使用tuptime工具查看Linux服务器系统历史开机时间统计

你们可以使用下面的工具来查看Linux或者类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 : 报告系统的历史运行时间和统计运行时间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

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

## Just show  system reboot and shutdown date and time ###
who -b
last reboot
last shutdown
## Uptime info ##
uptime
cat /proc/uptime
awk '{ print "up " $1 /60 " minutes"}' /proc/uptime
w

样例输出:

图像01用于找出服务器开机时间的多个Linux命令

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

  1. 系统启动次数统计
  2. 注册首次启动时间(也就是安装时间)
  3. 正常关机和意外关机统计
  4. 平均开机时间和故障停机时间
  5. 当前开机时间
  6. 首次启动以来的开机和故障停机率
  7. 累积系统开机时间、故障停机时间和合计
  8. 报告每次启动、开机时间、关机和故障停机时间

安装

输入下面的命令来克隆git仓库到Linux系统中

$ cd /tmp
$ git clone https://github.com/rfrail3/tuptime.git
$ ls
$ cd tuptime
$ ls

样例输出:

图像02克隆git仓库

确保你随sysoptparseosrestringsqlite3datetimedisutils安装了Python v2.7和本地模块。

你可以像下面这样来安装:

$ sudo tuptime-install.sh

或者可以手工安装根据基于systemd或非systemd的Linux的推荐方法

$ 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:

图像03tuptime工作中

在更新内核后,我重启了系统,然后再次输入了同样的命令:

$ sudo tuptime
System startups:	2   since   03:52:16 PM 08/21/2015
System shutdowns:	1 ok   -   0 bad
Average uptime: 	7 days, 16 hours, 48 minutes and 3 seconds
Average downtime: 	2 hours, 30 minutes and 5 seconds
Current uptime: 	5 minutes and 28 seconds   since   06:23:06 AM 09/06/2015
Uptime rate: 		98.66 %
Downtime rate: 		1.34 %
System uptime: 		15 days, 9 hours, 36 minutes and 7 seconds
System downtime: 	5 hours, 0 minutes and 11 seconds
System life: 		15 days, 14 hours, 36 minutes and 18 seconds

你可以像下面这样修改日期和时间格式:

$ sudo tuptime -d '%H:%M:%S %m-%d-%Y'

样例输出:

System startups:	1   since   15:52:16 08-21-2015
System shutdowns:	0 ok   -   0 bad
Average uptime: 	15 days, 9 hours, 21 minutes and 19 seconds
Average downtime: 	0 seconds
Current uptime: 	15 days, 9 hours, 21 minutes and 19 seconds   since   15:52:16 08-21-2015
Uptime rate: 		100.0 %
Downtime rate: 		0.0 %
System uptime: 		15 days, 9 hours, 21 minutes and 19 seconds
System downtime: 	0 seconds
System life: 		15 days, 9 hours, 21 minutes and 19 seconds

计算每次启动、开机时间、关机和故障停机时间:

$ sudo tuptime -e

样例输出:

Startup:  1  at  03:52:16 PM 08/21/2015
Uptime:   15 days, 9 hours, 22 minutes and 33 seconds
 
System startups:	1   since   03:52:16 PM 08/21/2015
System shutdowns:	0 ok   -   0 bad
Average uptime: 	15 days, 9 hours, 22 minutes and 33 seconds
Average downtime: 	0 seconds
Current uptime: 	15 days, 9 hours, 22 minutes and 33 seconds   since   03:52:16 PM 08/21/2015
Uptime rate: 		100.0 %
Downtime rate: 		0.0 %
System uptime: 		15 days, 9 hours, 22 minutes and 33 seconds
System downtime: 	0 seconds
System life: 		15 days, 9 hours, 22 minutes and 33 seconds
