Docker seems to output each line to splunk (using the --log-driver=splunk) to a separate event because it treats each line as an event. I have somewhat solved this by using log4j2 to output each log item to json, so it now spits out the entire stacktrace in a json wrapped line. I'm using: < JSONLayout compact = "true" stacktraceAsString = "true" eventEol = "true" /> This works for the most part until I get to searching in splunk. My logger now outputs something like this for an exception: {"instant":{"epochSecond":1593534200,"nanoOfSecond":461000000},"thread":"http-nio-8080-exec-1","level":"ERROR","loggerName":"org.apache.catalina.core.ContainerBase.[Tomcat].[localhost].[/].[dispatcherServlet]","message":"Servlet.service()

Using splunk 8.0.2.1 I have a container (spring boot that uses tomcat underneath) that I'm running that I'm attempting to push the contents to the HEC. I'm starting the container like this: docker run --name test-spring-boot-app --publish 8080:8080 --log-driver=splunk --log-opt splunk-token=SOME-TOKEN --log-opt splunk-url=http://ec2-someip.compute-1.amazonaws.com:8088 --log-opt splunk-format=inline --log-opt splunk-sourcetype=log4j-test test-spring-boot-app I can't for the life of me get ingested logs to merge multi-line events. The Exception in the log below shows up as a single event for every line even though I've tried every combination I can think of to try to get it to merge. It almost appears that it is ignoring my source type. I have the token in HEC selected with the log4j-test source type as well. My log output looks like this: . ____ _ __ _ _
/\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \
( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \
\\/ ___)| |_)| | | | | || (_| | ) ) ) )
