title: Send log messages from all celery tasks to a single file
body: <p>I'm wondering how to setup a more specific logging system. All my tasks use</p>
  
  <pre><code>logger = logging.getLogger(__name__)
  </code></pre>
  
  <p>as a module-wide logger.</p>
  
  <p>I want celery to log to "celeryd.log" and my tasks to "tasks.log" but I got no idea how to get this working. Using <code>CELERYD_LOG_FILE</code> from django-celery I can route all celeryd related log messages to celeryd.log but there is no trace of the log messages created in my tasks.</p>
