About this Hands-on Lab

In this lab, we’ll install `htop`, a resource utilization utility, and use it to look at system resource utilization. We’ll also use it to identify an active process and kill that process.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Install `htop`.
  1. To install htop, run the following command:

    sudo apt-get install -y htop
Kill the Xtightvnc process through `htop`.
  1. Start htop:

    sudo htop
  2. To kill the Xtightvnc process, scroll the highlighted row to the Xtightvnc service and press F9, then ENTER to send the kill command.

  3. Once the process is killed, it will disappear from the htop interface.

Additional Resources

There have been reports of one of the application servers running slow. One of the users reports that it's the Xtightvnc service causing the slowness. You have been tasked with logging in to the server to investigate. Your supervisor recommends you install htop and use that to view system resource utilization, and then kill the Xtightvnc process from within htop.
