The “last reboot time” of a computer or server refers to the point in time when it was last restarted. It is an important piece of information that can be used to troubleshoot problems, track system uptime, and ensure that the system is running smoothly.
There are several ways to check the last reboot time on a computer or server. One common method is to use the command prompt. On Windows systems, you can open the command prompt by typing “cmd” into the search bar and pressing enter. Once the command prompt is open, you can type the following command:
systeminfo | findstr /C:"System Boot Time"
This command will display the system boot time, which is the same as the last reboot time.
Another method for checking the last reboot time is to use the Windows Event Viewer. The Event Viewer is a tool that allows you to view a history of events that have occurred on your computer. To open the Event Viewer, click on the Start menu and type “eventvwr” into the search bar. Once the Event Viewer is open, navigate to the “Windows Logs” section and then click on the “System” log. In the System log, you will see a list of all the events that have occurred on your computer. To find the last reboot time, look for an event with the ID “6009”. This event will contain the date and time of the last reboot.
For Linux environments:
cat /proc/stat | grep "btime"
Checking the last reboot time is a simple but important task that can help you to troubleshoot problems and ensure that your computer or server is running smoothly.
