Celery logs on Heroku

I deployed a Celery app on Heroku, but I don't see any task related information in Heroku log (I know that tasks are actually executed). As far as I know Heroku automatically collects everything that was logged to stdout or stderr. Does Celery not log to stdout/stderr by default? Or do I need need to implement custom logging? I would expect to at least see something like "executing task X" in the logs.

If your celery workers are issuing print statements or using the standard python logging classes, then you should see something that looks like this in your heroku logs:

2015-04-25T00:25:00.072929+00:00 app[celeryd.1]: [2015-04-25 00:25:00,072: INFO/Beat] Scheduler: Sending due task contest-winner (app.contest_win)

celeryd will be replaced by whatever you named the celery worker in your ProcFile. Mine looks like this and you can see the process label in the logging statement above:

celeryd: celery -A app.celery worker -E -B --loglevel=INFO

Of course, you have to set the log level too :).
