          Possible values:
          - json:     Represents JSON formatting for logs. This format outputs log records as JSON objects, making it suitable for structured logging
          - log-fmt:  Represents logfmt (key=value) formatting for logs. This format is concise and human-readable, typically used in command-line applications
          - terminal: Represents terminal-friendly formatting for logs

          [default: terminal]

          The maximum size (in MB) of one log file

          [default: 200]

      --log.file.max-files <COUNT>
          The maximum amount of log files that will be stored. If set to 0, background file logging is disabled.

          Default: 5 for `node` command, 0 for non-node utility subcommands.

      --log.journald
          Write logs to journald

      --log.journald.filter <FILTER>

      --logs-otlp[=<URL>]
          Enable `Opentelemetry` logs export to an OTLP endpoint.

          If no value provided, defaults based on protocol: - HTTP: `http://localhost:4318/v1/logs` - gRPC: `http://localhost:4317`

          Example: --logs-otlp=http://collector:4318/v1/logs

          [env: OTEL_EXPORTER_OTLP_LOGS_ENDPOINT=]

      --logs-otlp.filter <FILTER>
          Set a filter directive for the OTLP logs exporter. This controls the verbosity of logs sent to the OTLP endpoint. It follows the same syntax as the `RUST_LOG` environment variable.

          Example: --logs-otlp.filter=info,reth=debug

          Defaults to INFO if not specified.

          [default: info]

Display:
  -v, --verbosity...
          Set the minimum log level.

          -v      Errors
          -vv     Warnings
          -vvv    Info
          -vvvv   Debug
          -vvvvv  Traces (warning: very verbose!)

  -q, --quiet
          Silence all log output

Tracing:
      --tracing-otlp[=<URL>]
          Enable `Opentelemetry` tracing export to an OTLP endpoint.

          If no value provided, defaults based on protocol: - HTTP: `http://localhost:4318/v1/traces` - gRPC: `http://localhost:4317`

          Example: --tracing-otlp=http://collector:4318/v1/traces

          [env: OTEL_EXPORTER_OTLP_TRACES_ENDPOINT=]

      --tracing-otlp-protocol <PROTOCOL>
          OTLP transport protocol to use for exporting traces and logs.

          - `http`: expects endpoint path to end with `/v1/traces` or `/v1/logs` - `grpc`: expects endpoint without a path

          Defaults to HTTP if not specified.

          Possible values:
          - http: HTTP/Protobuf transport, port 4318, requires `/v1/traces` path
          - grpc: gRPC transport, port 4317

          [env: OTEL_EXPORTER_OTLP_PROTOCOL=]
          [default: http]

      --tracing-otlp.filter <FILTER>
          Set a filter directive for the OTLP tracer. This controls the verbosity of spans and events sent to the OTLP endpoint. It follows the same syntax as the `RUST_LOG` environment variable.

          Example: --tracing-otlp.filter=info,reth=debug,hyper_util=off

          Defaults to TRACE if not specified.

          [default: debug]

      --tracing-otlp.sample-ratio <RATIO>
          Trace sampling ratio to control the percentage of traces to export.

          Valid range: 0.0 to 1.0 - 1.0, default: Sample all traces - 0.01: Sample 1% of traces - 0.0: Disable sampling

          Example: --tracing-otlp.sample-ratio=0.0.
