How to Implement loggers for debuging

[amrit1993]

Dear Community,

I have a sampleToolboxConfigurationPresenter class for my Toolbox configuration, as below:

public class sampleToolboxConfigurationPresenter extends samplePresenter {

    private final Dao<sampleToolboxConfigurationDto> dao = new GenericSlingDao<sampleToolboxConfigurationDto>(sampleToolboxConfigurationDto.class);

    /** {@inheritDoc} */

    @Override

    public sampleToolboxConfigurationModel getModelFromResource(SlingHttpServletRequest request,Resource resource) {

        sampleToolboxConfigurationDto dto = dao.getDtoOrNewOnError(resource);

        return new sampleToolboxConfigurationModel(dto);

    }

}

Could you please let me know In The above code How can I get the attributes of  dto by using the loggers .And how can I use the loggers for debuging.

To log messages in AEM - you simply create an instance of http://www.slf4j.org/api/org/slf4j/Logger.html:

/** Default log. */
protected final Logger log = LoggerFactory.getLogger(this.getClass());

then write out what you want: 

log.debug("This will log out");

See this community article that logs messages:

Hi Scott,

Thanks for your quick reply.

I added the log in my SampleToolboxConfigurationPresenter class file, as shown below.

public class SampleToolboxConfigurationPresenter extends AbstractPresenter {
    
    protected final Logger LOG = LoggerFactory.getLogger(this.getClass());

    private final Dao<SampleToolboxConfigurationDto> dao = new GenericSlingDao<SampleToolboxConfigurationDto>(
            SampleToolboxConfigurationDto.class);

    /** {@inheritDoc} */
    @Override
    public SampleToolboxConfigurationModel getModelFromResource(SlingHttpServletRequest request,
            Resource resource) {
        
        LOG.debug("This will log out");
        LOG.info("Temperature has risen above 50 degrees.");
        
        SampleToolboxConfigurationDto dto = dao.getDtoOrNewOnError(resource);
        return new SampleToolboxConfigurationModel(dto);
    }
    
   
}

But I am not bale to see my log entry in any of the files.

access.log , history.log , request.log

Thanks,

Sonu

Its error.log - that is where its written too.

Have you changed Logger log mode?. You should change it to debug mode from OSGI config to get debug message in log file.

Hi Jitendra,

I did not changed Logger log mode?.

You should change it to debug mode from OSGI config to get debug message in log file.

https://docs.adobe.com/docs/en/aem/6-1/deploy/configuring/configure-logging.html

I followed the adobe document but did not understand much.

Could you please send me the screenshot, how can I change it in OSGI config.

Thanks,

It should state in the AEM docs that you need to go here: 

http://localhost:4502/system/console/configMgr

Look for Apache Sling Logging Configuration - as shown here: 

Hope this helps
