SUSE Virtualization

Overview

Listing and inspecting your Harvester Virtual Machines can be achieved with the SUSE Virtualization stackpack. Running the SUSE Observability Agent on the internal Kubernetes cluster, metrics and VM details are propagated to SUSE® Observability.

Install Platform

Follow the Installing SUSE Observability guide to install SUSE® Observability.

Install the SUSE Virtualization StackPack

Go to main menu -> StackPacks -> SUSE Virtualization and install it. This will add a new main menu group:

To populate the overviews, observability data needs to flow from the Harvester cluster into SUSE® Observability.

Install Agent

Getting the Kubeconfig

In the Harvester UI, go to the Support page and download the KubeConfig.

Deploy the Agent

In SUSE® Observability, go to main menu -> StackPacks -> Kubernetes and add an instance. Record the cluster name, ingest URL and service token in a values.yaml file:

stackstate:
  apiKey: __SERVICE_TOKEN__
  cluster:
    name: __CLUSTER_NAME__
  url: __STACKSTATE_INGEST_URL__

otel:
  enabled: true
  k8sResourceCollector:
    integrations:
      suseVirtualization: true
      rancher: true

Follow the "Generic Kubernetes" installation instructions, with helm command:

helm upgrade --install \
  --kubeconfig /path/to/kubeconfig.yaml \
  --namespace suse-observability-agent \
  --values values.yaml \
  suse-observability-agent suse-observability/suse-observability-agent

Create ServiceMonitors

To ship metrics from Harvester to SUSE® Observability, you must create a couple of ServiceMonitors. Note that the label observability.suse.com/agent: scrape ensures that the service monitor is scraped by the OTEL integration of SUSE® Observability.

Verify SUSE Virtualization

The SUSE Observability Agent running in the Harvester cluster sends kubevirt.io custom resources, pod details and metrics to SUSE® Observability. You can validate the connection by checking the
