Dashboard JSON

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

To view the JSON of a dashboard, follow the steps mentioned below:

1. Go to a dashboard
2. Click on Manage dashboard menu on the top navigation bar
3. Select View JSON from the dropdown menu

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.

{
  "id": null,
  "title": "New dashboard",
  "tags": [],
  "style": "dark",
  "timezone": "browser",
  "editable": true,
  "hideControls": false,
  "sharedCrosshair": false,
  "rows": [],
  "time": {
    "from": "now-6h",
    "to": "now"
  },
  "timepicker": {
    "time_options": [],
    "refresh_intervals": []
  },
  "templating": {
    "list": []
  },
  "annotations": {
    "list": []
  },
  "schemaVersion": 7,
  "version": 0,
  "links": []
}

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

Name	Usage
id	unique dashboard id, an integer
title	current title of dashboard
tags	tags associated with dashboard, an array of strings
style	theme of dashboard, i.e. dark or light
timezone	timezone of dashboard, i.e. utc or browser
editable	whether a dashboard is editable or not
hideControls	whether row controls on the left in green are hidden or not
sharedCrosshair	TODO
rows	row metadata, see rows section for details
time	time range for dashboard, i.e. last 6 hours, last 7 days, etc
timepicker	timepicker metadata, see timepicker section for details
templating	templating metadata, see templating section for details
annotations	annotations metadata, see annotations section for details
schemaVersion	TODO
version	TODO
links	TODO

rows

rows field consists of an array of JSON object representing each row in a dashboard, such as shown below:

 "rows": [
    {
      "collapse": false,
      "editable": true,
      "height": "200px",
      "panels": [],
      "title": "New row"
    },
    {
      "collapse": true,
      "editable": true,
      "height": "300px",
      "panels": [],
      "title": "New row"
    }
  ]

Usage of the fields is explained below:

Name	Usage
collapse	whether row is collapsed or not
editable	whether a row is editable or not
height	height of the row in pixels
panels	panels metadata, see panels section for details
title	title of row

panels

Panels are the building blocks a dashboard. It consists of datasource queries, type of graphs, aliases, etc. Panel JSON consists of an array of JSON objects, each representing a different panel in a row. Most of the fields are common for all panels but some fields depends on the panel type. Following is an example of panel JSON representing a graph panel type:

        {
