This extension accepts HTTP requests, optionally adds headers to them and forwards them. The RequestURIs of the original requests are preserved by the extension.

Configuration

The following settings are required:

• egress: HTTP config settings to use for forwarding requests.
  • endpoint (no default): The target to which requests should be forwarded to.

The following settings can be optionally configured:

• ingress: HTTP config settings for HTTP server listening to requests.
  • endpoint (default = 0.0.0.0:6060): The host to which requests should be forwarded to.
• egress: HTTP config settings to use for forwarding requests.
  • headers (default = nil): Additional headers to be added to all requests passing through the extension.
  • timeout (default = 10s): How long to wait for each request to complete.

Example

  http_forwarder:
    ingress:
      endpoint: localhost:7070
    egress:
      endpoint: http://target/
      headers:
        otel_http_forwarder: dev
      timeout: 5s

The full list of settings exposed for this exporter are documented here with detailed sample configurations here.
