AgentTracerProviderConfigurer#loggingExporterIsNotAlreadyConfigured

[chenjazz]

  private static boolean loggingExporterIsNotAlreadyConfigured() {
    return !Config.get().getString("otel.traces.exporter", "").equalsIgnoreCase("logging");
  }

Mybe otel.traces.exporter has serveral values,like otel.traces.exporter=otlp,logging

I think it should use getList() method instead of getString() method and use contains() method to determine whether the logging exporter has been configured.

I will fix it. Thanks for report.

hi @chenjazz @wallezhang! I thought that otel.traces.exporter doesn't support multiple values?

According to this document: https://github.com/open-telemetry/opentelemetry-java/tree/main/sdk-extensions/autoconfigure#exporters

The configuration support multiple values that separated by commas.
