statx 0.0.2

什么是statx库？

您可能会发现收集有关某些长时间运行过程（例如网站爬取、复制大量文件、处理某些大型数据）的统计信息很有用。Stat类能够

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

使用示例

>>> 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)
...

                                    13, 13]})
