Configuration

You can configure the agent to collect and process various metrics from OpenTelemetry.

Agent​

  • otel_grpc_server_enabled Boolean

    Default true

    Enable the Grpc server to receive the data delivered via the OpenTelemetry protocol (OTLP).

  • otel_grpc_server_port String

    Default 6600

    Listening port of the Grpc server.

    Note

    After changing the port number, be sure to restart the whatap-otel service.

  • otel_grpc_server_gzip_enabled Boolean

    Default true

    It enables gzip by encrypting the data from the Grpc server.

  • debug_otel_grpc_server_enabled Boolean

    Default false

    It enables the output of debugging logs for processing the OpenTelemetry Trace data.

Trace​

Agent setting option for processing the OpenTelemetry Trace data. WhaTap gets values from the attributes object of Span, an OpenTelemetry Trace element, and uses them as monitoring information.

See the following code to see how the attributes object of Span relates to the WhaTap's agent configuration.
