Lala is a Python library for access log analysis. It provides a set of methods to retrieve, parse and analyze access logs (only from NGINX for now), and makes it easy to plot geo-localization or time-series data. Think of it as a simpler, Python-automatable version of Google Analytics, to make reports like this:

Usage
-----
.. code:: python
from lala import WebLogs
weblogs, errored_lines = WebLogs.from_nginx_weblogs('access_logs.txt')
Similarly, to fetch logs on a distant server (for which you have access keys)
you would write:
.. code:: python
from lala import get_remote_file_content, WebLogs
logs= lala.get_remote_file_content(
host="cuba.genomefoundry.org", user='root',
filename='/var/log/nginx_cuba/access.log'
)
weblogs, errors = WebLogs.from_nginx_weblogs(logs.split('\n'))
Now ``weblogs`` is a scpecial kind of `Pandas
The web logs can therefore be analyzed using any of Pandas' built-in filtering and plotting functions. The ``WebLogs`` class also provides additional methods which are particularly useful to analyse web logs, for instance to plot pie-charts: .. code:: python ax, country_values = weblogs.plot_piechart('country_name') .. raw:: html
Next we plot the location (cities) providing the most connexions: .. code:: python ax = weblogs.plot_geo_positions() .. raw:: html
We can also restrict the entries to the UK, and plot a timeline of connexions: .. code:: python uk_entries = weblogs[weblogs.country_name == 'United Kingdom'] ax = uk_entries.plot_timeline(bins_per_day=2) .. raw:: html
Here is how to get the visitors a list of visitors and visits, sort out the most frequent visitors, find their locations, and plot it all: .. code:: python visitors = weblogs.visitors_and_visits() visitors_locations = weblogs.visitors_locations() frequent_visitors = weblogs.most_frequent_visitors(n_visitors=5) ax = weblogs.plot_most_frequent_visitors(n_visitors=5) .. raw:: html
Lala can do more, such as identifying the domain name of the visitors, which can be used to filter out the robots of search engines: .. code:: python weblogs.identify_ips_domains() filtered_entries = weblogs.filter_by_text_search( terms=['googlebot', 'spider.yandex', 'baidu', 'msnbot'], not_in='domain' ) Lala also plays nicely with the `PDF Reports
