• Visit http://cup.iobusy.com for more details
  • 访问 http://cup.iobusy.com 获取更多信息
• **From now (Version 3.3.1) on, CUP will only support Python3 **
  • If you want use cup in Python2.7.x, plz install it with version < 3.3
    • e.g. # python -m pip install cup==3.2.31
    • cup 3.2.X versions will only maintain bug fixes for Python2. Will not add any new features.
    • If you want to try new features, pls use cup under Python3.
  • If you use cup under Python3, pls refer to the Installation part.
  • 从 3.3.1 版本开始，Cup 新版本只对 Python3提供支持。如果你想继续在python2.7中使用它，请使用3.2.X版本。
  • 后续 3.2.X版本对继续提供对Python2.7的bug fix 支持，但不会再增加新的功能。
  • 推荐大家在Python3中使用Cup

# Examples:
# 1. Get system info
import cup
# count cpu usage in interval, by default 60 seconds
from cup.res import linux
cpuinfo = linux.get_cpu_usage(intvl_in_sec=60)
print cpuinfo.usr

# total, available, percent, used, free, active, inactive, buffers, cached
from cup.res import linux
meminfo = linux.get_meminfo()
print meminfo.total
print meminfo.available

Tests

- Install python-nose before running the tests
- run `cd ./cup_tests; nosetests -s`
