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)

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

The Jaeger receiver also supports fetching sampling configuration from a remote collector. It works by proxying client requests for remote sampling configuration to the configured collector.

    +------------+                   +-----------+              +---------------+
    |            |       get         |           |    proxy     |               |
    |   client   +---  sampling ---->+   agent   +------------->+   collector   |
    |            |     strategy      |           |              |               |
    +------------+                   +-----------+              +---------------+

Remote sample proxying can be enabled by specifying the following lines in the jaeger receiver config:

receivers:
  jaeger:
    protocols:
      grpc:
    remote_sampling:
      endpoint: "jaeger-collector:14250"
      tls:
        insecure: true

Remote sampling can also be directly served by the collector by providing a sampling json file:

receivers:
  jaeger:
    protocols:
      grpc:
    remote_sampling:
      strategy_file: "/etc/strategy.json"
      strategy_file_reload_interval: 10s

Note: the grpc protocol must be enabled for this to work as Jaeger serves its remote sampling strategies over gRPC.
