[FEATURE REQUEST] Periodic Tasks support customize cron logger

[yxlimo]

i want to customize cron logger to get more info, but i can't do it with scheduler

return &Scheduler{
  cron:       cron.New(cron.WithLocation(loc)),
}

maybe we can add an option for schedulerOpts like

struct {
    CronLogger cron.Logger
    Logger Logger
    LogLevel LogLevel
}

or just use asynq logger wrapper, seems little strange, and it need to do many things to handle edge case.

type cronLoggerWrapper struct {
       logger Logger
}

func (l *cronLoggerWrapper) Info(msg string, keysAndValues ...interface{}) {
       l.logger.Info(msg, )
}

WDYT?

@yxlimo Thank you for opening an issue! What kind of logs do you need?

thank you for reply，i need logs like this

• every time cronjob started
• enqueue task success or failed

every time cronjob started

You can do this within your Handler code. If it's shared between multiple task types, I'd recommend using MiddlewareFunc to have that applied to multiple tasks. See this wiki page for examples.

enqueue task success or failed

Currently, you can provide SchedulerOpts.EnqueueErrorHandler but there's an open feature request to add callbacks to both before and after the enqueue event #456; And probably this feature will be available pretty soon

Closing this since it can be achieved using pre and post enqueue callbacks added in #476
