Exports spans to an OpenTelemetry collector using the OTLP protocol over gRPC or HTTP. Defaults to gRPC on localhost:4317. Switch to HTTP by setting transport: http (default port 4318, default path /v1/traces). Set secured: true to use HTTPS. Custom request headers can be added for hosted collectors that require authorization.

Example Configuration

global:
   - openTelemetry:
       otlpExporter:
         host: localhost
         port: 4317
         transport: grpc

global:
   - openTelemetry:
       otlpExporter:
         host: localhost
         port: 4317
         transport: grpc

Syntax

otlpExporter:
  headers:
    - <addHeader>
  host: <string>
  path: <string>
  port: <number>
  secured: <boolean>
  transport: <string>

Attributes

Name	Required	Default	Description	Examples
host	false	localhost	Hostname or IP address of the OTLP collector.	collector.example.com
path	false	(empty)	URL path appended to the collector endpoint. For HTTP transport defaults to `/v1/traces` when left empty.	-
port	false	-	Port of the OTLP collector. When omitted, defaults to 4317 for gRPC and 4318 for HTTP.	4317
secured	false	false	Whether to use a secure (TLS) connection. When `true`, the endpoint URL scheme is set to `https` for HTTP transport and causes the gRPC client to use TLS as well.	-
transport	false	grpc	Wire protocol for delivering spans: `grpc` or `http`.	http

Child Structure

Element	Cardinality	Description
addHeader	0..*	HTTP headers sent with every span export request. Only effective when `transport` is `http`. Useful for authorization headers required by hosted collectors.
