Configuring the Target Profiling Server

Before you perform the operations in Starting the Trace Forwarding Process, set the target profiling server through environment variables.

The following four protocols are supported:

• HTTP

  export OTEL_EXPORTER_OTLP_PROTOCOL="http/protobuf"
  export OTEL_EXPORTER_OTLP_ENDPOINT=http://xxx:xxx/v1/traces    # Configure the IP address and port number for data forwarding, for example, http://localhost:4318/v1/traces.

• HTTP + TLS

  export OTEL_EXPORTER_OTLP_PROTOCOL="http/protobuf"
  export OTEL_EXPORTER_OTLP_ENDPOINT=https://xxx:xxx/v1/traces    # Configure the IP address and port number for data forwarding, for example, https://localhost:4318/v1/traces.
  export OTEL_EXPORTER_OTLP_CERTIFICATE=/home/certificates/ca/ca.crt    # Set the absolute path of the certificate. The directory owner, file owner, and current user match. The directory permission is 700 and the file permission is 600.

• gRPC

  export OTEL_EXPORTER_OTLP_PROTOCOL="grpc"
  export OTEL_EXPORTER_OTLP_ENDPOINT=http://xxx:xxx    # Configure the IP address and port number for data forwarding, for example, http://localhost:4317.

• gRPC + TLS

  export OTEL_EXPORTER_OTLP_PROTOCOL="grpc"
  export OTEL_EXPORTER_OTLP_ENDPOINT=https://xxx:xxx    # Configure the IP address and port number for data forwarding, for example, https://localhost:4317.
  export OTEL_EXPORTER_OTLP_CERTIFICATE=/home/certificates/ca/ca.crt    # Set the absolute path of the certificate. The directory owner, file owner, and current user match. The directory permission is 700 and the file permission is 600.
