Project description

https://travis-ci.org/lorien/statx.png?branch=master https://img.shields.io/pypi/dm/statx.svg https://img.shields.io/pypi/v/statx.svg https://readthedocs.org/projects/statx/badge/?version=latest

What is statx library?

You might find it helpful to collect statistics about some long-running process. For insitance, web site crawling, copying big number of files, processing some big stuff. Stat class is able to:

* count things
* display speed of change
* collects things (collections are also counted)

Usage Example

>>> from statx import Stat
>>> import time
>>> import logging
>>> logging.basicConfig(level=logging.DEBUG)
>>> stat = Stat(speed_key='foo')
>>> for x in range(20):
...     stat.inc('foo')
...     stat.inc('bar', 2)
...     stat.collect('gaz', 13)
...     time.sleep(0.5)
...
