New Relic Apollo Server plugin
[![npm status badge][5]][6] [![Apollo Server Plugin CI][1]][2] [![codecov][3]][4]
New Relic's official Apollo Server plugin for use with the Node.js agent. The supported Apollo Server version is 2.14 or later.
This plugin expects the Node.js agent newrelic npm package has already been installed in your application.
Installation
``
npm install newrelic
npm install @newrelic/apollo-server-plugin
`js
// index.js
const plugin = require('@newrelic/apollo-server-plugin')
// imported from supported module
const server = new ApolloServer({
typeDefs,
resolvers,
plugins: [plugin]
})
`
Getting started
The @newrelic/apollo-server-plugin exports a createPlugin function that does accept limited configuration. Since Apollo Server will invoke any function passed to plugins, invoking this yourself is not required unless you plan to override specific configuration.
To use the plugin without specific configuration, you can pass the function in directly similar to:
`js
// index.js
const plugin = require('@newrelic/apollo-server-plugin')
// imported from supported module
const server = new ApolloServer({
typeDefs,
resolvers,
plugins: [plugin]
})
`
Note: If you are using Typescript, you must pass in the appropriate ApolloServerPlugin type.
Using Apollo V4
`ts
// index.ts
import { ApolloServerPlugin, ApolloServer } from '@apollo/server';
import createNewRelicPlugin from '@newrelic/apollo-server-plugin';
const newRelicPlugin = createNewRelicPlugin
const server = new ApolloServer({
typeDefs,
resolvers,
plugins: [
newRelicPlugin,
],
});
`
Using Apollo V3
`ts
// index.ts
import { ApolloServer } from 'apollo-server';
import { ApolloServerPlugin } from 'apollo-server-plugin-base';
import createNewRelicPlugin from '@newrelic/apollo-server-plugin';
const newRelicPlugin = createNewRelicPlugin
const server = new ApolloServer({
typeDefs,
resolvers,
plugins: [
newRelicPlugin,
],
});
`
Usage
The New Relic plugin is known to work with the following Apollo Server modules:
* @apollo/server
*
*
* (>= 2.14)apollo-server-express
*
*
*
*
*
Other plugins may work, depending on their underlying implementation, but have not been verified.

Transaction and segment/span timings may be affected by other plugins used in the Apollo Server setup. In order to get more accurate resolver timings, it is recommended to add the New Relic plugin last.
`js`
const server = new ApolloServer({
typeDefs,
resolvers,
plugins: [
other_plugin,
newrelic_plugin
]
})$3
Configuration may be passed into the createPlugin function to override specific values. To override configuration, invoke the createPlugin function prior to passing to Apollo Server. The configuration object and all properties are optional.
`js`
const plugin = createPlugin({
captureScalars: true,
captureIntrospectionQueries: true,
captureServiceDefinitionQueries: true,
captureHealthCheckQueries: true,
captureFieldMetrics: true,
customResolverAttributes: () => { return { exampleAttribute: 'exampleValue' }},
customOperationAttributes: () => { return { exampleAttribute: 'exampleValue' }}
})
* [captureScalars = false] Enable capture of timing of fields resolved with theGraphQLScalarType
return type. This may be desired when performing time intensive
calculations to return a scalar value. This is not recommended for queries that return
a large number of pre-calculated scalar fields.
NOTE: query/mutation resolvers will always be captured even if returning a scalar type.
* [captureIntrospectionQueries = false] Enable capture of timings for an IntrospectionQuery.
* [captureServiceDefinitionQueries = false] Enable capture of timings for a Service Definition query received from an Apollo Federated Gateway Server.
* [captureHealthCheckQueries = false] Enable capture of timings for a Health Check query received from an Apollo Federated Gateway Server.
* [captureFieldMetrics = false] Enable capture of metrics for every field and resolver argument seen for an Apollo query. This is intended to be used to check for any unused fields in your graphql schema.
There are two configuration options for providing callbacks that can be used to define custom attributes. As their names suggest, customResolverAttributes will put custom attributes on the resolver segment and customOperationAttributes will use the operation segment.
The customResolverAttributes callback gets passed a resolverContext object corresponding to the attributes given to a resolver in Apollo server. The customOperationAttributes callback gets passed a requestContext argument. These arguments can be used to imbue more details into custom attributes. Both callbacks must return an object that will be used to define custom attribute key-value pairs. For example,
`js`
const plugin = createPlugin({
customResolverAttributes({ source, args, context, info }) {
return {
allArgs: Object.keys(args).join(','),
returnType: info.returnType.name,
sourceBranch: source?.branch
stage: context.event.requestContext.stage
}
},
customOperationAttributes(requestContext) {
return {
clientName: requestContext.request.http.headers.get('graphql-client-name')
}
}
})
$3
The New Relic plugin will work with an Apollo Federated Server out of the box. Just pass the plugin to the Federated Gateway Apollo Server. With the federated server you will get:
* Distributed Tracing support
* Transaction naming
* Operation naming
* Metrics
Resolver spans are not supported for the Federated Gateway Server. We strongly recommend adding the plugin to your sub-graph servers which will generate all the data you get with the Federated Server as well as resolver spans.
`js
// Federated Gateway Server index.js
const plugin = require('@newrelic/apollo-server-plugin')
const gateway = new ApolloGateway({
serviceList: [
{ name: 'server1', url: SERVER_1_URL },
{ name: 'server2', url: SERVER_2_URL }
]
});
const server = new ApolloServer({
gateway,
plugins: [ plugin ]
});
`
`js
// Sub-Graph server index.js
const { buildSubgraphSchema } = require('@apollo/federation');
const plugin = require('@newrelic/apollo-server-plugin')
const server = new ApolloServer({
schema: buildSubgraphSchema([{ typeDefs, resolvers }]),
plugins: [ plugin ]
});
`
NOTE: @apollo/federation and @apollo/gateway are currently 0.x versions and may break with future versions prior to 1.x release from Apollo.

Transactions are captured as web transactions, associated with the underlying framework (Express, Koa, etc.), and named based on the GraphQL operations executed.
Here's an example query and how that may be represented in NR One.
`graphql`
query {
libraries {
books {
title
author {
name
}
}
}
}
post /query/
For more information on how transactions are named, including how query errors may impact naming, please see the transaction documentation.
$3
Two new metrics have been introduced to understand the behavior of your GraphQL operations within and across transactions.
#### Operation Metrics
/GraphQL/operation/ApolloServer/[operation-type]/[operation-name]/[deepest-unique-path]
Operation metrics are very similar to how transaction names are constructed including the operation type, operation name and deepest unique path. These metrics represent the durations of the individual queries or mutations and can be used to compare outside of the context of individual transactions which may have multiple queries.
If you would like to have a list of the top 10 slowest operations, the following query can be used to pull the data on demand or as a part of a dashboard. The 'Bar' chart type is a recommended visualization for this query.
`sql`
FROM Metric SELECT average(newrelic.timeslice.value) * 1000
WHERE appName = '[YOUR APP NAME]' WITH METRIC_FORMAT 'GraphQL/operation/ApolloServer/{operation}'
FACET operation LIMIT 10
#### Field Resolve Metrics
/GraphQL/resolve/ApolloServer/[field-name]
Resolve metrics capture the duration spent resolving a particular piece of requested GraphQL data. These can be useful to find specific resolvers that may contribute to slowing down incoming queries.
If you would like to have a list of the top 10 slowest resolves, the following query can be used to pull the data on demand or as a part of a dashboard. The 'Bar' chart type is a recommended visualization for this query.
`sql`
FROM Metric SELECT average(newrelic.timeslice.value) * 1000
WHERE appName = '[YOUR APP NAME]' WITH METRIC_FORMAT 'GraphQL/resolve/ApolloServer/{field}'
FACET field LIMIT 10
For more information on metrics and some recommended visualizations, please see the metrics documentation.
$3
Segments and spans (when Distributed Tracing enabled) are captured for GraphQL operations, field resolution and additional work (when instrumented) that occurs as a part of field resolution such as making a query to a database.
#### Operation Segments/Spans
/GraphQL/operation/ApolloServer/[operation-type]/[operation-name]/[deepest-unique-path]
Operation segments/spans include the operation type, operation name and deepest unique path. These represent the individual duration and attributes of a specific invocation within a transaction or trace.
The operation type and operation name are captured as attributes on a segment or span as well as the query with obfuscated arguments.
For more information on collected attributes, see the segments and spans documentation
#### Field Resolve Segments/Spans
/GraphQL/resolve/ApolloServer/[path]
Resolve segments/spans leverage the resolution path of the individual field to best differentiate within a given trace or transaction. For example, libraries.books might be used instead of just books. These represent the individual duration and attributes of a specific field being resolved as a part of the GraphQL operation.
The field name, return type, parent type, path and arguments (disabled by default) are all captured as attributes.
For more information on collected attributes, including enabling args capture, see the segments and spans documentation
$3
The agent will notice GraphQL errors that get sent back to the client.
Depend on where the error was thrown, these will be associated with either the operation span or the specific field resolve span (Distribute Tracing enabled) to enable further debugging of issues.
Testing
The module includes a suite of unit and functional tests which should be used to
verify that your changes don't break existing functionality.
All tests are stored in tests/ and are written using.tap.js
Tap with the extension .
To run the full suite, run: npm test.
Individual test scripts include:
`
npm run unit
npm run integration
npm run versioned
