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 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,
  "uid": "cLV5GDCkz",
  "title": "New dashboard",
  "tags": [],
  "style": "dark",
  "timezone": "browser",
  "editable": true,
  "hideControls": false,
  "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
id unique numeric identifier for the dashboard. (generated by the db)
uid unique dashboard identifier that can be generated by anyone. string (8-40)
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
graphTooltip 0 for no shared crosshair or tooltip (default), 1 for shared crosshair, 2 for shared crosshair AND shared tooltip
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
refresh auto-refresh interval
schemaVersion version of the JSON schema (integer), incremented each time a Grafana update brings changes to said schema
version version of the dashboard (integer), incremented each time the dashboard is updated
panels panels 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.

"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

"timepicker": {
    "collapse": false,
    "enable": true,
    "notice": false,
    "now": true,
    "refresh_intervals": [
      "5s",
      "10s",
      "30s",
      "1m",
      "5m",
      "15m",
      "30m",
      "1h",
      "2h",
      "1d"
    ],
    "status": "Stable",
    "time_options": [
      "5m",
      "15m",
      "1h",
      "3h",

      "4d",
      "7d",
      "30d"
    ],
    "type": "timepicker"
  }

Usage of the fields is explained below:

templating

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

 "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,
        "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"
      }
    ]
  }

Usage of the above mentioned fields in the templating section is explained below:

Name Usage

list an array of objects each representing one template variable
allFormat format to use while fetching all values from data source, eg: wildcard, glob, regex, pipe, etc.
current shows current selected variable text/value on the dashboard
