# Overview (Cluster Intelligence)

> Real-time health scoring, version status, and issue detection for the selected cluster.

The Overview page is the landing view for each cluster in Pastures. It provides a single-pane summary of cluster health, active issues, and version status.

## Health score

A prominent card displays the cluster's **health score** (0–100) computed from multiple signals: node readiness, workload stability, etcd health, certificate expiry, and resource pressure.

The card also shows a **trend indicator** (improving, stable, or degrading) based on score history.

<Info>
  In demo mode, the health score is fixed at **87** with a **stable** trend.
</Info>

## Stat cards

Below the health score, summary cards show at-a-glance metrics:

* Node count and readiness
* Pod status breakdown
* Active issue count
* Cluster version and distribution

## Issue list

Active issues are listed with severity badges and a brief description. Each issue includes a **Diagnose →** link that opens the [Pastures AI drawer](/features/pastures-ai) pre-filled with the issue context.
