# Asset Health Matrix

> A dashboard item with one tile per asset, grouped by plant or area and ordered worst first, coloured by a health index against two thresholds.

The **Asset Health Matrix**  shows one tile per asset with
its health index, so a maintenance planner sees at a glance which assets to look at first. Use it where a list of
machines would hide the few that need attention: a maintenance dashboard, a plant overview, a shift handover screen.

1. **Legend.** The colours and the thresholds they stand for: **Critical** below the critical threshold, **Watch**
   below the warning threshold, **Healthy** above both.
2. **Group.** One section per value of the **Group** field, such as a plant or an area. The figures on the right count
   the tiles in it by colour (critical, watch, healthy).
3. **Tile.** One asset: its health in percent, its name, its kind, the detail figure if you gave one, and a bar
   filled to its health. Within a group, tiles are ordered from the lowest health.

Select a tile to filter the other items of the dashboard by that asset.

## Data fields

**Asset** and **Health** are required; without them the item asks for them instead of drawing tiles. **Health** is
read as a percentage from 0 to 100. Leave **Group** empty for one section with every asset. **Detail** is a second
figure for each tile, such as vibration or temperature, shown as the field formats it.

## Settings

- **Warning below** and **Critical below** set the colours: a tile is critical below the critical threshold and
  needs watching below the warning threshold. Keep the critical threshold the lower of the two.
- **Detail label** is written after the detail figure, for its unit (for example `mm/s`).

## Where to see it

The Meridian demo plant uses it on **Meridian · Maintenance & Asset Health**, with one group per plant and vibration
as the detail figure.
