Performance monitoring

[Kegan Gan]

Hi,

Google App Engine provides a rather extensive set of tools to monitor
the performance of your applications running in App Engine. Is there
something similar for Django?

Thanks.

Not that I know of. There's django-debug-toolbar and a quick hack I
wrote to track the time of each sql query. But I would classify both as
debugging tools. Is there anything specific you are looking for?

Thanks for reply, Andy.

I am aware of django-debug-toolbar. I am looking something to run with
production.

How do people monitor Django application performance in production
environment today?

Thanks.

Hmm I guess if I knew what you were looking for I could help more. Like
I say I've run a sql query recording tool, its v. simple. But most of
the time I rely on system tools like munin or monit.

You can always place some more performance testing code inside your views:

import time
t = time.time()
search_time=0.00
#
#place some code which hits the database here
#
search_time+=time.time()-t
search_time="%.3f"%(search_time)

This does not test the memory footprint of your application though.
Put all your db calls into a unit test sort of framework is what i did
when developing a search engine for the site im developing.

Performance monitoring doesn't have to be related to django itself.
There are external projects that cant do performance monitoring (CPU,
i/o, memory usage over time). You may give munin (http://
munin.projects.linpro.no/) a chance.

Quite so, I would suggest Zabbix (http://www.zabbix.com/) we have used it in a couple of deployments now to great success.
