How To Install Monitorix on AlmaLinux 8

This guide intends to teach you to Install Monitorix on AlmaLinux 8.

Monitorix is a free, open-source system monitoring tool that keeps track of several Linux services and system resources. This Linux system monitoring tool is composed of two programs. The first, Monitorix, is a system data logging daemon written in Perl. The second, its web interface uses the CGI script, monitorix.cgi.

Besides tracking Linux server elements such as overall system load, file system activity, and global kernel usage, Monitorix also tracks hardware data such as sub-system temperatures, battery status, and UPS statistics. It also monitors popular third-party Linux programs such as mail servers; libvirt-based virtual machines; and MySQL, Nginx, and MongoDB databases.

Configure Monitorix on AlmaLinux 8

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 AlmaLinux 8:

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 firewall-cmd --add-port=8080/tcp --permanent

Reload the firewall to apply the new rules:

sudo firewall-cmd --reload

Access Monitorix Web Interface

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.
