How To Install Monitorix on Debian 11?

To set up Monitorix on Debian 11, you must have access to your server as a non-root user with sudo privileges, and set up a basic firewall with UFW. To do this, you can follow our guide on Initial Server Setup with Debian 11.

Now follow the steps below to complete this guide.

Step 1 – Monitorix Installation on Debian 11

Monitorix packages are available in the default Debian 11 repository. First, you must run the system update to update your local packages:

sudo apt update

Then, run the command below in your terminal to install Monitorix and the required packages:

sudo apt install monitorix rrdtool perl libwww-perl libmailtools-perl libmime-lite-perl librrds-perl libdbi-perl libxml-simple-perl libhttp-server-simple-perl libconfig-general-perl libio-socket-ssl-perl -y

Step 2 – Verify Monitorix Installation

When your installation is completed, you can verify your Monitorix installation by checking its version. To do this, run the following command:

monitorix -v

In your output, you will see:

Monitorix version 3.12.0 (21-Feb-2020)

Step 3 – Start and Enable Monitorix Service

At this point, you must start and enable your Monitorix service to start on the boot system.

To perform this task, you can run the following command:

sudo systemctl enable --now monitorix

Then, verify your Monitorix service is active and running on your Debian 11 with the following command:

sudo systemctl status monitorix

You should get the following output:

● monitorix.service - Monitorix
     Loaded: loaded (/lib/systemd/system/monitorix.service; enabled; vendor pre>
     Active: active (running) since Tue 2023-05-23 03:42:42 EDT; 4min 5s ago
       Docs: man:monitorix(8)
   Main PID: 2509 (/usr/bin/monito)
      Tasks: 2 (limit: 4679)
     Memory: 80.6M
        CPU: 1.231s
     CGroup: /system.slice/monitorix.service
             ├─2509 /usr/bin/monitorix -c /etc/monitorix/monitorix.conf -p /run>
             └─2592 monitorix-httpd listening on 8080

Now proceed to the next step to configure your Monitorix service.

Step 4 – Configure Monitorix on Debian 11

You can easily configure your Monitorix service by using a simple text file /etc/monitorix/monitorix.conf

Before you start using your Monitorix, you need to make some configuration changes to this file.

First, it is highly recommended to take a copy of the Monitorix config file. To do this, you can use the following command:

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

Then, open the Monitorix config file on Debian 11 by using your desired text editor, here we use the vi editor:

sudo vi /etc/monitorix/monitorix.conf

From the configuration file, replace the following settings as 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
        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 =
        autocheck_responsiveness = y
                # if enable Basic auth, turn to [y]
                enabled = n
                msg = Monitorix: Restricted access
                htpasswd = /var/lib/monitorix/htpasswd

# line 76: set kind of graphs you'd like to monitor
# Graphs (de)activation
# -----------------------------------------------------------------------------
        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 Debian 11:

sudo systemctl restart monitorix

Configure Firewall for Monitorix

If you have a running firewall with UFW, 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

Step 5 – How To 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:

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.

Step 6 – How To Enable Multi-Host Monitoring with Monitorix?

If you plan to configure Monitorix on another node, you must set a monitoring target node in the Monitorix config file. To do this, open the Monitorix config file on Debian 11:

sudo vi /etc/monitorix/monitorix.conf

In the file, search for the <multihost> section. And make the configuration as shown below:

        # enable with [y]
        enabled = y
        footer_url = y
        graphs_per_row = 2
        default_option_when_all = "System load"
        # remote host list (display name)
        remotehost_list = Enter your Node List Here
        #remotehost_list = server 1, server 2, server 3
                # access path of remote hosts
                 0 =,/monitorix
                #0 =,/monitorix,/monitorix-cgi
                #1 =,/monitorix,/monitorix-cgi
                #2 =,/,/
        groups = n
        remotegroup_list = My Group
                0 = server 2, server 3

When you are done, save and close the file.

To apply the changes, restart Monitorix:

sudo systemctl restart monitorix

Then, access your Node controller from the web interface, for example,,/monitorix, and click the [Hostname], then you can select a Node and click ok.

From there, you can see your Node graphs.

That’s it you are done.


At this point, you have learned to install land configure Monitorix on Debian 11. You can see how to configure Monitorix to perform simple monitoring and enable Multi-Host monitoring. It is an easy-to-use Monitoring tool on Linux.
