struct {
	Address     string
	Timeout     config.Duration
	ReadTimeout config.Duration
	Send        string
	Expect      string
	Protocol    string

NetResponse struct

func (*NetResponse) Gather

func (n *NetResponse) Gather(acc telegraf.Accumulator) error

Gather is called by telegraf when the plugin is executed on its interval. It will call either UDPGather or TCPGather based on the configuration and also fill an Accumulator that is supplied.

func (*NetResponse) SampleConfig

func (*NetResponse) SampleConfig() string

func (*NetResponse) TCPGather

func (n *NetResponse) TCPGather() (map[string]string, map[string]interface{}, error)

TCPGather will execute if there are TCP tests defined in the configuration. It will return a map[string]interface{} for fields and a map[string]string for tags

func (*NetResponse) UDPGather

func (n *NetResponse) UDPGather() (map[string]string, map[string]interface{}, error)

UDPGather will execute if there are UDP tests defined in the configuration. It will return a map[string]interface{} for fields and a map[string]string for tags

type ResultType

type ResultType uint64
const (
	Success          ResultType = 0
	Timeout          ResultType = 1
	ConnectionFailed ResultType = 2
	ReadFailed       ResultType = 3
	StringMismatch   ResultType = 4
