Libvirt dashboard

Libvirt Dashboard utilizes Prometheus to visualize metrics of VMs in Grafana.

Install Prometheus

$ sudo apt install prometheus

$ sudo systemctl status prometheus

Install Grafana

$ sudo apt-get install -y apt-transport-https software-properties-common wget

$ sudo mkdir -p /etc/apt/keyrings/

$ echo "deb [signed-by=/etc/apt/keyrings/grafana.gpg] https://apt.grafana.com stable main" | sudo tee -a /etc/apt/sources.list.d/grafana.list

$ echo "deb [signed-by=/etc/apt/keyrings/grafana.gpg] https://apt.grafana.com beta main" | sudo tee -a /etc/apt/sources.list.d/grafana.list

$ sudo apt-get update

$ sudo apt-get install grafana

$ sudo systemctl daemon-reload

$ sudo systemctl start grafana-server

$ sudo systemctl enable grafana-server

$ sudo systemctl status grafana-server

Install prometheus-libvirt-exporter (https://github.com/zhangjianweibj/prometheus-libvirt-exporter)

$ sudo apt install golang-go

$ go install github.com/goreleaser/goreleaser@latest

$ go install github.com/go-task/task/v3/cmd/task@latest

$ git clone https://github.com/zhangjianweibj/prometheus-libvirt-exporter.git

$ cd prometheus-libvirt-exporter/

$ go mod tidy

$ go mod vendor

$ go build ./...

$ go build

Configure Prometheus

$ nano /etc/prometheus/prometheus.yml

At the end of the file /etc/prometheus/prometheus.yml (within scrape_configs:), add the following:

  - job_name: 'libvirt_exporter'
    static_configs:
      - targets: ['localhost:9000']

$ sudo systemctl restart prometheus

Add a new data source connection of type Prometheus to Grafana. Include http://localhost:9090 as the connection URL.

Download or copy the dashboard in JSON: https://grafana.com/grafana/dashboards/15682-libvirt/

Import or paste it in Grafana

Run prometheus-libvirt-exporter to start capturing metrics (Grafana will visualize them automatically)

$ cd prometheus-libvirt-exporter

$ ./prometheus-libvirt-exporter
