I am currently using Spring Boot Admin to manage a Spring Boot application. SBA exposes correctly the logs of the application in the tab "Log". As part of transitioning the deployment to Docker I would like to continue forwarding our logs to stdout and ELK, but to stop logging to a rotating log file.
After removing from Spring Boot application.properties file the property "logging.file" I could check that, as expected, the rotating log file was not created. However this configuration change had the side-effect of removing from SBA the "Log" tab exposing the logs.
My question is: is there any way I could still expose logs through Spring Boot Admin without having to have a log file for the application?
Spring Boot admin needs the logfile acuator endpoint. The endpoint needs a file on the disk. It either serves the file from loging.file or endpoint.logfile.external-file.
Here is a simple workaround: Add a link to a kibana query for the application (or similar) to your info endpoint l. It is rendered as hyperlink in SBA. This would be a convenient way for the users to find the log output.
