# Cron Runner Load block

> Hourly runner time stacked bar chart with outcome toggles and a timeout burn callout

Cron job runner time over 24 hours as stacked hourly bars of succeeded, timed out and failed runs, with an average line and timeout burn callout. ToggleGroup chips hide an outcome and a docked tooltip names the slowest run. Recharts in a ReUI Frame.

## Best for

Hourly runner time stacked by outcome, with chips that hide an outcome, a docked tooltip naming the slowest run and a timeout burn pin

## Agent notes

- Replace `RAW_JOBS` in data.ts; `scheduledRun` fakes each duration from `baseDurationSec` and `timeoutMin`, so feed real `durationSec` per run
- `FLEET` is built once at module load from the fixed `REFERENCE_MS`, and the change against the prior 24h reads `priorSec` from the same seed
- `TIMEZONE_OFFSET_MIN` uses fixed summer offsets for New York and Dublin, so those jobs fall an hour off after a DST change

## When not to use

- Fleet KPI tiles for job health, success rate, failures and the next run: use [Cron Job Health](https://reui.io/blocks/chart/sparkline/chart-31.md) (`get_block("chart-31")`)
- Audit event volume with outcome chips and a draggable time range: use [Audit Log Volume](https://reui.io/blocks/chart/bar-chart/chart-35.md) (`get_block("chart-35")`)

## Install

```bash
npx shadcn@latest add @reui/chart-32
```

## About Bar Chart blocks

### When to use

- Values compared across hours, days or categories as grouped, stacked or hatched columns
- Run durations or event volumes against a timeout or limit line, with outcome toggles
- Segmented meters that split a capacity, a fund or a heart rate zone into colored slices

### When not to use

- A share of a whole where the slices read better around a ring: use the [Pie Chart blocks](https://reui.io/blocks/chart/pie-chart.md)
- A progress reading shown as an arc gauge with a status label: use the [Radial Chart blocks](https://reui.io/blocks/chart/radial-chart.md)
- Rows of jobs or deploys, each with its own run history strip: use the [Status Tracker blocks](https://reui.io/blocks/chart/status-tracker.md)

### Agent notes

- `Chart` renders with no props, so every bar, meter value and limit comes from constants kept in the block folder
