From: http://chris-lamb.co.uk/projects/django-dumpslow/

django-dumpslow is a reusable Django application that logs requests that take a
long time to execute and provides an tool to summarise the resulting data.

Modelled on mysqldumpslow, django-dumpslow is intended as a tool to determine
which parts of a project might benefit most from optimisation and to provide
valuable empirical data.

The tool groups requests that are similar by exploiting Django's ability to
reverse URLs - requests that that use the same view should not counted
distinctly. Views can then be grouped by the total accumulated time spent by
that view or simply by their raw frequency in the logs.

Additionally, if the log entries contain timestamps then django-dumpslow can
limit queries by a user-defined interval. This can be useful for generating
regular reports of slow pages, perhaps by regularly emailing them to a
development list.

Data is stored in Redis to allow easy collation of data from multiple front-end
servers (django-dumpslow requires the Redis Python client library).

An example output is:

  $ ./manage.py dumpslow
  View                                Accumulated time
  =====================================================
  example.views.slow                             92.88
  /unknown (unreversible url)                    16.84

django-dumpslow ships with an example project that demonstrates its
functionality.
