Monitoring Ubuntu Server Using Htop

Htop is an advanced, interactive system monitor process viewer written for Linux. It is designed to replace the Unix program top. It shows a frequently updated list of the processes running on a computer, normally ordered by the amount of CPU usage. Unlike 'top', Htop provides a full list of processes running, instead of the top resource consuming processes. Htop also uses color and gives visual information about processor, swap and memory status. - Wikipedia

Hiding Userland Threads
By default htop displays userland threads of processes like console-kit-daemon. To disable this feature;

Run htop
Press F2
Select "Display options"
Mark "Hide userland threads"
