Summary:              Logback config not honoring system property for log level
Issue Type:           Bug
Affects Versions:     1.2.3
Assignee:             Logback dev list
Attachments:          logback.xml
Components:           logback-classic
Created:              18/Jul/20 7:01 PM
Environment:          Linux Fedora 32, java 8, command-line app with loggers displaying on console
Priority:             Major
Reporter:             Phil Adams
Description:
  {{I have a java application that is run from the command line. I have my logback.xml file configured to display all messages on the console.}}
  
  {{In my logback.xml file, I have configured my logger like this:}}
  {quote}
  {{ <logger name="com.ibm.sdk.codegen" level="${SDKGEN_LOGLEVEL:-INFO}">}}
  {{   <appender-ref ref="STDOUT"/>}}
  {{   <appender-ref ref="STDERR"/>}}
  {{ </logger>}}
  {quote}
   
  
  I want the default log level to be INFO, but I also would like to allow users to specify "-DSDKGEN_LOGLEVEL=DEBUG" as part of the java command to enable debug logging.
  
   
  
  {{I'm following [these instructions|http://logback.qos.ch/manual/configuration.html] on how to do this, but I can't seem to get this to work.  I have some debugging code in my application that verifies the system property is being set as expected:}}
  {quote}{{[INFO ] c.i.s.c.IBMDefaultCodegen: SDKGEN_LOGLEVEL=DEBUG this.class=IBMJavaCodegen}}
  {quote}
   
  
  {{But logback-classic seems to not want to use that system property value.   What am i doing wrong?  :)}}
  
   
  
  {{I'll attach my full logback.xml file to this issue for reference.}}
