  org.quartz.plugins.history.LoggingTriggerHistoryPlugin

All Implemented Interfaces:

SchedulerPlugin, TriggerListener

public class LoggingTriggerHistoryPlugin
extends Object
implements SchedulerPlugin, TriggerListener

Logs a history of all trigger firings via the Jakarta Commons-Logging framework.

The logged message is customizable by setting one of the following message properties to a String that conforms to the syntax of java.util.MessageFormat.

TriggerFiredMessage - available message data are:

Element	Data Type	Description
0	String	The Trigger's Name.
1	String	The Trigger's Group.
2	Date	The scheduled fire time.
3	Date	The next scheduled fire time.
4	Date	The actual fire time.
5	String	The Job's name.
6	String	The Job's group.
7	Integer	The re-fire count from the JobExecutionContext.

The default message text is "Trigger {1}.{0} fired job {6}.{5} at: {4, date, HH:mm:ss MM/dd/yyyy}"

TriggerMisfiredMessage - available message data are:

Element	Data Type	Description
0	String	The Trigger's Name.
1	String	The Trigger's Group.
2	Date	The scheduled fire time.
3	Date	The next scheduled fire time.
4	Date	The actual fire time. (the time the misfire was detected/handled)
5	String	The Job's name.
6	String	The Job's group.

The default message text is "Trigger {1}.{0} misfired job {6}.{5} at: {4, date, HH:mm:ss MM/dd/yyyy}. Should have fired at: {3, date, HH:mm:ss MM/dd/yyyy}"

TriggerCompleteMessage - available message data are:

Element	Data Type	Description
0	String	The Trigger's Name.
1	String	The Trigger's Group.
2	Date	The scheduled fire time.
3	Date	The next scheduled fire time.
4	Date	The job completion time.
5	String	The Job's name.
6	String	The Job's group.
7	Integer	The re-fire count from the JobExecutionContext.
8	Integer	The trigger's resulting instruction code.
9	String	A human-readable translation of the trigger's resulting instruction code.

The default message text is "Trigger {1}.{0} completed firing job {6}.{5} at {4, date, HH:mm:ss MM/dd/yyyy} with resulting trigger instruction code: {9}"

Parameters:

triggerCompleteMessage - String in java.text.MessageFormat syntax.

setTriggerFiredMessage

public void setTriggerFiredMessage(String triggerFiredMessage)

Set the message that is printed upon a trigger's firing.

Parameters:

triggerFiredMessage - String in java.text.MessageFormat syntax.

initialize

public void initialize(String pname,
                       Scheduler scheduler,
                       ClassLoadHelper classLoadHelper)
                throws SchedulerException

Called during creation of the Scheduler in order to give the SchedulerPlugin a chance to initialize.

Specified by:

initialize in interface SchedulerPlugin

Parameters:

pname - The name by which the plugin is identified.

scheduler - The scheduler to which the plugin is registered.

classLoadHelper - The classLoadHelper the SchedulerFactory is actually using

Throws:

SchedulerConfigException - if there is an error initializing.

SchedulerConfigException - if there is an error initializing.

SchedulerException

start

public void start()

Description copied from interface: SchedulerPlugin

Called when the associated Scheduler is started, in order to let the plug-in know it can now make calls into the scheduler if it needs to.

Specified by:

start in interface SchedulerPlugin

shutdown

public void shutdown()

Called in order to inform the SchedulerPlugin that it should free up all of it's resources because the scheduler is shutting down.

Specified by:

shutdown in interface SchedulerPlugin

getName

public String getName()

Description copied from interface: TriggerListener

Get the name of the TriggerListener.

Specified by:

getName in interface TriggerListener

triggerFired

public void triggerFired(Trigger trigger,
                         JobExecutionContext context)

Description copied from interface: TriggerListener

Called by the Scheduler when a Trigger has fired, and it's associated JobDetail is about to be executed.

It is called before the vetoJobExecution(..) method of this interface.

Specified by:

triggerFired in interface TriggerListener

Parameters:

trigger - The Trigger that has fired.

context - The JobExecutionContext that will be passed to the Job'sexecute(xx) method.

triggerMisfired

public void triggerMisfired(Trigger trigger)

Description copied from interface: TriggerListener

Called by the Scheduler when a Trigger has misfired.

Consideration should be given to how much time is spent in this method, as it will affect all triggers that are misfiring. If you have lots of triggers misfiring at once, it could be an issue it this method does a lot.

Specified by:

triggerMisfired in interface TriggerListener

Parameters:

trigger - The Trigger that has misfired.

triggerComplete

public void triggerComplete(Trigger trigger,
                            JobExecutionContext context,
                            Trigger.CompletedExecutionInstruction triggerInstructionCode)

Description copied from interface: TriggerListener

Called by the Scheduler when a Trigger has fired, it's associated JobDetail has been executed, and it's triggered(xx) method has been called.

Specified by:

triggerComplete in interface TriggerListener

Parameters:

trigger - The Trigger that was fired.

context - The JobExecutionContext that was passed to the Job'sexecute(xx) method.

triggerInstructionCode - the result of the call on the Trigger'striggered(xx) method.

vetoJobExecution

public boolean vetoJobExecution(Trigger trigger,
                                JobExecutionContext context)

Description copied from interface: TriggerListener

Called by the Scheduler when a Trigger has fired, and it's associated JobDetail is about to be executed. If the implementation vetos the execution (via returning true), the job's execute method will not be called.

It is called after the triggerFired(..) method of this interface.

Specified by:

vetoJobExecution in interface TriggerListener

Parameters:

trigger - The Trigger that has fired.

context - The JobExecutionContext that will be passed to the Job'sexecute(xx) method.
