@jeanbisutti Thanks for the reply, the error got resolved. But still i am not able to see any logs on OTEL Collector. Just want to know where i can put the endpoint , servicename, log level etc. when I am adding the attributes in log4j2 configuration under otelappender , it is giving error for invalid attributes

@mohit32573 The available settings are described here: https://github.com/open-telemetry/opentelemetry-java-instrumentation/blob/main/instrumentation/log4j/log4j-appender-2.17/library/README.md#settings-for-the-log4j-appender

Have you followed this documentation?
