I guess a separate logger specifically for this purpose is another way to approach it alright - definitely worth considering. I think I'm gonna try extending the existing ThresholdFilter (or creating a new filter based on it) as a first attempt, see how that goes, and failing that try the separate logger route. Good to have options.</div>

First I considered using markers on each initialization log message. Then I used a logger dedicated exclusively for initialization. This dedicated logger was configured to log everything, regardless of other loggers.<br>
<br>Both solutions, markers or dedicated logger, require you to handle the initialization messages differently and to provide proper configuration for them. IMHO, the approach of a dedicated logger is much simpler to understand and to configure.<br>

Folks,<div><br></div><div>Just wondering if there is a capability within Logback for writing a log message regardless of whatever log level has been set in configuration. Consider the scenario where I want my web application to output some diagnostic information at startup or shutdown - for example, the Web Application version, build date etc. If I were to set the log level of these messages to be TRACE, DEBUG, or INFO then its possible they may never be displayed since the app may typically be configured to run with a log level of WARN. Similarly, I don't want to set the log level of the messages to WARN, ERROR or FATAL in order to ensure that they do get displayed since they're not really error messages, and if we monitor the log files for WARN, ERROR or FATAL messages then this would trigger a false positive.</div>
<div><br></div><div>So, is there some way to force a message to be logged at all times, independently of log level? Or some way to achieve this effect via existing configuration. Arguably I suppose this is bending the rules slightly, in that it could be abused - why offer the ability to filter certain log levels if an application can override/ignore them - but perhaps this is something which could be configurable/switchable?</div>
