I configure django to send me 500 error via email and gets some mail with:
Traceback (most recent call last):

  File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py", line 115, in get_response
    response = callback(request, *callback_args, **callback_kwargs)

  File "/var/www/webvirtmgr/overview/views.py", line 27, in cpuusage
    return HttpResponse(cpu_usage)

UnboundLocalError: local variable 'cpu_usage' referenced before assignment
