Guide on how to find out server uptime and login history

For those of you who use Linux OS, you can find out how long your server has been on. The easy way is to check the server uptime.

1. Open terminal
2. type in: uptime

xxx@komp:~$ uptime
08:40:14 up 6 days, 2:37, 1 user, load average: 0,67, 0,90, 1,03
   
   

From the results above, the information we can get is:

• The server has been on for over 6 days.
• The current position has only 1 user actively logged in.
• Average Load Average in 1 minute: 0.67, 5 minutes: 0.90, 15 minutes: 1.03 Where these results are good (still below the average number of server cores).

In addition to uptime, you can also get more detailed information, namely knowing the server login history.

1. Open terminal
2. type in: last

[root@wow ~]# last
