Disable user_code logs on engine

It is possible via Log4j API. But not in the log4jconfig.xml as the logger name is dynamic.

The following class does what you want. You could create an AutoStartEventBean which runs periodically to ensure that this code is executed after a server start and also if a new PMV was deployed.

import ch.ivyteam.di.restricted.DiCore;
import ch.ivyteam.ivy.application.IApplicationConfigurationManager;
import ch.ivyteam.ivy.application.IProcessModelVersion;
import ch.ivyteam.ivy.application.RuntimeLogCategory;
import ch.ivyteam.ivy.environment.Ivy;
import ch.ivyteam.log.Logger;

public class RuntimeLogMuter {

    public static void mute()
    {
        IApplicationConfigurationManager appManager = DiCore.getGlobalInjector().getInstance(IApplicationConfigurationManager.class);
        for(IProcessModelVersion pmv : appManager.getProcessModelVersions())
        {
            Logger log = pmv.getRuntimeLog(RuntimeLogCategory.USER);
            Ivy.log().warn("Muted logger "+log.getName());
            log.setLevel(Level.OFF);
        }
    }

}
