# Dashboard JSON model

A dashboard in Grafana is represented by a JSON object, which stores metadata of its dashboard. Dashboard metadata includes dashboard properties, metadata from panels, template variables, panel queries, etc.

To view the JSON of a dashboard:

1. Navigate to a dashboard.
1. In the top navigation menu, click the **Dashboard settings** (gear) icon.
1. Click **JSON Model**.

## JSON fields

When a user creates a new dashboard, a new dashboard JSON object is initialized with the following fields:

> **Note:** In the following JSON, id is shown as null which is the default value assigned to it until a dashboard is saved. Once a dashboard is saved, an integer value is assigned to the `id` field.

```json
{
  "id": null,
  "uid": "cLV5GDCkz",
  "title": "New dashboard",
  "tags": [],
  "style": "dark",
  "timezone": "browser",
  "editable": true,
  "graphTooltip": 1,
  "panels": [],
  "time": {
    "from": "now-6h",
    "to": "now"
  },
  "timepicker": {
    "time_options": [],
    "refresh_intervals": []
  },
  "templating": {
    "list": []
  },
  "annotations": {
    "list": []
  },
  "refresh": "5s",
  "schemaVersion": 17,
  "version": 0,
  "links": []
}
```

Each field in the dashboard JSON is explained below with its usage:

| Name              | Usage                                                                                                             |

## Panels

Panels are the building blocks of a dashboard. It consists of data source queries, type of graphs, aliases, etc. Panel JSON consists of an array of JSON objects, each representing a different panel. Most of the fields are common for all panels but some fields depend on the panel type. Following is an example of panel JSON of a text panel.

```json
"panels": [
  {
    "type": "text",
    "title": "Panel Title",
    "gridPos": {
      "x": 0,
      "y": 0,
      "w": 12,
      "h": 9
    },
    "id": 4,
    "mode": "markdown",
    "content": "# title"
  }
```

### Panel size and position

The gridPos property describes the panel size and position in grid coordinates.

- `w` 1-24 (the width of the dashboard is divided into 24 columns)
- `h` In grid height units, each represents 30 pixels.
- `x` The x position, in same unit as `w`.
- `y` The y position, in same unit as `h`.

The grid has a negative gravity that moves panels up if there is empty space above a panel.

### timepicker

```json
"timepicker": {
    "collapse": false,
    "enable": true,
    "notice": false,
    "now": true,
    "refresh_intervals": [
      "5s",
      "10s",
      "30s",
      "1m",
      "5m",
      "15m",
      "30m",
      "1h",
      "2h",
      "1d"
    ],
    "status": "Stable",
    "type": "timepicker"
  }
```

Usage of the fields is explained below:

| Name                  | Usage                                  |
| --------------------- | -------------------------------------- |

| **now**               |                                        |
| **refresh_intervals** |                                        |
| **status**            |                                        |
| **type**              |                                        |

### templating

The `templating` field contains an array of template variables with their saved values along with some other metadata, for example:
