I need to know when my server was rebooted? I only see my last login when I login.

Where is this info stored?

You can use last to see login information. To know about system reboot, enter in a terminal,

last | grep reboot

or simply,

last reboot

as mentioned by RebootDeluxe in the comment.

  • last | grep reboot does not work (anymore). It gives me no answer. Only last reboot works. As mentioned in answer from @dimidak I use Ubuntu 16.04.7 LTS Apr 8 at 11:27
  • @RebootDeluxe last | grep reboot is still working for me on Ubuntu 20.04.6 LTS. Without more information, I cannot say why it is not working for you. I am adding your method to the original post. Sorry for the delayed response.

You can run the uptime command from the console to see how long the server has been running. This will give the total amount of time since the last reboot.
