Ganglia is a scalable and distributed monitoring system used to monitor clusters, grids, and other computing systems. This tutorial will guide you through the process of installing Ganglia on Fedora CoreOS Latest.
Before starting with the installation process, make sure that you have the following prerequisites:
A running instance of Fedora CoreOS Latest
Root or administrative privileges to execute commands on the system
A stable and reliable Internet connection
Follow the steps below to install Ganglia on Fedora CoreOS Latest:
To install Ganglia, we need to first install the EPEL repository. Run the following command to install the EPEL repository:
sudo dnf install epel-release -y
Use the following command to install the necessary Ganglia packages:
sudo dnf install ganglia-gmond ganglia-web httpd php php-gd php-xml -y
Once the packages are installed, we need to configure Ganglia. Open the /etc/ganglia/gmond.conf configuration file using a text editor, and make the following changes:
cluster {
name = "my_cluster"
owner = "my_organization"
latlong = "unknown"
url = "unknown"
}
udp_send_channel {
host = localhost
port = 8649
ttl = 1
}
udp_recv_channel {
port = 8649
}
tcp_accept_channel {
port = 8649
}
modules {
module {
name = "core_metrics"
path = "/usr/lib64/ganglia/modcore_metrics.so"
period = 60
timeout = 3
}
}
Save the file and exit the text editor.
Start the Ganglia monitoring service using the following command:
sudo systemctl start gmond
Enable the service to start at boot time using the following command:
sudo systemctl enable gmond
Initial configuration of the Ganglia web interface can be achieved through the following commands:
sudo systemctl enable httpd
sudo systemctl start httpd
sudo systemctl start mariadb
sudo /usr/sbin/gmetad
Then, copy the configuration file /usr/share/ganglia-webfrontend/conf_default.php to /usr/share/ganglia-webfrontend/conf.php. Now, edit /usr/share/ganglia-webfrontend/conf.php and add the following:
<?php
$conf['gweb_root'] = "/ganglia";
$conf['ganglia_ip'] = "localhost";
?>
With the installation in place and the settings configured, access the Ganglia web interface through your browser by navigating to http://localhost/ganglia. Ganglia should now be running and monitoring the system properly.
Congratulations! You have successfully installed and configured Ganglia on Fedora CoreOS Latest. You can now use Ganglia for monitoring your cluster or computing system.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
