Features of Monitorix
It shows the following features of the Linux operating system in Graphs:
- CPU Load & Process Statistics
- Network Usage and Traffic
- Per processor Kernel usage
- Services status

We need to set up EPEL repository to install the required packages.
#rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Now install epel-release:
#yum install epel-release -y
We can install monitorix packages from epel repository:
#yum install monitorix -y
Enable, Start and check status of the monitorix:
- systemctl enable monitorix
- systemctl start monitorix
- systemctl status monitorix
We need to configure the firewall to allow port 8080 to access the Dashboard of the Monitorix in the browser.
First We need to install and start firewalld in the machine:
#yum install firewalld -y
#systemctl start firewalld
Now We can add firewall rules to allow port 8080 to access the Monitorix Dashboard from external Machine:
#firewall-cmd –permanent –zone=public –add-port=8080/tcp
