analytics 0.3.0

Library for efficiently adding analytics to your project.

Py-Analytics is a library designed to make it easy to provide analytics as part of any project.

The project’s goal is to make it easy to store and retrieve analytics data. It does not provide any means to visualize this data.

Currently, only Redis is supported for storing data.

Requirements

Required

Requirements should be handled by setuptools, but if they are not, you will need the following Python packages:

• nydus

• redis

• dateutil

Optional

• hiredis

analytics.create_analytic_backend

Creates an analytics object that allows to to store and retrieve metrics:

>>> from analytics import create_analytic_backend
>>>
>>> analytics = create_analytic_backend({
>>>     'backend': 'analytics.backends.redis.Redis',
>>>     'settings': {
>>>         'defaults': {
>>>             'host': 'localhost',
>>>             'port': 6379,
>>>             'db': 0,
>>>         },
>>>         'hosts': [{'db': 0}, {'db': 1}, {'host': 'redis.example.org'}]
>>>     },
>>> })

Internally, the Redis analytics backend uses nydus to distribute your metrics data over your cluster of redis instances.

There are two required arguements:

• backend: full path to the backend class, which should extend analytics.backends.base.BaseAnalyticsBackend

• settings: settings required to initialize the backend. For the Redis backend, this is a list of hosts in your redis cluster.

Example Usage

from analytics import create_analytic_backend
import datetime

analytics = create_analytic_backend({
    "backend": "analytics.backends.redis.Redis",
    "settings": {
        "hosts": [{"db": 5}]
    },
})

year_ago = datetime.date.today() - datetime.timedelta(days=265)

#create some analytics data
analytics.track_metric("user:1234", "comment", year_ago)
analytics.track_metric("user:1234", "comment", year_ago, inc_amt=3)

#retrieve analytics data:
analytics.get_metric_by_day("user:1234", "comment", year_ago, limit=20)
analytics.get_metric_by_week("user:1234", "comment", year_ago, limit=10)
analytics.get_metric_by_month("user:1234", "comment", year_ago, limit=6)

#create a counter
analytics.track_count("user:1245", "login")
analytics.track_count("user:1245", "login", inc_amt=3)

#retrieve multiple metrics at the same time
#group_by is one of ``month``, ``week`` or ``day``
analytics.get_metrics([("user:1234", "login",), ("user:4567", "login",)], year_ago, group_by="day")
>> [....]

#retrieve a count
analytics.get_count("user:1245", "login")

#retrieve counts
analytics.get_counts([("user:1245", "login",), ("user:1245", "logout",)])

TODO

• Add more backends (riak, …)?

• Add an API so it can be deployed as a stand alone service (http, protocolbuffers, …)
