django-processinfo is a Django application to collect information about the running server processes.
Project description
django-processinfo is a reuseable Django application for collecing information about the running server processes. We try to cause as little additional overhead: django-processinfo creates most of the time only one database query to update the data.
The most important data that django-processinfo will be captured:
Process statistics:
process PID, start time, life times
Number of average/max living processes
min/average/max response times
Total request/exceptions count
Memory statistics:
min/average/max memory usage (VmRSS, VmPeak)
System informations:
System memory usage
Swap usage
load average
django-processinfo splits some of these data per SITE_ID, so you can see e.g. which site is mostly used.
What is it not:
track user actions
collect infos which are found in e.g. apache.log
Its not a sourcecode profiler (read https://code.djangoproject.com/wiki/ProfilingDjango)

limitation
This only works, if /proc/$$/status exists. So only on unix/linux like platforms, yet.
screenshots
Here some screenshots (from v0.2 - 19.08.2011) how it looks like:
install
install it e.g.:
pip install django-processinfo
add settings (see below)
create tables (run syncdb)
settings
add this to your settings.py:
import os
import django_processinfo
INSTALLED_APPS = (
...
'django_processinfo',
...
)
MIDDLEWARE_CLASSES = (
'django_processinfo.middlewares.django_processinfo.ProcessInfoMiddleware',
...
)
# Put templates above admin contrib, e.g.:
TEMPLATE_DIRS = (
...
os.path.join(os.path.abspath(os.path.dirname(django_processinfo.__file__)), "templates/"),
...
)
# include app settings from ./django_processinfo/app_settings.py
from django_processinfo import app_settings as PROCESSINFO
# Change settings like this:
PROCESSINFO.ADD_INFO = True
ProcessInfoMiddleware
The ProcessInfoMiddleware can actually be inserted anywhere. However, it should be added far above. Thus, to capture everything.
For performance enhancement, you can put ProcessInfoMiddleware after LocalSyncCacheMiddleware. But then, however, lacks statistical values on every cache hit!
app settings
Available django-processinfo settings can you found in ./django_processinfo/app_settings.py
