Configuration options

In this document, you'll learn how to configure your custom visualization and what is in your visualization's nr1.json file. You'll know how to modify it, and how to use it to make your visualization more flexible and reusable.

Edit your visualization's metadata

The nr1.json file is a metadata file that lives in your visualization directory and looks something like this:

{
  "schemaType": "VISUALIZATION",
  "id": "fun-visualization",
  "displayName": "FunVisualization",
  "description": "",
  "configuration": []
}

nr1.json

It contains these top-level keys:

schemaType: Nerdpack items all have nr1.json metadata files. The schemaType describes the item's schema. For all visualizations, schemaType is VISUALIZATION.
id: Your visualization's string identifier. This must be unique within a given Nerdpack, but it doesn't need to be unique across all Nerdpacks.
displayName: The human-readable name that New Relic displays in Custom Visualizations.
description: The description that New Relic displays in Custom Visualizations.
configuration: A list of configurable properties for your visualization. You can edit these properties in the web UI and their values are passed to your visualization component.

Declare your visualization's configurable properties

To declare the configurable properties of your visualization, list them under the configuration key in the nr1.json file:

"configuration": [
    {
      "name": "nrqlQueries",
      "title": "NRQL Queries",
      "type": "collection",
      "items": [
        {
          "name": "accountId",
          "title": "Account ID",
          "description": "Account ID to be associated with the query",
          "type": "number"
        },
        {
          "name": "query",
          "title": "Query",
          "description": "NRQL query for visualization",
          "type": "nrql"
        }
      ]
    },
    {
      "name": "fill",
      "title": "Fill color",
      "description": "A fill color to override the default fill color",
      "type": "string"
    },
    {
      "name": "stroke",
      "title": "Stroke color",
      "description": "A stroke color to override the default stroke color",
      "type": "string"
    }
]

In this example, nrqlQueries is a collection of query objects. Each query object consists of an accountId and a query. As a collection, you can have multiple query objects in this visualization. fill and stroke are strings that define a color that you can use when rendering the visualization.

This is an example of configuration results in the following fields in the visualization's setup UI:

Notice the + next to NRQL Queries, which you can use to add query objects to the collection. You can also remove queries by hovering over them and clicking the -, if you've more than one. Also notice the tooltip provided for most of the fields. Each tooltip in the UI corresponds to its field's description, if it has one.

In your React code, you can access the values of these fields in your visualization component's props:

export default class MyCustomVisualization extends React.Component {
  render() {
    const { nrqlQueries, stroke, fill } = this.props;
    return <div>
      <p>Fill color: { fill }</p>
      <p>Stroke color: { stroke }</p>
      <p>First query account ID: { nrqlQueries[0].accountId }</p>
      <p>First query: { nrqlQueries[0].query }</p>
    </div>
  }

All configuration objects have the following optional keys:

name: The React component prop name
title: The UI display name
description: An tooltip description

All configuration objects require a type key that references the field's data type. Each data type is unique in how it's configured and presented.

`boolean`

A boolean property is rendered in the UI as a toggle and represents a true or false state.

  "schemaType": "VISUALIZATION",
  "id": "custom-viz",
  "displayName": "CustomViz",
  "description": "MyCustomViz",

      "title": "Show labels",
      "description": "Toggles the visibility of the chart's labels.",

    }
  ]

            </div>
        )
    }
}

index.js

`number`

A number property is rendered in the UI as a text field and represents a number. number props take three extra optional keys:

min: The minimum value the text field can take
max: The maximum value the text field can take
step: The interval between valid values

While these keys are available, they are not enforced. They are purely for UI purposes.

  "description": "MyCustomViz",
  "configuration": [
    {

index.js

`enum`

An enum property is rendered in the UI as a drop-down menu and represents a pre-defined list of choices. An enum takes an array of items, each with its own title and value. An item's title is its UI display title. Its value is its React component prop name.

        )
    }
}

index.js

`nrql`

A nrql property is rendered in the UI as a text box and represents a NRQL query. You can use the NrqlQuery component from the nr1 component library to query New Relic's database. You may need to transform the data to fit your visualization's needs.

  "displayName": "CustomViz",
  "description": "MyCustomViz",

        if (rawData) {
            return rawData.map((entry) => ({
                "name": entry.metadata.name,
                "val": entry.data[0].y,
                "fill": entry.metadata.color
            }));
        }
    }

    render() {
        const { query } = this.props;

        return (
            <NrqlQuery
                accountId={inputData.accountId}
                query={query}
            >
                {({ data }) => {
                    return <RadialBarChart
                        width={1000}
                        height={700}
                        data={this.transformData(data)}
                    >
                        <RadialBar
                            background dataKey='val'
                        />
                        <Legend
                            layout='vertical'
                            verticalAlign='middle'
                            align="right"
                        />
                    </RadialBarChart>
                }}
            </NrqlQuery>
        )
    }
}

重要

Although NRQL property can appear anywhere in your configuration, we strongly recommend putting it inside nrqlQueries collection and accompany it with account-id. This way we would be able to provide you with the best NRQL editing experience and other useful features (such as dashboard filtering) out of the box.

`account-id`

An account-id property is rendered in the UI as a drop-down menu and represents a New Relic account. From the menu, you can search for and select an account.

`namespace`

A namespace groups properties in the UI under a single heading. A namespace has items which are accessed in code, by name, as attributes of the namespace prop.

`collection`

A collection is a group of repeatable property sets or namespaces under a single heading. When you create a collection, you specify properties for the collection's child items. When you configure a collection in the UI, you can increase or decrease the amount of child items in the collection.

In code, you access the collection prop as an array of items.

index.js

Use `nr1.json`

You can freely edit nr1.json, but unlike index.js your locally served visualization requires a restart to see its changes. So, if you're serving your visualization locally, teardown your local server with CTRL+C and spin it up again:

bash

$nr1 nerdpack:serve

If your visualization is already published, you need to update your Nerdpack's version in package.json and publish and subscribe to the new version:

bash

$nr1 nerdpack:publish
$nr1 nerdpack:subscribe

Edit your visualization's metadata .css-21sua1{background:none;border:none;width:0;padding:0;}

Declare your visualization's configurable properties

boolean

string

number

json

enum

nrql

重要

account-id

namespace

collection

Use nr1.json

Edit your visualization's metadata

`boolean`

`string`

`number`

`json`

`enum`

`nrql`

`account-id`
