How to Install Glances System Monitor on Ubuntu 22.04 LTS

Glances System Monitor is free, an open-source command-line tool for process monitoring, system resources such as CPU, Disk I/O, File System, Load Average, Memory, Network Interfaces, and processes. Glances are built with Python language. Glances support cross-platform monitoring, which can be used with a web-based interface.

One of the excellent features Glances supports is setting thresholds in the program. You can set careful, warning, and critical in the configuration file, which will then relay information in colors that can show alerts to systems resources bottlenecks, system resources issues, and much more. Glances, by default, comes with a pre-set list of colors, but you can modify and add additional configs.

The following tutorial will demonstrate how to install or enable and configure Glances System Monitor on Ubuntu 22.04 LTS Jammy Jellyfish Desktop or Server using the command line terminal.

Update Ubuntu

Update your system to ensure all existing packages are up to date using the following command.

sudo apt update && sudo apt upgrade -y

Install Glances System Monitor

By default, Ubuntu 22.04 repository features the Glances package, which makes installing the software straightforward. In your terminal, use the following command to begin the installation.

sudo apt install glances -y

Once installed, verify the version, which will check to see if it was installed successfully.

glances --version

Example output:

Glances should be started and ready to launch from your terminal by default. Verify this by using the following systemctl status command.

systemctl status glances

Example output:

If the service is not active for some reason, use the following command to enable and start it immediately.

sudo systemctl enable glances --now

How To Use Glances Monitoring System

Once you have installed the program, familiarize yourself with some of the basic commands that the tutorial will now cover.

To open Glances, use the following command.


Example terminal look:

How to Install Glances System Monitor on Ubuntu 22.04 LTS

To exit the Glances, use the following command.


Next, you can alternatively open Glances using a timer that may help systems in intensive tasks. By default, the timer is 1, but you can change this as an example:

glances -t 3

This now changes the default time delay from 1 second to 3 seconds. However, you can set this much higher if required.

To bring up the help command, enter the following.

glances -h

Example output:

Alerts in Glances

As mentioned at the start of the tutorial, Glances has the color for alerts. The following describes what they are.

  1. GREEN: OK (good)
  2. BLUE: CAREFUL (attention)
  3. VIOLET: WARNING (alert)
  4. RED: CRITICAL (critical)

The thresholds that default settings are as follows.

  • careful=50
  • warning=70
  • critical=90

The default configuration can be changed. To do this, open up the file located at /etc/glances/glances.conf. But firstly, let’s make a backup of the original configuration file for safekeeping which you can revert to if you make a mistake and need a fresh copy.

sudo cp /etc/glances/glances.conf /etc/glances/glances-bkup.conf

Next, open up the main configuration file using the nano text editor.

sudo nano /etc/glances/glances.conf

Scroll down, and you will start to see all the settings you can change.

For example, you would like to change the memory options.

Change from:


Change to:


As mentioned above, the tutorial has increased the warning signs. However, you can set your own and increase or even lower what you think is appropriate for your environment and use case.

Using the nano text editor, use CTRL+O and CTRL+X to save and exit the file.

Ideally, you should restart the service also using the following command.

sudo systemctl restart glances

Command Options

The following list commands you can use in Glances to configure, find and show what you are looking for.

aSort processes automatically
cSort processes by CPU%
mSort processes by MEM%
pSort processes by name
iSort processes by I/O rate
dShow/hide disk I/O stats

1Global CPU or per-CPU stats
hShow/hide this help screen
tView network I/O as combination
uView cumulative network I/O
qQuit (Esc and Ctrl-C also work)

How to Run Glances In Web Browser

Glances can do this for users who require remote monitoring, as all required dependencies are installed by default.

To initiate the browser function in the program, do the following.

glances -w

Note that you will most likely see in the terminal display “Glances Web User Interface started on” when entering this command. This may look a little confusing, using the server’s IP address.

You can set a password for the web-based monitor by typing the following command.

glances -w --password

To open the web browser for the program, enter your IP server address with the default port 61209 as an example.

For your primary client, you can keep glances running in the background with the following command.

glances -w &

The above creates a background running process. Now you must disown the current state.


If you need to kill the processors in background mode, type the following to kill all active glances sessions.

killall glances

How to Run Client-Server Mode

Another great feature of the Glances program is that it provides client-server architecture. This means you can run glances on multiple remote servers and connect them to your primary client, and all servers must have Glances installed.

Log in to the remote server, and start the glance program in server-side mode.

glances -s

After starting server-side monitoring on all the required servers you need, go to your client system and connect to the system’s IP address running the server-client mode with the following command.

glances -c server-IP-address

Optional – UFW Rules

Ubuntu 22.04 LTS, like previous versions, features the UFW firewall. If this is enabled, it may interfere with remote connections, and you will need to whitelist your IP address locally or externally. Below are some examples only of the most common.

UFW Allow Specific IP Address

For example, to allow for specified IP addresses, you are on an internal network and require the systems to communicate together, use the following command.

sudo ufw allow from

UFW Allow Specific IP Address on Specific Port

To enable an IP to connect to your system on a defined port (Glances port “61208”), type the following.

sudo ufw allow from to any port 61208

Allow Subnet Connections to a Specified Port

If you require a whole range of connections from an IP range subnet to a particular port, you can enable this by creating the following rule.

sudo ufw allow from to any port 61208

This will allow all IP addresses from to to connect to port 61208.

Comments and Conclusion

In the tutorial, you have learned how to install the Glances System Monitor on Ubuntu 22.04 LTS Jammy Jellyfish, which is a step above the default “top” package for monitoring system resources and processors that ships with default Ubuntu installations. This package is ideal, especially if you want a better system overview. It covers much more information and presents it in color codes to signal what the data in front of you means and how it affects your server.

The extra benefit of remote monitoring makes this one of the more popular options for simple server monitoring. It continues to get better with an active development continuing to this day.
