QuartzManager.java

public class QuartzManager implements Managed {

  private Scheduler scheduler;
  private QuartzSchedulerMonitor schedulerMonitor;
  private QuartzJobMonitor jobMonitor;

  public  QuartzManager(SchedulerFactory sf) throws SchedulerException {
    scheduler = sf.getScheduler();
    schedulerMonitor = new QuartzSchedulerMonitor(); // Implements SchedulerListener
    scheduler.getListenerManager().addSchedulerListener(schedulerMonitor);
    jobMonitor = new QuartzJobMonitor(); // Implements JobListener
  }

  @Override
  public void start() throws Exception {
    scheduler.start();
    // Make our Job listener cover all scheduled jobs
    scheduler.getListenerManager().addJobListener(jobMonitor, EverythingMatcher.allJobs());
  }

  @Override
  public void stop() throws Exception {
    scheduler.getListenerManager().removeJobListener(jobMonitor.getName());
    scheduler.shutdown(true);
  }
  
  public boolean isHealthy(){
    return schedulerMonitor.isHealthy() && jobMonitor.isHealthy();
  }

  /* 
    A rudimentary example to get the state of the jobs and scheduler.
  */
  public String getState() {
    return "Scheduler: " + schedulerMonitor.getState() + " Jobs:" + jobMonitor.getState();
  }
  
  ...
}

where is QuartzJobMonitor.java and QuartzSchedulerMonitor.java ?
