# Overview tab

Compact home dashboard for the **active** agent.

## KPIs

Top strip shows live scalars (CPU, RAM, load, net, health), filled from history seed and live samples.

| KPI | Notes |
|-----|--------|
| **CPU** | Percent used |
| **RAM used** | Auto-scales B → KiB → MiB → GiB → TiB |
| **Load 1m** | Plain load average |
| **Net RX** | Auto-scales b/s → kb/s → Mb/s → Gb/s |
| **Health** | Anomaly engine status (ok / degraded / critical) with tint |

## Sparks vs KPIs

Overview charts load from `queryData` history immediately; KPI labels sync from the same series so they are not stuck on `—` while graphs already have data.

## Spark panels

Six fixed panels (CPU, RAM, net, I/O, load, spotlight/explore):

- Heights grow modestly with window size (`clamp`) so the pane prefers to fit without scrolling.  
- Series depth follows the Charts timeframe when Charts has an active window; otherwise Settings → **Overview spark depth**.

## Fleet strip

When you have saved / linked hosts (or a parent fleet), a summary strip appears:

- Per-host status and short metrics when available  
- Click through to activate / connect  

Full management lives on the [Fleet](./fleet.md) tab.

## Spotlight / explore

The explore panel tracks a configurable chart id (Settings → **Default spotlight chart**, default `system.io`). Change it from Overview controls when present, or Settings.

## Tips

- Overview is for **at-a-glance**; deep investigation belongs on **Charts**.  
- If Overview feels cramped on a short display, the view may scroll — widen the window or collapse secondary chrome.
