• grafana dashboard (./grafana-dashboard/)

Get started

helm chart

prometheus-libvirt-exporter installation

git clone https://github.com/ycy1766/prometheus-libvirt-exporter.git
cd prometheus-libvirt-exporter
# helm version 2
helm install --name prometheus-libvirt-exporter -f values.yaml .
# helm version 3
helm install prometheus-libvirt-exporter -f values.yaml .

if you want to deploy exporter into specific nodes, you should modify nodeSelector.

prometheus example configuration

# sample
     - job_name: prometheus-libvirt-exporter
       kubernetes_sd_configs:
       - role: endpoints 
       relabel_configs:
       - source_labels: ['__meta_kubernetes_pod_label_exporter']
         separator: ;
         regex: libvirt
         replacement: $1
         action: keep

check label and set the nodeselector
