Websocket Output Plugin

This plugin can write to a WebSocket endpoint.

It can output data in any of the supported output formats.

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Secret-store support

This plugin supports secrets from secret-stores for the headers option. See the secret-store documentation for more details on how to use them.

Configuration

# A plugin that can transmit metrics over WebSocket.
[[outputs.websocket]]
  ## URL is the address to send metrics to. Make sure ws or wss scheme is used.
  url = "ws://127.0.0.1:3000/telegraf"

  ## Timeouts (make sure read_timeout is larger than server ping interval or set to zero).
  # connect_timeout = "30s"
  # write_timeout = "30s"
  # read_timeout = "30s"

  ## Optionally turn on using text data frames (binary by default).
  # use_text_frames = false

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

  ## Optional SOCKS5 proxy to use
  # socks5_enabled = true
  # socks5_address = "127.0.0.1:1080"
  # socks5_username = "alice"
  # socks5_password = "pass123"

  ## Optional HTTP proxy to use
  # use_system_proxy = false
  # http_proxy_url = "http://localhost:8888"

  ## Data format to output.
  ## Each data format has it's own unique set of configuration options, read
  ## more about them here:
  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
  # data_format = "influx"

  ## NOTE: Due to the way TOML is parsed, tables must be at the END of the
  ## plugin definition, otherwise additional config options are read as part of
  ## the table

  ## Additional HTTP Upgrade headers
  # [outputs.websocket.headers]
  #   Authorization = "Bearer <TOKEN>"

WebSocket can output to WebSocket endpoint.

func (*WebSocket) Close

func (w *WebSocket) Close() error

Close closes the connection. Noop if already closed.

func (*WebSocket) Connect

func (w *WebSocket) Connect() error

Connect to the output endpoint.

func (*WebSocket) Init

func (w *WebSocket) Init() error

Init the output plugin.

func (*WebSocket) SampleConfig

func (*WebSocket) SampleConfig() string

func (*WebSocket) SetSerializer

func (w *WebSocket) SetSerializer(serializer serializers.Serializer)

SetSerializer implements serializers.SerializerOutput.

func (*WebSocket) Write

func (w *WebSocket) Write(metrics []telegraf.Metric) error

Write writes the given metrics to the destination. Not thread-safe.
