Geordi: Interactive Django profiling

Geordi is a Django middleware that lets you interactively profile your site. Add ?__geordi__ to any URL, browse to it, and you'll get a PDF showing the request's call graph and the time spent in each call.

If you've set DEBUG = True in your Django settings, anyone can profile a page–even anonymous users. With DEBUG = False, only super users can profile pages.

If you're running your Django site under a server like Gunicorn and you've configured time limits on requests, you can set GEORDI_CELERY = True to run the profiler in a background Celery task.

Installation

Before you get started, make sure you have GraphViz installed.

After you've done pip install geordi, add 'geordi' to the INSTALLED_APPS setting, and add 'geordi.VisorMiddleware' to the MIDDLEWARE_CLASSES setting. You'll probably want to put it after Django's authentication middleware and before everything else.

For background profiling with Celery, set GEORDI_CELERY = True.
