AppSignal now offers Apollo Gateway support, giving you span-level gateway performance insights to enhance Apollo Gateway performance in your Node.js applications.

In this blog post, we'll give you a whistle-stop tour of how to instrument and monitor Apollo Gateway requests in your Node.js application.

Getting Started

AppSignal's Apollo Gateway support helps you:

• ✅ Identify expensive N+1 queries
• ✅ Analyze root spans
• ✅ Squash bugs in your gateway, subgraphs, and beyond
• ✅ Quickly analyze root spans to find and fix bottlenecks

You can instrument Apollo Gateway in just three simple steps:

1. Upgrade Your AppSignal Package

Ensure your Node.js application is using version 3.3.0 or higher of the AppSignal package.

For example, with npm:

npm update @appsignal/nodejs

Or with yarn:

yarn upgrade @appsignal/nodejs

2. Disable Gateway GraphQL Instrumentation

For the Apollo Gateway instrumentation to work, you first need to disable GraphQL in your gateway service. This enables the gateway to send its own @apollo/gateway OpenTelemetry spans.

To do so, use the disableDefaultInstrumentations option in the AppSignal configuration:

const { Appsignal } = require("@appsignal/nodejs");

new Appsignal({
  active: true,
  name: "your-app-name",
  pushApiKey: "your-push-api-key",
  disableDefaultInstrumentations: ["@opentelemetry/instrumentation-graphql"],
});

3. Enable OpenTelemetry in the Apollo Gateway Config

To send @apollo/gateway OpenTelemetry spans to AppSignal, you need to enable telemetry in your Apollo Gateway config:

const config = {
  telemetry: {
    includeDocument: true,
    reportExceptions: 1,
  },
};

Monitoring Apollo Gateway With AppSignal

Let's say you're using Apollo Gateway to federate your Orders and Customers GraphQL servers:

What if we request the getAllOrders query from our Apollo Gateway service? AppSignal will instrument the gateway request to the Orders subgraph, giving you a high-level overview of how subgraphs in your gateway are performing:

At the same time, the query your gateway sends to the Orders subgraph is also instrumented with AppSignal's out-of-the-box GraphQL. So you gain the same deep, subgraph-level insights into query performance.
