Kubernetes Clusters Overview

The Overview tab is your operational summary for a cluster. It combines cluster identity, Gateway API status, health, capacity, integrations, and networking in a single page.

General

Section titled “General”

The General panel shows core cluster metadata:

  • Location: provider region for the cluster.
  • High Availability: whether control plane HA is enabled.
  • API Endpoint: Kubernetes API server address.
  • Cost: estimated monthly cost for the cluster.
  • Access:
    • Kubeconfig state (download, downloaded, or revoked).
    • SSH Key state (download or downloaded).

Gateway API (when available)

Section titled “Gateway API (when available)”

When Gateway API controllers are available, Overview shows a Gateway API panel with:

  • Primary endpoints for the primary Gateway class.
  • Aggregate traffic metrics from Envoy proxy metrics:
    • requests/s
    • 5xx
    • latency
    • connections
    • addresses (endpoint count)
  • Quick copy actions for the primary public addresses.

Envoy Gateway is the primary traffic entry point. Legacy NGINX ingress can still exist in the cluster, but Overview focuses on Gateway API endpoints.

Infrastructure Topology

Section titled “Infrastructure Topology”

Overview renders an interactive Infrastructure Topology panel that maps the cluster’s nodes, node pools, workloads, gateway endpoints, and networking in a single graph. The Gateway API metrics described above are surfaced within this panel.

Capacity & Health

Section titled “Capacity & Health”

This section is the live resource and node health snapshot:

  • CPU: allocatable, usage, requests, limits.
  • Memory: allocatable, usage, requests, limits.
  • Pods: healthy/running/completed status.
  • Node summary:
    • Control Plane count
    • Nodes count
    • Node Pools count
    • Total Nodes
    • Not Ready nodes
  • Diagnostics summary:
    • current warning count and warning shortcuts
    • Kubernetes event-derived warnings
    • pod issue and certificate-expiry rollups
  • Refresh: manual refresh and last-updated timestamp.

If detailed node metrics are not yet available, Overview falls back to estimated capacity values.

Diagnostics

Section titled “Diagnostics”

Overview includes a lightweight Diagnostics summary inside Capacity & Health for fast triage.

Use it to:

  • see whether the cluster currently has warnings
  • jump directly into the full Diagnostics page
  • identify warning sources such as pods, events, or K3s signals

For the full debugging workflow, open the dedicated Cluster Diagnostics page.

For retained logs, PromQL metrics exploration, and managed observability services, use the dedicated Cluster Observability workspace.

K3s Signals

Section titled “K3s Signals”

K3s Signals surfaces control plane health indicators:

  • Certificate expiry (critical/warning windows).
  • Snapshot health (successful vs failed etcd snapshots).
  • etcd + API signals (leader status, inflight requests, 5xx rate, etcd request latency).

When signals cannot be collected, the panel shows a metrics availability state.

For backup scheduling, encryption, and recovery workflows, use the dedicated Cluster Backups and Restore guide.

Node Details

Section titled “Node Details”

The Node Details section is collapsible and includes:

  • Ready node ratio and pod health summary.
  • Separate groups for Control Plane and Worker nodes.
  • Per-node expandable details (resources and pod status).
  • Quick controls to Expand all or Collapse all.

Kubernetes panel

Section titled “Kubernetes panel”

The Kubernetes card summarizes runtime configuration:

  • K3s version
  • OS image
  • CNI
  • CNI encryption (On/Off)
  • Secrets encryption (On/Off)

It also shows integration status:

  • GitOps (configured repo or not configured)
  • Registry (connected registry or not configured)

Deployments panel

Section titled “Deployments panel”

The Deployments card lists recent deployments for the cluster, including name and status for quick health checks.

Add-ons panel

Section titled “Add-ons panel”

The Add-ons card shows installed add-ons and versions so you can quickly verify platform capabilities on that cluster.

Networking panel

Section titled “Networking panel”

The Networking card provides:

  • Network capability badges: IPv4, IPv6, Private, Host Firewall.
  • Network details such as:
    • Private subnet (if enabled)
    • SSH allowed CIDRs
    • API allowed CIDRs
    • Host firewall state (Cilium)

Operational workspaces

Section titled “Operational workspaces”

Overview is the cluster summary page. Use the dedicated workspaces for deeper day-2 operations:
