We want to use splunk-library-javalogging to send logs via Log4j  to Splunk Service Environment:  Spark with log4j2 in Azure Databricks ----> Splunk Enterprise The config file log4j2.xml  <?xml version="1.0" encoding="UTF-8"?><Configuration status="INFO" packages="com.splunk.logging,com.databricks.logging.log4j" shutdownHook="disable"> <Appenders> ... <SplunkHttp name="http-input" url="https://url-service" token="xxxx-xxxx-xxxx-xxx-xxx--xxxx" host="" index="my-index" source="spark-work" sourcetype="httpevent" messageFormat="text" middleware="HttpEventCollectorUnitTestMiddleware" connect_timeout="5000" termination_timeout="1000" disableCertificateValidation="true"> <PatternLayout pattern="%m%n"/> </SplunkHttp> </Appenders> <Loggers> <Root level="INFO"> ... </Root> ... <Logger name="splunk.log4j" level="DEBUG"> <AppenderRef ref="http-input"/> </Logger> </Loggers> </Configuration>   We use the library splunk-library-javalogging: splunk-library-javalogging-1.11.8.jar with okhttp-4.11.0.jar okio-3.5.0.jar okio-jvm-3.5.0.jar Currently we based the configuration from this example: https://github.com/splunk/splunk-library-javalogging/blob/main/src/test/resources/log4j2.xml Currently it doesn't work. We checked HEC via curl send a message from  Databricks to Splunk HEC and receive without problem. Does anyone have any experience or can help us with some guidance or advice? Thanks ... View more
