Configure gRCP clients

To configure gRCP clients in exporters use these settings:

• auth. See Configure authentication

• balancer_name

  • Defaults: pick_first before version 0.103.0, round_robin for v0.103.0 or higher

  • Learn more at gRCP’s Load Balancing README .

• compression

  • Compression type valid values are gzip, snappy, zstd, and none

• endpoint

  • For valid syntax see gRPC Name Resolution .

• headers

• keepalive

• read_buffer_size

• tls. See Configure TLS.

• write_buffer_size

For example:

exporters:
   otlp:
      endpoint: otelcol2:55690
      auth:
         authenticator: some-authenticator-extension
      tls:
         ca_file: ca.pem
         cert_file: cert.pem
         key_file: key.pem
      headers:
         test1: "value1"
         "test 2": "value 2"
