Glances is an open source real time Linux server monitoring system that aims at providing as much as information possible in as minimum as space possible. Glances is like top command but more refined with many more features & much more real time information of your Linux system.

Glances provide information regarding memory, CPU, Disk IO , file system, Uptime, processes, interfaces, alerts & many other system information.

One of the best features of Glances is that it can work in server/client mode. We can perform remote monitoring of the systems using a Web interface or through terminal/CLI & we can also export stats to a file.

In this tutorial, we are going to discuss the installation of glances monitoring tool on CentOS/RHEL as well Ubuntu machines & also how to use it for real time Linux server monitoring of our system.

Installation of Glances monitoring

There are three ways with which we can install glances on CentOS/RHEL & Ubuntu systems. Either using system repositories or we can use pip (python package manager) or we can also use an official script for installation. PIP method & official script method is same on both Ubuntu & CentOS/RHEL.

Its recommended that we either use PIP or Official script to install Glances as repositories might hold older versions but none the less, let’s discuss all methods one by one…

CentOS/RHEL installation

On CentOS, glances packages are available with the EPEL repository. Install EPEL repository with the following command on your machine,


$ sudo dnf install


$ sudo rpm -Uvh

RHEL/CentOS 6 (64 Bit)

$ sudo rpm -Uvh

RHEL/CentOS 6 (32 Bit)

$ sudo rpm -Uvh

Once installed, run the following command to install glances tool,

$ sudo yum install glances

This will install glances tool on your machine.

Ubuntu Installation

Glances is available with the default Ubuntu repositories, so we can install glances easily on Ubuntu systems with the following command,

$ sudo apt-get install glances

Installation of Glances monitoring tool using PIP

If you have PIP installed on your system, than install glances on both CentOS/RHEL & Ubuntu systems using the following command,

$ pip install glances

If you don’t have PIP installed on your machine, read our detailed article on How to install PIP on Linux systems.

Installation of Glances monitoring tool using the Official script

This is another way with which we can install the latest version of glances on our CentOS/RHEL & Ubuntu systems. Open terminal & execute the following command,

$ sudo curl -L | /bin/bash

This will automatically install the glances on our system. We can also use following command in place of the one mentioned above, both achieve the same goal,

$ sudo wget -O- | /bin/bash

Using Glances in standalone mode

Once the glances tool has been installed on our machine, we can use it for real time Linux monitoring by opening the terminal & running the following command,

$ glances

Running Glances remotely

To remotely monitor the server from another machine, open terminal & run the following command,

$ glances -s

you should get the following output

Glances server is running on

Now open the remote machine from where you want to monitor the server & run the following command from the terminal,

$ glances -c

where is IP address of the server to be monitored.

Running Glances in Web server mode

To start the Glances in webserver mode, execute the following command from terminal,

$ glances -w

Once done, open the web browser & enter the following URL to access the Glances monitoring using web browser,

This will open the glances monitoring page for our server.
