Cluster Health Dashboard ​

The dashboard is the first screen you see after logging into the Kipper web console. It provides a real-time overview of your cluster's health, showing the status of every infrastructure component, node resource usage, and any recent stability issues.

What the dashboard shows ​

Component status ​

The dashboard monitors up to 13 infrastructure components that make up a Kipper cluster. The list reflects the cluster's profile, component overrides, and storage and backup settings:

ComponentWhat it does
k3sLightweight Kubernetes distribution
TraefikIngress controller and reverse proxy
cert-managerAutomatic TLS certificate management
LonghornDistributed block storage
KEDAEvent-driven autoscaling
LokiLog aggregation
PromtailLog collection agent
PrometheusMetrics collection and alerting
GrafanaMetrics visualization
VeleroCluster backup and restore
DexIdentity and authentication provider
Console APIBackend API for the web console
ConsoleThe web console frontend

Each component shows a green or red indicator:

  • Green means a Deployment has at least one available replica, a StatefulSet has all its desired replicas ready, or a DaemonSet has at least one ready pod. For k3s, at least one node must be Ready.
  • Red means the component could not be found or checked, or it does not meet its readiness condition.

Node information ​

The nodes table shows every node in your cluster with:

  • Status: whether the node is Ready or NotReady.
  • CPU usage: current CPU consumption reported by metrics-server.
  • Memory usage: current memory consumption reported by metrics-server.
  • Disk usage: shown as "n/a" because disk usage is not collected.

CPU and memory values require metrics-server to be installed (it is included in a standard Kipper installation). If metrics-server is unavailable, the values display as "n/a".

OOM-killed pods ​

An amber warning banner appears if any pod was terminated due to running out of memory (OOMKilled) in the last 24 hours. Each entry shows the pod name, namespace, and the time the kill occurred.

If the kill is on a Kipper-managed app, OOM kills typically indicate that the app needs more memory than its resource limit allows. To resolve this:

  1. Open the app's resource settings in the console or run kip resources set.
  2. Increase the memory limit.
  3. Monitor the dashboard to confirm the kills stop.

If the kill is on a pod in the monitoring namespace (Prometheus or Loki), the row links to the Platform page. Kipper's auto-bump controller doubles the memory limit on system-component OOMs automatically, so you usually do not need to do anything. Open the Platform page to see the bump history, the current limit, and whether the component has hit its ceiling.

Node resource pressure ​

Two cards show real-time memory and CPU utilization for the cluster:

  • Utilization bar: color-coded green (<70%), amber (70% to below 90%), or red (90% and above)
  • Sparkline chart: a trend line showing the last hour of usage at a glance
  • Totals: current usage vs allocatable capacity

When memory exceeds 80%, the resource controller generates a warning alert with the top consumers and any anomalies. At 90%+, alerts are marked critical.

A Metrics are unavailable banner means Prometheus could not be reached. Treat the charts as stale or incomplete until monitoring recovers.

A table showing every Kipper-managed workload with:

  • Current memory: how much the workload is using right now
  • Sparkline: a mini trend chart of the last hour. Blue means stable, amber means growing, red means anomaly
  • Change indicator: percentage growth compared to ~10 minutes ago. Workloads that grew more than 30% are flagged as anomalies and highlighted in red

Anomalies are sorted to the top of the list, making it easy to spot a workload that is leaking memory or experiencing unexpected load growth before the node runs out of resources.

Resource management mode ​

The current resource management mode (Auto or Expert) and recent auto-mode changes are shown under Settings. In auto mode, the resource controller runs in the background and adjusts CPU/memory for your apps based on actual usage. See Resource Management for details on how the controller works and how to switch between modes.

Auto-refresh ​

The dashboard refreshes automatically every 30 seconds. You can also click the Refresh button to fetch the latest data immediately.

Troubleshooting ​

If a component shows red, check the following:

  1. Verify the component is deployed. Run kubectl get pods -n <namespace> to see if the pod exists.
  2. Check pod logs. Run kubectl logs -n <namespace> <pod-name> for error messages.
  3. Check events. Run kubectl get events -n <namespace> --sort-by=.lastTimestamp for recent issues.
  4. Restart the component. Run kubectl rollout restart deployment/<name> -n <namespace> if the pod is stuck.

If all components show red and you have just installed the cluster, wait a few minutes for everything to start. Initial provisioning can take 2-5 minutes depending on your server.
