WebSocket

The WebSocket input connects to a remote WebSocket server as a client, decodes each inbound message, and forwards it into the pipeline. The current implementation supports client mode only.

Configuration

Field	Type	Required	Default	Description
type	string	yes	—	Constant value "websocket"
url	string	yes	—	WebSocket server URL, e.g. ws://host:8080/path or wss://host:8443/path
headers	map<string, string>	no	—	Request headers attached during the handshake
timeout	integer	no	—	Connection timeout (seconds)

Examples

input:
  type: "websocket"
  url: "ws://localhost:8080/ws"

input:
  type: "websocket"
  url: "wss://secure.example.com/ws"
  headers:
    Authorization: "Bearer ${TOKEN}"
  timeout: 10

Notes

• Client mode only: the component actively calls connect_async against url; it does not listen on a port. Server-side fields such as mode/host/port/path do not exist in the code, and the related descriptions from the old docs have been removed.
• Automatically attaches the __meta_source and __meta_ingest_time metadata columns.
