Receives trace data in Jaeger format.

By default, the Jaeger receiver will not serve any protocol. A protocol must be named under the protocols object for the jaeger receiver to start. The below protocols are supported, each supports an optional endpoint object configuration parameter.

• grpc (default endpoint = 0.0.0.0:14250)
• thrift_binary (default endpoint = 0.0.0.0:6832)
• thrift_compact (default endpoint = 0.0.0.0:6831)
• thrift_http (default endpoint = 0.0.0.0:14268)

The component.UseLocalHostAsDefaultHost feature gate changes these endpoints to localhost:14250, localhost:6832, localhost:6831 and localhost:14268. This will become the default in a future release.

Examples:

receivers:
  jaeger:
    protocols:
      grpc:
  jaeger/withendpoint:
    protocols:
      grpc:
        endpoint: 0.0.0.0:14260

UDP protocols (currently thrift_binary and thrift_compact) allow setting additional server options:

• queue_size (default 1000) sets max not yet handled requests to server
• max_packet_size (default 65_000) sets max UDP packet size
• workers (default 10) sets number of workers consuming the server queue
• socket_buffer_size (default 0 - no buffer) sets buffer size of connection socket in bytes

Examples:

protocols:
  thrift_binary:
    endpoint: 0.0.0.0:6832
    queue_size: 5_000
    max_packet_size: 131_072
    workers: 50
    socket_buffer_size: 8_388_608

Several helper files are leveraged to provide additional capabilities automatically:

• gRPC settings including CORS
• TLS and mTLS settings

Since version v0.61.0, remote sampling is no longer supported by the jaeger receiver. Since version v0.59.0, the jaegerremotesapmpling extension is available that can be used instead.
