django-memcache-status 2.2

A django application that displays the load and other statistics about your memcached instances in the admin.

---

django-memcache-status

This app displays the current load and some statistics for your memcached instances in the index view of your Django admin section.

Currently these memcached bindings are tested:

Backend	Support
python-memcached with vanilla Django	✅ Works fine with >= v1.57
pylibmc with django-pylibmc	✅ Works fine
pymemcache with django-pymemcache	❎ Does not provide stats

Other bindings may provide statistics too.

Installation

First add memcache_status to your INSTALLED_APPS list.

INSTALLED_APPS = [
    # ...
    'memcache_status',
]

Then you have two options:

1. The quickest way is to replace your Django Admin index page with the one provided by django-memcache-status. This will show the memcache stats in the top left column. This was the regular behavior of django-memcache-status prior to version 2.0.

   Place this in any admin.py file of your project:

   from django.contrib import admin
   admin.site.index_template = 'memcache_status/admin_index.html'

2. If you need to manually place the stats, simply add the CSS file and include the memcache-status template anywhere you like:

   <link rel="stylesheet" href="{% static "memcache_status.css" %}"/>
   {% include "memcache_status/memcache_status.html" %}

Local Development

Install the package using Pipenv and run the tests:

$ pipenv install --dev
$ pipenv run test

You can test against a matrix of Python and Django versions using tox:

$ tox

Once run you will see a coverage report in /tmp/coverage_report/django-memcache-status.

You can run a local runserver with the test application to see the admin:

$ pipenv run django-admin.py migrate
$ pipenv run django-admin.py createsuperuser
$ pipenv run django-admin.py runserver

To test a specific cache backend define it in the env variable:

$ TEST_CACHE_BACKEND=django-pylibmc pipenv run django-admin.py runserver

Note

If you’re testing pylibmc on OS X and you get an error like 'libmemcached/memcached.h' file not found, install pylibmc manually, then run the installation again:

$ brew install libmemcached
$ pipenv run pip install pylibmc --install-option="--with-libmemcached=/usr/local/Cellar/libmemcached/1.0.18_2/"
$ pipenv install --dev
