Quartz: Get all triggers

 

List<String> triggerGroupNames = scheduler.getTriggerGroupNames();
for (String groupName : triggerGroupNames) {
	for (TriggerKey triggerKey : scheduler.getTriggerKeys(GroupMatcher.triggerGroupEquals(groupName))) {
		String triggerName = triggerKey.getName();
		String triggerGroup = triggerKey.getGroup();

		Trigger trigger = scheduler.getTrigger(triggerKey);
		Date nextFireTime = trigger.getNextFireTime();

		System.out.println("triggerName : " + triggerName + " triggerGroup : " + triggerGroup + " - " + nextFireTime);

	}

}

Output

jobName : My_Timer_Job groupName : My_Timer_Job_Group - Thu Mar 04 15:14:54 IST 2021 triggerName : Trigger1 triggerGroup : DEFAULT - Thu Mar 04 15:14:54 IST 2021
