系统管理员的重要部分是监视和检查Linux系统已经走了很长时间。保持跟踪Linux系统的时间以优化系统资产是一个正确的概念。本文介绍了Tuptime工具，该工具 可以帮助系统管理员了解Linux计算机的启动和运行时间。
Tuptime工具用于报告Linux系统的历史和统计运行时间（正常运行时间），并在两次重新启动之间进行跟踪。
注册第一次启动时间
跟踪系统启动
计算系统关闭次数
计算正常运行时间和停机时间
计算最大，平均，低正常运行时间和停机时间
打印当前的正常运行时间
要安装Tuptime工具，应满足以下预安装要求
建立了Python 2.7或3.X，但建议使用最新版本。
Python模块（sys，os，optparse，sqlite3，datetime，locale，平台，子进程，时间）。
Linux操作系统
要在Linux上找到已安装的python，请使用以下命令-
$ apt-cache search python | egrep "^python2.[0-9] " --color
