Every Linux guru loves to show off their L33T (elite) cli skills, but sometimes a nice GUI rules. Like when you are monitoring a bunch of servers and just don’t feel like messing around with cryptic commands and ascii characters.
One tool I like for a simple overall of servers is “Cockpit”. After you log in it gives you the basics every sysadmin wants, CPU, Memory, Disk I/O and Network Traffic.
You can get details by selecting the appropriate selection in the sidebar. It’s not the most feature rich server GUI, but it nails the basics, it’s easy to install, and it does the job. Did I mention it’s free?
The CLI commands to find your Linux version are easy as pie, but they are also easy as pie to forget. Let this post be your goto reminder. To use these commands, simply open a terminal shell. Then type in any of the commans below. Don’t type the dollar sign that’s preceding each command; It just represents the shell prompt.
