Start the Ganglia daemons using the following command.

sudo /usr/local/sbin/gmond
sudo /usr/local/sbin/gmetad

Now, you can access the Ganglia web interface by navigating to http://<your-server-ip>/ganglia in a web browser.

Conclusion

In this tutorial, we learned how to install Ganglia on OpenSUSE Latest. You can now use Ganglia to monitor your cluster or grid system for performance and availability.
