Graphing with JSON

If you query a Datadog timeboard though the dashboard API, the result is a JSON object with the following layout:

DASHBOARD_SCHEMA = {
    "type": "object",
    "properties": {
        "title": {"type": "string"},
        "description": {"type": "string"},
        "layout_type": {"enum": ["ordered", "free"]},
        "is_read_only": {"type": "boolean"},
        "template_variables": {"type": "array", "items": TEMPLATE_VARIABLE_SCHEMA},
        "notify_list": {"type": "array", "items": {"type": "string"}},
        "widgets": {
            "type": "array",
            "items": WIDGET_SCHEMA
        }
    },
    "required": ["title", "layout_type", "widgets"],
}

Parameter	Type	Description
`title`	string	Title of your dashboard.
`description`	string	Description of the dashboard.
`layout_type`	enum	Layout type of the dashboard. Available values are: `ordered` or `free`
`is_read_only`	Boolean	Whether this dashboard is read-only. If `true`, only the dashboard author and users with the Access Management (`user_access_manage`) permission can modify it.
`template_variables`	array of object	List of template variables for this dashboard. See the template variable schema documentation for more details.
`notify_list`	array of strings	List of handles of users to notify when changes are made to this dashboard.
`widgets`	array of object	List of widgets to display on the dashboard. See the dedicated Widget JSON schema documentation to build the `WIDGET_SCHEMA`.

Template variable schema

Dashboard template variables apply a new scope to one or more graphs on your dashboard. This allows you to dynamically explore metrics across different sets of tags by using variables instead of specific tags. To configure them through the Dashboard API, use the following layout:

TEMPLATE_VARIABLE_SCHEMA = {
    "type": "object",
    "properties": {
        "name": {"type": "string"},
        "default": {"type": "string"},
        "prefix": {"type": "string"},
    },
    "additionalProperties": false,
    "required": ["name"]
}
