"Scheduler: Sending due task" log not appearing even though log level is INFO

[PaarthB]

I am using celery-redbeat==2.0.0, and it is scheduling tasks correctly at regular intervals as defined in the beat schedule. This can be confirmed as I see logs from worker process with Received task .... However, there are no corresponding logs in beat process for Scheduler: Sending due task . . . . Why is this happening? The log level for both worker and beat is set to INFO.

In fact, I see no logs from beat after this:

Configuration ->
. broker -> redis://redis:6379/0
     . loader -> celery.loaders.app.AppLoader
     . scheduler -> redbeat.schedulers.RedBeatScheduler
     . redis -> redis://redis:6379/0
        . lock -> `redbeat::lock` 25.00 minutes (1500s)
     . logfile -> [stderr]@%DEBUG
     . maxinterval -> 5.00 minutes (300s)

But I can see it is working fine, as my tasks are executed on schedule as expected. I am running both worker and beat through supervisord, but this happens if I run it directly as well.

I don't think this is specific to redbeat though, as I observe the same behaviour with PersistentScheduler default scheduler from celery as well. I recently updated to celery==5.0.5, and this wasn't happening before the update.

Having the same issue here

Hi! Just recently had to set up RedBeat and I am having the same issue. Although in my case, when I change back to the PersistentScheduler, all logs are correctly displayed again. I have tested this in celery version 5.1.2 and the most recent 5.2.0 version as well.

Is there any update regarding this issue? Thank you!

Did you by any chance customize celery's logging by using @signals.setup_logging.connect ?

Hey @jlaine , no I verified and I haven't done any such customisation. Also this would have affected all celery logs, but this only happens for celery-beat not worker (which is capturing all logs correctly)

There has been some cleanup of logging in 2.1.0. Please let me know if it helped or not.
