[logback-user] question about start-up process and disabling auto-configuration

Hello Rob,

There should be no status messages printed during automatic (default) 
configuration, unless errors occur.

Are you saying that automatic configuration using logback.xml fails because of 
missing variables which you fill in when you call doConfigure()?

If you know how to find the configuration file, why don't you rename 
"logback.xml" to something else so that it does not get picked up?

BTW, there is no way to disable automatic configuration. However, you can set a 
system property to specify a different configuration file URL.
For more details, search for "Specifying the location of the default 
configuration file as a system property" in http://logback.qos.ch/manual/joran.html
