Overview

The ForwardingLogger provides a wrapper to control the OpenTelemetry log level, while respecting the configured level of the supplied logger. If the OTEL_LOG_LEVEL is set to debug, and the supplied logger is configured with an ERROR log level, only OpenTelemetry logs at the ERROR level or higher will be emitted.
