The use of the spooler_process_before() or spooler_process_after() function in the monitor script defines whether a Monitor is a pre-processor or post-processor.
In addition to the two spooler_process_... functions two further functions can be used in monitor scripts:
spooler_task_before()
spooler_task_after()
The most important difference between the spooler_process and spooler_task functions is that the spooler_task functions are able to handle return codes.
More detailed information about these functions can be found in the Monitors section of the JobScheduler reference documentation.
