[Super beginner's guide in 1 minute] Done! Checking system uptime for Linux-based OS

Hello!
I'm Inoue, the Persian cat at Beyond Shikoku office.

To put it more elegantly, as an MSP (Managed Service Provider), I frequently use the command "uptime"
. This command checks the system's uptime on Linux-based operating systems.
When a reboot occurs, the "uptime" command tells me when the reboot took place.

uptime command

Check system uptime

[root@test-aws-harukainoue ~]# uptime 07:56:53 up 16 min, 1 user, load average: 0.00, 0.00, 0.00

From left to right
: ■ Startup time
⇒ The system was started at 07:56:53 (hour:minute:second)
■ Time elapsed since startup
⇒ 16 minutes have passed since startup
■ Number of logged-in users
⇒ 1 user is currently logged in
■ Load average (1 minute, 5 minutes, 15 minutes) indicating load status
there is no load because no processes are running
thatuptime" command showed

summary

"uptime" command has no options.
So it seems simple, but
"uptimeyou don't know the
"uptime" command, if you don't know how to interpret the results, you won't know what to check.
It's a command that infrastructure engineers use surprisingly often!

I will continue to experiment and learn through trial and error,
and write blog posts about my favorite commands and commands that I personally want to understand better.

Growing every day, moving forward every day.
I must update myself every single day!!!
Thank you for reading to the end.
