In 2005, Novell reported a server with a 6 year uptime.[2][3]
Netcraft maintains the uptime records for many thousands of web hosting computers.[4]

| Using systeminfo | |
| 4>
Users of Windows XP Professional, Windows Server 2003 and Windows Vista systems can type systeminfo at the Command Prompt to display all system information, including the System Up Time.[5]
C:\> systeminfo | find "Time:"
System Up Time: 0 Days, 8 Hours, 7 Minutes, 19 Seconds
Note: Windows Vista Business 64-bit and Windows 7 do not return a "System Up Time" but "System Boot Time" instead. Also note that the exact text and date format is dependent of the language and locale, Windows is running.

| Using net statistics server/workstation | |
| 4>
C:\> net statistics workstation | find "since"
Server Statistics for \\COMPUTERNAME
Statistics since 8/31/2009 8:52:29 PM
The line that start with "Statistics since ..." provides the time that the server was up from. The command "net stats srv" is shorthand for "net statistics server."[6] The exact text and date format is dependent of the language and locale, Windows is running.

| Using Uptime.exe | |
| 4>
Microsoft has also provided a downloadable Uptime.exe utility:
C:\> Uptime
SYSTEMNAME has been up for: 2 day(s), 4 hour(s), 24 minute(s), 47 second(s)

| Using WMI | |
| 4>
Uptime can also be determined via Windows Management Instrumentation from the command-line with WMIC:
C:\> wmic os get lastbootuptime
LastBootUpTime
20110508161751.822066+060
The timestamp is in the format yyyymmddhhmmss.nnn, so this is a computer that last booted up on 8 May 2011 at 16:17:51.822. WMI can also be used to find the boot time of remote computers as well (Windows permissions allowing), for example with WMIC:
C:\> wmic /node:"my-server" os get lastbootuptime
LastBootUpTime
20101219141712.462006+060
The text "LastBootUpTime" and the timestamp format are always the same regardless of the language and locale, Windows is running.
WMI can also be used via a programming language such as VBScript or Powershell[7][8]

Windows 7 Task Manager Performance tab screenshot.
Users of Windows Vista and Windows 7 can see uptime in Windows Task Manager under the tab Performance.

| Using uptime | |
| 4>
Users of Linux systems can use the uptime utility (uptime(1) – Linux User Commands Manual) to get the uptime, together with the current time, the number of users and load averages for the past 1, 5 and 15 minute intervals:
$ uptime
18:17:07 up 68 days, 3:57, 6 users, load average: 0.16, 0.07, 0.06
[edit] Tags:Linux,Manual, | |
| Using /proc/uptime | |
| 4>
Shows how long the system has been on since it was last restarted:
$ cat /proc/uptime
350735.47 234388.90
The first number is the total number of seconds the system has been up. The second number is how much of that time the machine has spent idle, in seconds.[9] On multi core systems (and some linux versions) the second number is the sum of the idle time accumulated by each CPU.[10]

| Using uptime | |
| 4>
Like Linux, BSD based operating systems such as FreeBSD and Mac OS X also have the uptime command (See uptime(1) – FreeBSD General Commands Manual).
[edit] Tags:Operating System,Bsd,Freebsd, | |
| Using sysctl | |
| 4>
There is also a method of using sysctl to call the system's last boot time[11]:
$ sysctl kern.boottime
kern.boottime: { sec = 1271934886, usec = 667779 } Thu Apr 22 12:14:46 2010

| OpenVMS | |
| 3>
Users of OpenVMS systems can type show system at the command prompt.[12]
$ show system/noprocess
OpenVMS V7.3-2 on node JACK 29-JAN-2008 16:32:04.67 Uptime 894 22:28:52
This shows the uptime as days then hours:minutes:seconds.

| External Uptime Measuring | |
| 2>
There are a many external services which can be used to monitor the uptime and downtime as well as availability of a service or a host. Some examples:
Pingdom
WatchMouse[13][14]
