Overview
========

django-app-metrics allows you to capture and report on various events in your 
applications.  You simply define various named metrics and record when they 
happen.  These might be certain events that may be immediatey useful, for 
example 'New User Signups', 'Downloads', etc. 

Or they might not prove useful until some point in the future.  But if you 
begin recording them now you'll have great data later on if you do need it. 

For example 'Total Items Sold' isn't an exciting number when you're just
launching when you only care about revenue, but being able to do a contest 
for the 1 millionth sold item in the future you'll be glad you were tracking 
it. 

You then group these individual metrics into a MetricSet, where you define
how often you want an email report being sent, and to which User(s) it should 
be sent. 

Requirements
============
celery and django-celery must be installed, however if you do not wish to 
actually use celery you can simply set CELERY_ALWAYS_EAGER = True in your 
settings and it will behave as if celery was not configured.  

Usage 
=====

  from app_metrics.utils import create_metric, metric

  # Create a new metric to track 
  my_metric = create_metric(name='New User Metric', slug='new_user_signup')

  # Create a MetricSet which ties a metric to an email schedule and sets
  # who should receive it 
  my_metric_set = create_metric_set(name='My Set', 
                                    metrics=[my_metric], 
                                    email_recipients=[user1, user2])

  # Increment the metric by one 
  metric('new_user_signup') 

  # Increment the metric by some other number 
  metric('new_user_signup', 4) 

  # Aggregate metric items into daily, weekly, monthly, and yearly totals 
  # It's fairly smart about it, so you're safe to run this as often as you
  # like 
  manage.py metrics_aggregate 

  # Send email reports to users 
  manage.py metrics_send_mail 

Backends
========

app_metrics.backends.db (Default) - This backend stores all metrics and 
aggregations in your database. NOTE: Every call to metric() generates a 
database write, which may decrease your overall performance is you go nuts 
with them or have a heavily traffic site. 

app_metrics.backends.mixpanel - This backend allows you to pipe all of your
calls to metric() to Mixpanel.com See http://mixpanel.com/api/docs/ for more
information on their API. 

Settings 
========

APP_METRICS_BACKEND - Defaults to 'app_metrics.backends.db' if not defined. 

APP_METRICS_MIXPANEL_TOKEN - Your Mixpanel.com API token 
APP_METRICS_MIXPANEL_URL - Allow overriding of the API URL end point 

TODO
====

    - Improve text and HTML templates to display trending data well 
    - Create redis backend for collection and aggregation
