The config file looks OK. Separating into different files per log level is probably not a good practice, but that is unrelated to the problem at hand. You also don't want to write logger.trace("Trace {} " + randomValue); but logger.trace("Trace {}", randomValue); instead. However, this is also unrelated to the problem at hand. I suspect that for one reason or another, logback is unable to compress the log file, possibly because another process is holding a lock on the file. When this happens, logback will complain by adding a status message in an internal buffer. To see logback's internal errors, you should stop printing messages on the console. Instead, add a status listener which will print status messages generated by logback. The code is: LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory(); ... // additional line of code loggerContext.getStatusManager().add(new OnConsoleStatusListener()); Also, in your messages consider "hello" as a salutation instead of "Dear sir". boss134 wrote:
