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

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.
Access:
- Kubeconfig state (download, downloaded, or revoked).
- SSH Key state (download or downloaded).

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
- avg latency
- active conns
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.

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

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.

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.

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

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

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

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

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)
