munhitsu / django-dowser

Django fork of amazing memory leaks tracking application for python wsgi - the Dowser

About

Based on: Dowser

A Django specific Dowser port.

Following enhancements have been implemented on top of the original Dowser:

• long term historical analysis: 1m, 1h, 1d, 4w buffers
• optimization by moving from lists to python deque
• server load optimization by moving charts to google chart
• only superuser can view the analysis (Django specific)

Screen shot

Future

• move charts to javascript
• move inline html to templates
• drop Django 1.x and Python 2.x compatibility

Installation

# latest release
pip install django-dowser
# or latest master
pip install git+git://github.com/munhitsu/django-dowser.git

Next, modify project configuration.

settings.py

INSTALLED_APPS += ['django_dowser']

urls.py

from django.urls import path, include
urlpatterns += [url(r'^dowser/', include('django_dowser.urls'))]

Note

Use django-dowser only on multithreaded/gevent servers. With forking, or multiple servers, each process will have it's own Dowser storage, so you will only get a glimpse into one process and further requests may be load balanced to the other servers.

Usage

Start the project and open link:

http://domain/dowser/

When running in the local development mode, it is usually:

http://127.0.0.1:8000/dowser/

django-dowser's Issues

Django 1.9 - 'WSGIRequest' object has no attribute 'REQUEST'

When running dowser on Django 1.9.5 I get:

Traceback (most recent call last):
File "C:\Python27\lib\site-packages\django\core\handlers\base.py", line 147, in get_response
response = wrapped_callback(request, _callback_args, *_callback_kwargs)
File "C:\Python27\lib\site-packages\django\contrib\auth\decorators.py", line 23, in _wrapped_view
return view_func(request, _args, *_kwargs)
File "C:\Python27\lib\site-packages\django_dowser\views.py", line 16, in index
floor = request.REQUEST.get('floor', 0)
AttributeError: 'WSGIRequest' object has no attribute 'REQUEST'

According to Django release notes see link
The WSGIRequest.REQUEST property is removed.

reverse import need shim for newer Django versions

Error viewing trace

Not sure if this is dowser, or something on my end, but I'm getting an error when click trace: IOError: sys.stdout access restricted by mod_wsgi

SystemError: Objects/tupleobject.c:118: bad argument to internal function

After we installed django-dowser, we started to get strange errors:

Traceback (most recent call last):
  File "... site-packages/django/core/handlers/wsgi.py", line 
    from django.conf import settings
SystemError: Objects/tupleobject.c:118: bad argument to internal function

On devserver seems like everything is working fine, but when we use uwsgi - we get such error.

This error occurs after a second request to any page.

Not working in Django 1.3 because of bad import

django_dowser/urls.py:

name 'patterns' is not defined

This happens because of bad import: from django.conf.urls import * works without error but does not import patterns because it is in django.conf.urls.defaults.

Tested on django 1.3.7

dowser not showing values

locally its working but on server its not showing values.

Project still maintained?

Hi,

I'd like to know if this project is still being maintained; if so, I'd like to make it compatible with Python 3 (currently it's not, it uses Python 2 functions like iteritems or similar). Otherwise I'll fork it and release it with a different name, for Python 3 support.

Thanks!

redirection to the admin

Hi and thanks for the very nice project, I was trying to use it though but no luck so far, using Django 1.4.13.

I followed the instructions but every time I go to
http://localhost:8000/dowser/

my browser redirects automatically to (even after I'm logged in as admin):

http://localhost:8000/adminiu0Roojo/?next=/dowser/

I've also seen an error once

Traceback (most recent call last):

    typename = objtype.__module__ + "." + objtype.__name__
TypeError: unsupported operand type(s) for +: 'property' and 'str'

Which I guess depends on some unhandled type and I thought that this was the issue maybe, it still doesn't work even if I handle the exception.

Any ideas? Thanks

getting error django-dowser 0.1.3

unsupported operand type(s) for +: 'property' and 'str'

AttributeError: module 'sys' has no attribute 'getcheckinterval'. Did you mean: 'getswitchinterval'?

When trying to add urlpatterns += [url(r"^rest/dowser/", include("django_dowser.urls"))] , the following error occurs:

I'm using Python 3.10 and it seems that sys.getcheckinterval was removed since Python 3.9

Release a new version on PyPI

The current PyPI version (0.1.4) is failing on recent Django versions. Would it be possible to make a release to fix that?
