Install and Configure Monitorix on Ubuntu 22.04

In this guide, you will learn to Install and Configure Monitorix on Ubuntu 22.04.

Monitorix is a free, lightweight, open-source system monitoring tool designed to monitor as many services as possible.

This application monitors the CPU load and temperatures of the users on the system. Network device activity, network services demand, and even the devices’ interrupt activity are also monitored. The current status of any corporate server with Monitorix installed can be accessed via a web browser.

It has been designed to be used under production Linux servers, but due to its simplicity and small size, you can use it to monitor embedded devices.

Steps To Install and Configure Monitorix on Ubuntu 22.04

To complete this guide, you must log in to your server as a non-root user with sudo privileges and set up a basic firewall. For this purpose, you can visit our guide on Initial Server Setup with Ubuntu 22.04.

Monitorix Configuration on Ubuntu 22.04

Monitorix is configured with a single plain text configuration file /etc/monitorix/monitorix.conf. At this point, you need to make a few changes to the configuration file before using Monitorix.

Before you start, it is recommended to take a copy of the Monitorix config file:

sudo cp /etc/monitorix/monitorix.conf /etc/monitorix/monitorix.conf.backup

Now open the Monitorix config file with your favorite text editor, here we use the vi editor:

sudo vi /etc/monitorix/monitorix.conf

In the configuration file replace the settings according to your environment:

# line 6: change to any title you like
title = Monitorix

# line 7: change to your hostname
hostname = your-hostname

# line 8: background color of admin site
theme_color = black

# line 12: change network units to bps (default is Bytes per/sec)
netstats_in_bps = y

# 28-43: change if you need
<httpd_builtin>
        enabled = y
        host =
        port = 8080
        user = nobody
        group = nobody
        log_file = /var/log/monitorix-httpd
        # if enable permission for admin site, add settings
        hosts_deny = all
        hosts_allow = 10.0.0.0/24
        autocheck_responsiveness = y
        <auth>
                # if enable Basic auth, turn to [y]
                enabled = n
                msg = Monitorix: Restricted access
                htpasswd = /var/lib/monitorix/htpasswd
        </auth>
</httpd_builtin>

# line 76: set kind of graphs you'd like to monitor
# Graphs (de)activation
# -----------------------------------------------------------------------------
<graph_enable>
        system          = y
        kern            = y
        proc            = y
        hptemp          = n
        lmsens          = n
        gensens         = n
        ipmi            = n
        ambsens         = n
        nvidia          = n
        disk            = n
.....
.....

When you are done, save and close the file.

To apply the changes, restart the Monitorix service on Ubuntu 22.04:

sudo systemctl restart monitorix

Configure Firewall for Monitorix

If you have a running firewall, you must open port 8080 to enable access using the command below:

sudo ufw allow 8080/tcp

Reload the firewall to apply the new rules:

sudo ufw reload

Access Monitorix Dashboard

To access your Monitorix through the web interface, you need to type your server’s IP address in your web browser followed by 8080/monitorix:

http://server-ip-address:8080/monitorix

At the first screen, choose the graph and the daily, weekly, monthly, or yearly options and click ok.

From there, you can see your graphs and monitor your server.
