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. Click Edit in the top-right corner of the dashboard.
  2. Click Settings.
  3. Go to the JSON Model tab.
  4. When you’ve finished viewing the JSON, click Back to dashboard and Exit edit.

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": [],
  "timezone": "browser",
  "editable": true,
  "graphTooltip": 1,
  "panels": [],
  "time": {
    "from": "now-6h",
    "to": "now"
  },
  "timepicker": {
    "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:

NameUsage
idunique numeric identifier for the dashboard. (generated by the db)
uidunique dashboard identifier that can be generated by anyone. string (8-40)
titlecurrent title of dashboard
tagstags associated with dashboard, an array of strings
styletheme of dashboard, i.e. dark or light
timezonetimezone of dashboard, i.e. utc or browser
editablewhether a dashboard is editable or not
graphTooltip0 for no shared crosshair or tooltip (default), 1 for shared crosshair, 2 for shared crosshair AND shared tooltip
timetime range for dashboard, i.e. last 6 hours, last 7 days, etc
timepickertimepicker metadata, see timepicker section for details
templatingtemplating metadata, see templating section for details
annotationsannotations metadata, see annotations for how to add them
refreshauto-refresh interval
schemaVersionversion of the JSON schema (integer), incremented each time a Grafana update brings changes to said schema
versionversion of the dashboard (integer), incremented each time the dashboard is updated
panelspanels array, see below for detail.

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,
    "hidden": false,
    "nowDelay": "",
    "refresh_intervals": [
      "5s",
      "10s",
      "30s",
      "1m",
      "5m",
      "15m",
      "30m",
      "1h",
      "2h",
      "1d"
    ],
    "status": "Stable",
    "type": "timepicker"
  }

Usage of the fields is explained below:

NameUsage
collapsewhether timepicker is collapsed or not
enablewhether timepicker is enabled or not
notice
now
hiddenwhether timepicker is hidden or not
nowDelayoverride the now time by entering a time delay. Use this option to accommodate known delays in data aggregation to avoid null values.
refresh_intervalsinterval options available in the refresh picker dropdown
status
type

templating

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

json 
 "templating": {
    "enable": true,
    "list": [
      {
        "allFormat": "wildcard",
        "current": {
          "tags": [],
          "text": "prod",
          "value": "prod"
        },
        "datasource": null,
        "includeAll": true,
        "name": "env",
        "options": [
          {
            "selected": false,
            "text": "All",
            "value": "*"
          },
          {
            "selected": false,
            "text": "stage",
            "value": "stage"
          },
          {
            "selected": false,
            "text": "test",
            "value": "test"
          }
        ],
        "query": "tag_values(cpu.utilization.average,env)",
        "refresh": false,
        "type": "query"
      },
      {
        "allFormat": "wildcard",
        "current": {
          "text": "apache",
          "value": "apache"
        },
        "datasource": null,
        "includeAll": false,
        "multi": false,
        "multiFormat": "glob",
        "name": "app",
        "options": [
          {
            "selected": true,
            "text": "tomcat",
            "value": "tomcat"
          },
          {
            "selected": false,
            "text": "cassandra",
            "value": "cassandra"
          }
        ],
        "query": "tag_values(cpu.utilization.average,app)",
        "refresh": false,
        "regex": "",
        "type": "query"
      }
    ]
  }
