Ganglia is a popular open-source software designed to monitor servers, clusters, and grids. It is compatible with various operating systems, including Linux. Installing Ganglia on Elementary OS Latest is a straightforward process, and this tutorial will guide you through the necessary steps.
Before installing Ganglia, ensure you have the following prerequisites:
The first step is to install the necessary dependencies for Ganglia to work correctly. Open the terminal on your Elementary OS Latest, then run the following command:
sudo apt-get install libconfuse-dev libapr1-dev libexpat1-dev rrdtool librrd-dev libaprutil1-dev gmetad apache2 libapache2-mod-php7.4 php7.4-mysql ganglia-monitor gmond
After installing the dependencies, we need to configure Ganglia to monitor your systems. To do this, we'll edit the configuration files:
First, navigate to the directory where the configuration files for Ganglia are stored:
cd /etc/ganglia/
Next, modify the gmetad configuration file by running:
sudo nano gmetad.conf
Change the data_source values to reflect the system you wish to monitor:
data_source "My Cluster" localhost
Save and close the file by pressing CTRL + X, then Y, and finally Enter.
Next, edit the gmond configuration file:
sudo nano gmond.conf
Change the cluster name to reflect your desired name:
cluster {
name = "My Cluster"
owner = "unspecified"
}
Again, save and close the file by pressing CTRL + X, then Y, and finally Enter.
After modifying the configuration files, we need to restart the services:
sudo systemctl restart gmetad
sudo systemctl start gmond
sudo systemctl enable gmond
sudo systemctl enable gmetad
Finally, we need to access Ganglia's web interface to view the monitoring data. Open any web browser of your choice and visit http://localhost/ganglia/ or use the IP address of the machine where Ganglia is installed. The web interface will display the monitoring data in real-time.
In this tutorial, we have installed Ganglia on Elementary OS Latest and configured it to monitor different systems. We hope you found this article informative, and it helps you monitor your various systems effectively.
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!
