使用 tuptime 工具查看 Linux 服务器系统的开机时间的历史和统计
你可以使用下面的工具来查看 Linux 或类 Unix 系统运行了多长时间:
- uptime : 告诉你服务器运行了多长的时间。
- lastt : 显示重启和关机时间。
- tuptime : 报告系统的运行时间历史和运行时间统计,这是指重启之间的运行时间。和 uptime 命令类似,不过输出结果更有意思。
找出系统上次重启时间和日期
你可以使用下面的命令来获取Linux操作系统的上次重启和关机时间及日期(在OSX/类Unix系统上也可以用):
### 显示系统重启和关机时间
who -b
last reboot
last shutdown
### 开机信息
uptime
cat /proc/uptime
awk '{ print "up " $1 /60 " minutes"}' /proc/uptime
w
样例输出:

跟 tuptime 问打个招呼吧
tuptime 命令行工具可以报告基于 Linux 的系统上的下列信息:
- 系统启动次数统计
- 注册首次启动时间(也就是安装时间)
- 正常关机和意外关机统计
- 平均开机时间和故障停机时间
- 当前开机时间
- 首次启动以来的开机和故障停机率
- 累积系统开机时间、故障停机时间和合计
- 报告每次启动、开机时间、关机和故障停机时间
安装
$ cd /tmp
$ git clone https://github.com/rfrail3/tuptime.git
$ ls
$ cd tuptime
$ ls
样例输出:

确保你安装了带有 sys,optparse,os,re,string,sqlite3,datetime,disutils 和 locale 模块的 Python v2.7。
你可以像下面这样来安装:
$ sudo tuptime-install.sh
或者,可以手工安装(基于 systemd 或非 systemd ):
$ sudo cp /tmp/tuptime/latest/cron.d/tuptime /etc/cron.d/tuptime
如果系统是systemd的,拷贝服务文件并启用:
$ sudo cp /tmp/tuptime/latest/systemd/tuptime.service /lib/systemd/system/
$ sudo systemctl enable tuptime.service
如果系统不是systemd的,拷贝初始化文件:
$ sudo cp /tmp/tuptime/latest/init.d/tuptime.init.d-debian7 /etc/init.d/tuptime
$ sudo update-rc.d tuptime defaults
运行
只需输入以下命令:
$ sudo tuptime
样例输出:

在一次更新内核后,我重启了系统,然后再次输入了同样的命令:
$ sudo tuptime
