APScheduler missing jobs after adding misfire_grace_time

问题

I am running a BlockingScheduler process that it's suppose to run several cron jobs, but it fails to run every single time with the message:

Run time of job "validation (trigger: cron[hour='3'], next run at: 2016-12-30 03:00:00 CST)" was missed by 0:00:02.549821

I have the following setup:

sched = BlockingScheduler(misfire_grace_time=3600, coalesce=True)
sched.add_jobstore('mongodb', collection='my_jobs')

@sched.scheduled_job('cron', hour=3, id='validation')
def validation():
    rep = Myclass()
    rep.run()

if __name__ == '__main__':
    sched.start()

I thought adding misfire_grace_time would do the trick, but every job is still missing to run.

回答1:

try adding misfire_grace_time in @sched.scheduled_job('cron', hour=3, id='validation', misfire_grace_time=3600)

回答2:

self.scheduler = BlockingScheduler(
    logger=log,
    job_defaults={'misfire_grace_time': 15*60},
)

adding the misfire_grace_time as job_defaults will work
