"Virtual Machine" Grafana dashboard for Prometheus not working properly

[Franco-Sparrow]

Description

The "Virtual Machine" dashboard from the new opennebula native monitoring with Grafana and Prometheus is not working as expected. The information is not continuos and you have to wait hours to get new information from libvirt-exporter, to be reflected on the dashboard panels.

This is an example on my development cluster in v6.10.2:

Last 30 days

Last 6 hours

Last 30 min

To Reproduce

Configure OpenNebula Native Monitoring with prometheus and grafana. Import the gioven dashboard into the Grafana server and configure the Prometheus datastource. The Prometheus server will be the one installed in the opennebula forntend. Create a VM and wait for libvirt-exporter to serve the metrics for the VM. The dashboard will not show a consistent information.

Expected behavior

A continuos information like the others dashboards.
