Monitoring and Alerting

This chapter contains documentation on how to configure OpenNebula to work with 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.
