Overview

This Chapter contains documentation on how to configure OpenNebula to work with the Prometheus monitoring and alerting toolkit. The integration consists of four components:

• A Libvirt Exporter that provides information about VM (KVM domains) running on an OpenNebula Host.
• An OpenNebula Exporter that provides basic information about the overall OpenNebula cloud.
• Alert rules sample files based on the provided metrics.
• Grafana dashboards to visualize VM, Host, and OpenNebula information in a convenient way.

How Should I Read This Chapter

Before reading this Chapter, you should have already installed your Front-end and KVM Hosts, and have an OpenNebula cloud up and running with at least one virtualization node.

This Chapter is structured as follows:

• The installation guide describes the installation and basic configuration of the integration.
• How to visualize monitor data with Grafana is explained in a dedicated Section.
• Specific procedures to set up alarms is also addressed in this Chapter.

Finally, you can find a reference of the metrics gathered by the exporters here.
