Best for: Four service health signals per region against their SLO or capacity, each a ring of the limit used over its window's key facts
When to use
- Error budget left per SLO objective as concentric rings beside burn rate and status
- A row of round meters, one per API or service metric, each with a trend delta
- Cash settled over a period on a radial day clock against a target ring
When not to use
- A KPI grid whose cells pair a delta badge with an area wedge in place of a gauge: use the KPI Area Charts block
- Uptime and coverage as two semicircle arc gauges with reviewer avatars: use the Error Budgets block
- Several sources sharing one total, read as slices of a ring: use the Pie Chart blocks
- A capacity or allocation meter laid out as straight segments in a row: use the Stats blocks

Shadcn API Health Block
API health KPI panel with SLO ring gauges, trend arrows and region scope. Part of the ReUI Shadcn Radial Chart blocks collection.
API health panel: availability, p95 latency, error rate and throughput as segmented SLO rings with a redline band, trend arrows vs the prior window, latest, peak and time past limit per region, auto refresh and CSV export.
It is composed from Badge, Button, Button Group, Dropdown Menu, Empty, Frame, Select, Skeleton, and more, so every part of it is a primitive you can restyle with your own design tokens.
What You Can Build With the API Health Block
- Install it with the ReUI registry command in the toolbar above, then swap the placeholder content, data wiring, and business logic for your own.
- Compare it across all eight ReUI styles and both the Base UI and Radix bases in the customizer before committing to one direction.
- Combine it with the other Shadcn Radial Chart blocks to assemble a full screen instead of a single section.
