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.}} ============================== This message was sent by Atlassian Jira (v8.8.0#808000-sha1:e2c7e59)
