Logging & job progress

Watch your job progress thanks to live updates

Some jobs take a very long time to complete - generating 1000’s of emails, do a batch import of some large xml or CSV files, … . How to know whether your code is actually running and doing it’s actual job (pun intended)?

Say hello to job logging and the job progress bar.

Watch logging appear live from your actual job


JobRunr supports logging to the dashboard - new messages will appear as they’re logged, it is as if you’re looking at a real console. To log something in the dashboard, you have two options:

  • you can use the JobContext and use it’s logger:
    jobContext.logger().info('this will appear in the dashboard');
  • or - even easier - wrap your existing Logger as follows:
    new JobRunrDashboardLogger(LoggerFactory.getLogger(MyService.class))

The last logger will make sure that all info, warn and error statement will be shown in the dashboard for each job. Debug logging is not supported as I want to prevent to spam the various browsers.

Progress bar

Long running jobs take time - and sometimes you need to know how long a job will take. Thanks to the progress bar in JobRunr, you can now track progress from within the dashboard - a progress bar will appear automatically just below the ‘Processing job’ header and advance while work is progressing.

To use this feature, you will need to inject the JobContext into your job: BackgroundJob.enqueue(() -> myService.doWork(JobContext.Null)).

Inside your actual job, you can then use the JobContext to create a progress bar:

public class MyService {

	public void doWork(JobContext jobContext) {
    	JobDashboardProgressBar progressBar = jobContext.progressBar(1000);
        for(int i = 0; i < 1000; i++) {
        	//do actual work
            // or you can also use
