Linux Server See the Historical and Statistical Uptime of System With tuptime Utility

You can use the following tools to see how long system has been running on a Linux or Unix-like system:

  • uptime : Tell how long the server has been running.
  • lastt : Show the reboot and shutdown time.
  • tuptime : Report the historical and statistical running time of system, keeping it between restarts. Like uptime command but with more interesting output.

Finding out the system last reboot time and date

You can use the following commands to get the last reboot and shutdown time and date on a Linux operating system (also works on OSX/Unix-like system):

 ## 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

Sample outputs:

Say hello to tuptime

The tuptime command line tool can report the following information on a Linux based system:

  1. Count system startups
  2. Register first boot time (a.k.a. installation time)
  3. Count nicely and accidentally shutdowns
  4. Average uptime and downtime
  5. Current uptime
  6. Uptime and downtime rate since first boot time
  7. Accumulated system uptime, downtime and total
  8. Report each startup, uptime, shutdown and downtime

Installation

Type the following command to clone a git repo on a Linux operating system:
$ cd /tmp
$ git clone https://github.com/rfrail3/tuptime.git
$ ls
$ cd tuptime
$ ls

Sample outputs:

Make sure you’ve Python v2.7 installed with sys, optparse, os, re, string, sqlite3, datetime, disutils, and locale modules.
You can simply install it as follows:
$ sudo tuptime-install.sh
OR do a manual installation (recommended method due to systemd or non-systemd based Linux system):
$ sudo cp /tmp/tuptime/latest/cron.d/tuptime /etc/cron.d/tuptime
If is a system with systemd, copy service file and enable it:
$ sudo cp /tmp/tuptime/latest/systemd/tuptime.service /lib/systemd/system/
$ sudo systemctl enable tuptime.service

If the systemd don’t have systemd, copy init file:
$ sudo cp /tmp/tuptime/latest/init.d/tuptime.init.d-debian7 /etc/init.d/tuptime
$ sudo update-rc.d tuptime defaults

Run it

Simply type the following command:
$ sudo tuptime
Sample outputs:

After kernel upgrade I rebooted the box and typed the same command again:

 $   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

You can change date and time format as follows:
$ sudo tuptime -d '%H:%M:%S %m-%d-%Y'
Sample outputs:

 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

Enumerate each startup, uptime, shutdown and downtime:
$ sudo tuptime -e
Sample outputs:

 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
