• Left * * * Border inside the section, from top to bottom respectively, the network card eth0 receive and send, hard disk each partition read and write, here My computer is more idle, see all 0, the last is the root partition drive usage, there is no temperature module installed, you can install Lm_ Sensors software to monitor the motherboard, CPU operating voltage, fan speed, temperature and other data. It is convenient to check the temperature status of the love machine.

• The upper right half, the green border is, the current System Task window, that is, there are now 106 processes, 180 threads, 1 are running, 106 hibernate, no zombie process.

• The following red border is the details of the current process, which is only part of the following, mainly

VIRT	Virtual Memory Size
Res	The physical memory value that the process occupies
%cpu	CPU usage consumed by this process
%MEM	The percentage of physical memory and total memory that the process occupies
Pid	PID number of the process
USER	User name of the process owner
time+	Total CPU time elapsed after the process was started
Io_r	Read rate of the process
Io_w	The write rate of the process
NAME	The name of the process
NI	Priority of the process
S	Status of the process, s indicates hibernation, R is running, Z indicates zombie state

Use the H key to get help information

The role of the various keys behind the introduction of the English, here do not list out, do not know the meaning of, you can check the Internet,

are relatively simple in English. Now let's introduce some of the advanced uses of glances.

1. Display in HTML format, you need to install the appropriate software to display the HTML-formatted file

   #pip-python Install JINJA2

   #glances –o html–f/var/www/index.html

When the installation is complete, open the Web service and enter the address to access

1. Enter the CSV format file and open it using the LibreOffice Calc Tool

   #glances –o Csv–f/data/glances.csv

2. Glances how servers and clients work

   Glances supports server and client mode of operation, can realize remote monitoring, need to ensure that both machines are installed

   Glances Service

Start at server-side: glances–s–b 172.16.249.163 (IP address of client)

You can see that the port number of the glances is 61209 to ensure that the server-side firewall allows the client to connect, for convenience, here I

Let a machine do both server and client. Here is the client connection

#glances –c 172.16.249.163, you can see the machine running on the server side.
