             Summary: Add configuration setting for logback logging verbosity level
                 Key: GUACAMOLE-713
                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-713
             Project: Guacamole
          Issue Type: New Feature
          Components: guacamole-client
            Reporter: Joel Best


I've noticed during my troubleshooting process that it is cumbersome to enable debug logging for guacamole, especially when using docker. Currently to enable debug logging, I start the container and then replace the setting in the default logback.xml file with this command:

 
{code:java}
sed -i 's/level="info"/level="debug"/' /usr/local/tomcat/webapps/guacamole/WEB-INF/classes/logback.xml
{code}
I then restart the container. I know I can also copy logback.xml to GUACAMOLE_HOME but this is easier for the docker use case.

 

I think it would be better if there was a guacamole.properties setting for the logback level. E.g.:

logback-level: [trace|debug|info|warn|error]

For my Docker use case, I think this is the best solution as I can then use set_optional_property in start.sh to populate this setting.

 

Alternatively, I would propose that the Docker start.sh script checks for an environment variable (LOGBACK_LEVEL?) and copies and modifies the logback settings directly. E.g.
{code:java}
if [ -n "$LOGBACK_LEVEL" ]; then
    unzip -o -j /opt/guacamole/guacamole.war WEB-INF/classes/logback.xml -d $GUACAMOLE_HOME
    sed -i "s/level=\"info\"/level=\"$LOGBACK_LEVEL\"/" $GUACAMOLE_HOME/logback.xml
fi
{code}
It's less elegant, but it works for my use case.

Thoughts?
