Evaluate your results

Prometheus and Grafana are installed natively. Users can view simulation results by connecting to the Grafana pod on your EC2 instance:

0. Establish an SSH tunnel:

> ssh -L 3000:<REMOTE_HOST>:3000 ec2-user@<ec2-instance-ip>

1. Set up port forwarding:

> kubectl port-forward -n monitoring svc/grafana 3000

2. Open the Grafana UI

http://localhost:3000/

3. Create a Dashboard

• Dashboards > New > New Dashboard > Add visualization
• In the Data source field select prometheus
• In the Query field select Code
• Enter your PromQL query

Here are some queries to try:

See all simulated pods over time

sum(
  kube_pod_status_phase{
    phase="Running",
    namespace=~"virtual-.*"
    }
)

See all virtual KWOK nodes by instance type

sum(
  kube_node_status_condition{
    condition="Ready",
    status="true"
  }
  * on (node) group_right kube_pod_labels{
    label_type="virtual"
  }
)
by (label_node_kubernetes_io_instance_type)
