This article mainly explains "how to install and use Glances on Ubuntu system". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to install and use Glances on Ubuntu systems.

Glances is an open source command line system monitoring tool for Linux and BSD. It is developed in Python language and can monitor information such as CPU, load, memory, disk ID O, network traffic, file system, system temperature and so on.

Glances provides Unix and Linux performance experts with the ability to monitor and analyze performance data, including:

CPU utilization rate

Memory usage

Kernel statistics and run queue information

Disk Icano speed, transfer and read / write ratio

Free space in the file system

Disk adapter

Network Icano speed, transmission and read / write ratio

Page space and page speed

Processes that consume the most resources

Computer information and system resources

The glances tool can display important system information on the user's terminal in real time and update it dynamically. This efficient tool can work on any terminal screen. In addition, it does not consume a lot of CPU resources, usually less than 2%. Glances displays the data on the screen and updates it every two seconds. You can also change this interval to a longer or shorter value yourself. The glances tool can also capture the same data to a file, making it easier to analyze and graph the report later. The output file can be in spreadsheet format (.csv) or html format.
