title: uwsgi - can't see traceback in log file
body: <p>I'm using uwsgi to run a small service written in flask.</p>
  
  <p>I launch it like this:</p>
  
  <pre><code>flask/bin/uwsgi --http :9090 --master --pidfile /tmp/KVAutobus-uwsgi.pid  --processes 30 --threads 2 --wsgi-file app.py --callable app --stats :9191 --daemonize /opt/logs/KVAutobus-uwsgi.log
  </code></pre>
  
  <p>It seems to work, but I just hit a 500 error during a request and I want to see the traceback that the flask app produced but I can't find it.  Do I need different logging options?</p>
  
  <p>Here's all that's in the log file after the 500 error:</p>
  
  <pre><code>&gt;tail /opt/logs/KVAutobus-uwsgi.log
