Adding Jobs ¶ Jobs can be added to the scheduler when the app starts They are created in decorated functions, which should be imported before apprun () is called # interval example @schedulertask('interval', id='do_job_1', seconds=30, misfire_grace_time=900) def job1() print('Job 1 executed') # cron examples @schedulertask('cron', id='do_job_2', minute='*') def job2() print('Job 2 executed') @schedulertask('cronWe created Cronitor because cron itself can't alert you if your jobs fail or never start Cronitor is easy to integrate and provides you with instant alerts when things go wrong Learn more about cron job monitoringFlaskapscheduler background Frequently Asked Questions, from apschedulerschedulersbackground import BackgroundScheduler def myjob() which ma

Understanding WPCron Scheduling Unlike a traditional system cron that schedules tasks for specific times (eg "every hour at 5 minutes past the hour"), WPCron uses intervals to simulate a system cron WPCron is given two arguments the time for the first task, and an interval (in seconds) after which the task should be repeatedAll groups and messages It takes quite a few arguments, first of them being function to be ran Next is the trigger type, which can be interval, cron or date Interval schedules jobs to run periodically in said interval Cron is just good old cronlike scheduler, which allows for classic and keyword argumentbased scheduling arguments
