Htop also prints full command lines for processes, and allows one to scroll both vertically and horizontally for processes and command lines, respectively. It supports mouse operation, uses colour in its output and gives visual indications about the processor, memory and swap usage. Htop, which is a ncurses based process viewer, offers some very interesting options. It also displays additional information about the system uptime, current CPU and memory usage (or the total number of running processes), and allows you to perform actions such as sorting the list or killing a process. One such utility is the top command, which displays a real-time list of processes that are running on the system.

GNU/Linux provides various inbuilt utilities for this purpose. The task of system monitoring can be efficiently done with various sets of tools. Good system monitoring can help in maintaining operational continuity and avert any unwanted performance issues. The systems administrator should be aware of what processes are running on the system, how much memory or CPU resources are being utilised, who is logged in and so on. One of the most important responsibilities a systems administrator has is to monitor the systems in the network.

A system should always be free from malfunctions and should be continuously available to serve its purpose, and for this to happen, efficient system monitoring is a must. System monitoring is a very important activity for any organisation. It shows a complete list of the processes that are running and is easy to use. Htop is an interactive process viewer and a text mode application, which can do system monitoring efficiently in real-time.
