General

This package is an Ember addon that wraps @sentry/browser, with added functionality related to Ember. All methods available in @sentry/browser can be imported from @sentry/ember.

Installation

As with other Ember addons, run: ember install @sentry/ember

Then add the following to your <your-app>/app.js

  import * as Sentry from "@sentry/ember";

  Sentry.init({
    dsn: '__DSN__' // replace __DSN__ with your DSN,

    // Set tracesSampleRate to 1.0 to capture 100%
    // of transactions for performance monitoring.
    // We recommend adjusting this value in production,
    tracesSampleRate: 1.0,
  });

Usage

To use this SDK, call Sentry.init before the application is initialized, in app.js. This will allow Sentry to capture information while your app is starting. Any additional SDK settings can be modified via the usual config in environment.js for you, see the Additional Configuration section for more details.

import Application from '@ember/application';
import Resolver from 'ember-resolver';
import loadInitializers from 'ember-load-initializers';
import config from './config/environment';
import * as Sentry from "@sentry/ember";

Sentry.init({
  dsn: '__DSN__' // replace __DSN__ with your DSN,

  // Set tracesSampleRate to 1.0 to capture 100%
  // of transactions for performance monitoring.
  // We recommend adjusting this value in production,
  tracesSampleRate: 1.0,
});

export default class App extends Application {
  modulePrefix = config.modulePrefix;
  podModulePrefix = config.podModulePrefix;
  Resolver = Resolver;
}

Additional Configuration

Aside from configuration passed from this addon into @sentry/browser via the sentry property, there is also the following Ember specific configuration:

ENV['@sentry/ember'] = {
  // Will disable automatic instrumentation of performance.
  // Manual instrumentation will still be sent.
  disablePerformance: true,

  // All runloop queue durations will be added as spans.
  minimumRunloopQueueDuration: 0,

  // Will disable automatic instrumentation for components.
  disableInstrumentComponents: true,

  // All (non-glimmer) component render durations will be added as spans.
  minimumComponentRenderDuration: 0,

  // All component definitions will be added as spans.
  enableComponentDefinition: true,
};

Disabling Performance

@sentry/ember captures performance by default, if you would like to disable the automatic performance instrumentation, you can add the following to your config/environment.js:

ENV['@sentry/ember'] = {
  disablePerformance: true, // Will disable automatic instrumentation of performance. Manual instrumentation will still be sent.
};

Performance

Routes

If you would like to capture beforeModel, model, afterModel and setupController times for one of your routes, you can import instrumentRoutePerformance and wrap your route with it.

import Route from '@ember/routing/route';
import { instrumentRoutePerformance } from '@sentry/ember';

class MyRoute extends Route {
  model() {
    //...
  }
}

export default instrumentRoutePerformance(MyRoute);

Runloop

The runloop queue durations are instrumented by default, as long as they are longer than a threshold (by default 5ms). This helps (via the render queue) capturing the entire render in case component render times aren't fully instrumented, such as when using glimmer components.

If you would like to change the runloop queue threshold, add the following to your config:

ENV['@sentry/ember'] = {
  minimumRunloopQueueDuration: 0, // All runloop queue durations will be added as spans.
};

Components

Non-glimmer component render times will automatically get captured.

If you would like to disable component render being instrumented, add the following to your config:

ENV['@sentry/ember'] = {
  disableInstrumentComponents: true, // Will disable automatic instrumentation for components.
};

Additionally, components whose render time is below a threshold (by default 2ms) will not be included as spans. If you would like to change this threshold, add the following to your config:

ENV['@sentry/ember'] = {
  minimumComponentRenderDuration: 0, // All (non-glimmer) component render durations will be added as spans.
};

Glimmer components

Currently glimmer component render durations can only be captured indirectly via the runloop instrumentation. You can optionally enable a setting to show component definitions (which will indicate which components are being rendered) be adding the following to your config:

ENV['@sentry/ember'] = {
  enableComponentDefinition: true, // All component definitions will be added as spans.
};

Supported Versions

• Ember.js: v4.0 or above
• Node: v14.18 or above

Previous Integration

Previously we've recommended using the Ember integration from @sentry/integrations but moving forward we will be using this Ember addon to offer more Ember-specific error and performancing monitoring.

Testing

For this package itself, you can find example instrumentation in the dummy application, which is also used for testing. To test with the dummy application, you must pass the dsn as an environment variable.
