What is Snowplow

Snowplow is an enterprise-grade marketing and Product Intelligence platform which helps track the way users engage with our website and application.

Snowplow consists of the following loosely-coupled sub-systems:

  • Trackers fire Snowplow events. Snowplow has 12 trackers, covering web, mobile, desktop, server, and IoT.
  • Collectors receive Snowplow events from trackers. We have three different event collectors, synchronizing events either to Amazon S3, Apache Kafka, or Amazon Kinesis.
  • Enrich cleans up the raw Snowplow events, enriches them and puts them into storage. We have an Hadoop-based enrichment process, and a Kinesis-based or Kafka-based process.
  • Storage is where the Snowplow events live. We store the Snowplow events in a flat file structure on S3, and in the Redshift and PostgreSQL databases.
  • Data modeling is where event-level data is joined with other data sets and aggregated into smaller data sets, and business logic is applied. This produces a clean set of tables which make it easier to perform analysis on the data. We have data models for Redshift and Looker.
  • Analytics are performed on the Snowplow events or on the aggregate tables.

Enable Snowplow tracking

Tracking can be enabled at:

  • The instance level, which enables tracking on both the frontend and backend layers.
  • The user level, though user tracking can be disabled on a per-user basis. GitLab respects the Do Not Track standard, so any user who has enabled the Do Not Track option in their browser is not tracked at a user level.

Snowplow tracking is enabled on GitLab.com, and we use it for most of our tracking strategy.

To enable Snowplow tracking on a self-managed instance:

  1. On the top bar, select Menu > {admin} Admin, then select Settings > General. Alternatively, go to admin/application_settings/general in your browser.

  2. Expand Snowplow.

  3. Select Enable Snowplow tracking and enter your Snowplow configuration information. For example:

    Name Value
    Collector hostname your-snowplow-collector.net
    App ID gitlab
    Cookie domain .your-gitlab-instance.com
  4. Select Save changes.

Snowplow request flow

Structured event taxonomy

When adding new click events, we should add them in a way that's internally consistent. If we don't, it is very painful to perform analysis across features since each feature captures events differently.

The current method provides several attributes that are sent on each click event. Please try to follow these guidelines when specifying events to capture:

attribute type required description
category text true The page or backend area of the application. Unless infeasible, please use the Rails page attribute by default in the frontend, and namespace + class name on the backend.
action text true The action the user is taking, or aspect that's being instrumented. The first word should always describe the action or aspect: clicks should be click, activations should be activate, creations should be create, etc. Use underscores to describe what was acted on; for example, activating a form field would be activate_form_input. An interface action like clicking on a dropdown would be click_dropdown, while a behavior like creating a project record from the backend would be create_project
label text false The specific element, or object that's being acted on. This is either the label of the element (e.g. a tab labeled 'Create from template' may be create_from_template) or a unique identifier if no text is available (e.g. closing the Groups dropdown in the top navigation bar might be groups_dropdown_close), or it could be the name or title attribute of a record being created.
property text false Any additional property of the element, or object being acted on.
value decimal false Describes a numeric value or something directly related to the event. This could be the value of an input (e.g. 10 when clicking internal visibility).

Examples

category* label action property** value
[root:index] main_navigation click_navigation_link [link_label] -
[groups:boards:show] toggle_swimlanes click_toggle_button - [is_active]
[projects:registry:index] registry_delete click_button - -
[projects:registry:index] registry_delete confirm_deletion - -
[projects:blob:show] congratulate_first_pipeline click_button [human_access] -
[projects:clusters:new] chart_options generate_link [chart_link] -
[projects:clusters:new] chart_options click_add_label_button [label_id] -

* It's ok to omit the category, and use the default.
** Property is usually the best place for variable strings.

Web-specific parameters

Snowplow JS adds many web-specific parameters to all web events by default.

Implementing Snowplow JS (Frontend) tracking

GitLab provides Tracking, an interface that wraps the Snowplow JavaScript Tracker for tracking custom events. The simplest way to use it is to add data- attributes to clickable elements and dropdowns. There is also a Vue mixin (exposing a track method), and the static method Tracking.event. Each of these requires at minimum a category and an action. You can provide additional Structured event taxonomy properties along with an extra object that accepts key-value pairs.

field type default value description
category string document.body.dataset.page Page or subsection of a page that events are being captured within.
action string generic Action the user is taking. Clicks should be click and activations should be activate, so for example, focusing a form field would be activate_form_input, and clicking a button would be click_button.
data object {} Additional data such as label, property, value, context (as described in our Structured event taxonomy), and extra (key-value pairs object).

Usage recommendations

  • Use data attributes on HTML elements that emits either the click, show.bs.dropdown, or hide.bs.dropdown events.
  • Use the Vue mixin when tracking custom events, or if the supported events for data attributes are not propagating.
  • Use the Tracking class directly when tracking on raw JS files.

Tracking with data attributes

When working within HAML (or Vue templates) we can add data-track-* attributes to elements of interest. All elements that have a data-track-action attribute automatically have event tracking bound on clicks. You can provide extra data as a valid JSON string using data-track-extra.

Below is an example of data-track-* attributes assigned to a button:

%button.btn{ data: { track: { action: "click_button", label: "template_preview", property: "my-template" } } }
<button class="btn"
  data-track-action="click_button"
  data-track-label="template_preview"
  data-track-property="my-template"
  data-track-extra='{ "template_variant": "primary" }'
/>

Event listeners are bound at the document level to handle click events on or within elements with these data attributes. This allows them to be properly handled on re-rendering and changes to the DOM. Note that because of the way these events are bound, click events should not be stopped from propagating up the DOM tree. If for any reason click events are being stopped from propagating, you need to implement your own listeners and follow the instructions in Tracking within Vue components or Tracking in raw JavaScript.

Below is a list of supported data-track-* attributes:

attribute required description
data-track-action true Action the user is taking. Clicks must be prepended with click and activations must be prepended with activate. For example, focusing a form field would be activate_form_input and clicking a button would be click_button. Replaces data-track-event, which was deprecated in GitLab 13.11.
data-track-label false The label as described in our Structured event taxonomy.
data-track-property false The property as described in our Structured event taxonomy.
data-track-value false The value as described in our Structured event taxonomy. If omitted, this is the element's value property or undefined. For checkboxes, the default value is the element's checked attribute or 0 when unchecked.
data-track-extra false A key-value pairs object passed as a valid JSON string. This is added to the extra property in our gitlab_standard schema.
data-track-context false The context as described in our Structured event taxonomy.

Available helpers

tracking_attrs(label, action, property) # { data: { track_label... } }

%button{ **tracking_attrs('main_navigation', 'click_button', 'navigation') }

Caveats

When using the GitLab helper method nav_link be sure to wrap html_options under the html_options keyword argument. Be careful, as this behavior can be confused with the ActionView helper method link_to that does not require additional wrapping of html_options

# Bad
= nav_link(controller: ['dashboard/groups', 'explore/groups'], data: { track_label: "explore_groups", track_action: "click_button" })

# Good
= nav_link(controller: ['dashboard/groups', 'explore/groups'], html_options: { data: { track_label: "explore_groups", track_action: "click_button" } })

# Good (other helpers)
= link_to explore_groups_path, title: _("Explore"), data: { track_label: "explore_groups", track_action: "click_button" }

Tracking within Vue components

There's a tracking Vue mixin that can be used in components if more complex tracking is required. To use it, first import the Tracking library and request a mixin.

import Tracking from '~/tracking';
const trackingMixin = Tracking.mixin({ label: 'right_sidebar' });

You can provide default options that are passed along whenever an event is tracked from within your component. For instance, if all events within a component should be tracked with a given label, you can provide one at this time. Available defaults are category, label, property, and value. If no category is specified, document.body.dataset.page is used as the default.

You can then use the mixin normally in your component with the mixin Vue declaration. The mixin also provides the ability to specify tracking options in data or computed. These override any defaults and allow the values to be dynamic from props, or based on state.

export default {
  mixins: [trackingMixin],
  // ...[component implementation]...
  data() {
    return {
      expanded: false,
      tracking: {
        label: 'left_sidebar',
      },
    };
  },
};

The mixin provides a track method that can be called within the template, or from component methods. An example of the whole implementation might look like this:

export default {
  name: 'RightSidebar',
  mixins: [Tracking.mixin({ label: 'right_sidebar' })],
  data() {
    return {
      expanded: false,
    };
  },
  methods: {
    toggle() {
      this.expanded = !this.expanded;
      // Additional data will be merged, like `value` below
      this.track('click_toggle', { value: Number(this.expanded) });
    }
  }
};

The event data can be provided with a tracking object, declared in the data function, or as a computed property. A tracking object is convenient when the default event properties are dynamic or provided at runtime.

export default {
  name: 'RightSidebar',
  mixins: [Tracking.mixin()],
  data() {
    return {
      tracking: {
        label: 'right_sidebar',
        // category: '',
        // property: '',
        // value: '',
        // experiment: '',
        // extra: {},
      },
    };
  },
};

The event data can be provided directly in the track function as well. This object will merge with any previously provided options.

this.track('click_button', {
  label: 'right_sidebar',
});

Lastly, if needed within the template, you can use the track method directly as well.

<template>
  <div>
    <button data-testid="toggle" @click="toggle">Toggle</button>

    <div v-if="expanded">
      <p>Hello world!</p>
      <button @click="track('click_action')">Track another event</button>
    </div>
  </div>
</template>

Testing example

import { mockTracking } from 'helpers/tracking_helper';
// mockTracking(category, documentOverride, spyMethod)

describe('RightSidebar.vue', () => {
  let trackingSpy;
  let wrapper;

  beforeEach(() => {
    trackingSpy = mockTracking(undefined, wrapper.element, jest.spyOn);
  });

  const findToggle = () => wrapper.find('[data-testid="toggle"]');

  it('tracks turning off toggle', () => {
    findToggle().trigger('click');

    expect(trackingSpy).toHaveBeenCalledWith(undefined, 'click_toggle', {
      label: 'right_sidebar',
      value: 0,
    });
  });
});

Tracking in raw JavaScript

Custom event tracking and instrumentation can be added by directly calling the Tracking.event static function. The following example demonstrates tracking a click on a button by calling Tracking.event manually.

import Tracking from '~/tracking';

const button = document.getElementById('create_from_template_button');

button.addEventListener('click', () => {
  Tracking.event('dashboard:projects:index', 'click_button', {
    label: 'create_from_template',
    property: 'template_preview',
    extra: {
      templateVariant: 'primary',
      valid: 1,
    },
  });
});

Testing example

import Tracking from '~/tracking';

describe('MyTracking', () => {
  let wrapper;

  beforeEach(() => {
    jest.spyOn(Tracking, 'event');
  });

  const findButton = () => wrapper.find('[data-testid="create_from_template"]');

  it('tracks event', () => {
    findButton().trigger('click');

    expect(Tracking.event).toHaveBeenCalledWith(undefined, 'click_button', {
      label: 'create_from_template',
      property: 'template_preview',
      extra: {
        templateVariant: 'primary',
        valid: true,
      },
    });
  });
});

Form tracking

You can enable Snowplow automatic form tracking by calling Tracking.enableFormTracking (after the DOM is ready) and providing a config object that includes at least one of the following elements:

  • forms: determines which forms are tracked, and are identified by the CSS class name.
  • fields: determines which fields inside the tracked forms are tracked, and are identified by the field name.

An optional list of contexts can be provided as the second argument. Note that our gitlab_standard schema is excluded from these events.

Tracking.enableFormTracking({
  forms: { allow: ['sign-in-form', 'password-recovery-form'] },
  fields: { allow: ['terms_and_conditions', 'newsletter_agreement'] },
});

Testing example

import Tracking from '~/tracking';

describe('MyFormTracking', () => {
  let formTrackingSpy;

  beforeEach(() => {
    formTrackingSpy = jest
      .spyOn(Tracking, 'enableFormTracking')
      .mockImplementation(() => null);
  });

  it('initialized with the correct configuration', () => {
    expect(formTrackingSpy).toHaveBeenCalledWith({
      forms: { allow: ['sign-in-form', 'password-recovery-form'] },
      fields: { allow: ['terms_and_conditions', 'newsletter_agreement'] },
    });
  });
});

Implementing Snowplow Ruby (Backend) tracking

GitLab provides Gitlab::Tracking, an interface that wraps the Snowplow Ruby Tracker for tracking custom events.

Custom event tracking and instrumentation can be added by directly calling the GitLab::Tracking.event class method, which accepts the following arguments:

argument type default value description
category String Area or aspect of the application. This could be HealthCheckController or Lfs::FileTransformer for instance.
action String The action being taken, which can be anything from a controller action like create to something like an Active Record callback.
label String nil As described in Structured event taxonomy.
property String nil As described in Structured event taxonomy.
value Numeric nil As described in Structured event taxonomy.
context Array[SelfDescribingJSON] nil An array of custom contexts to send with this event. Most events should not have any custom contexts.
project Project nil The project associated with the event.
user User nil The user associated with the event.
namespace Namespace nil The namespace associated with the event.
extra Hash {} Additional keyword arguments are collected into a hash and sent with the event.

Tracking can be viewed as either tracking user behavior, or can be used for instrumentation to monitor and visualize performance over time in an area or aspect of code.

For example:

class Projects::CreateService < BaseService
  def execute
    project = Project.create(params)

    Gitlab::Tracking.event('Projects::CreateService', 'create_project', label: project.errors.full_messages.to_sentence,
                           property: project.valid?.to_s, project: project, user: current_user, namespace: namespace)
  end
end

Unit testing

Use the expect_snowplow_event helper when testing backend Snowplow events. See testing best practices for details.

Performance

We use the AsyncEmitter when tracking events, which allows for instrumentation calls to be run in a background thread. This is still an active area of development.

Test frontend events

To test frontend events in development:

Snowplow Analytics Debugger Chrome Extension

Snowplow Analytics Debugger is a browser extension for testing frontend events. This works on production, staging and local development environments.

  1. Install the Snowplow Analytics Debugger Chrome browser extension.
  2. Open Chrome DevTools to the Snowplow Analytics Debugger tab.
  3. Learn more at Igloo Analytics.

Snowplow Inspector Chrome Extension

Snowplow Inspector Chrome Extension is a browser extension for testing frontend events. This works on production, staging and local development environments.

  1. Install Snowplow Inspector.
  2. Open the Chrome extension by pressing the Snowplow Inspector icon beside the address bar.
  3. Click around on a webpage with Snowplow and you should see JavaScript events firing in the inspector window.

Snowplow Micro

Snowplow Micro is a very small version of a full Snowplow data collection pipeline: small enough that it can be launched by a test suite. Events can be recorded into Snowplow Micro just as they can a full Snowplow pipeline. Micro then exposes an API that can be queried.

Snowplow Micro is a Docker-based solution for testing frontend and backend events in a local development environment. You need to modify GDK using the instructions below to set this up.

  1. Ensure Docker is installed and running.

  2. Install Snowplow Micro by cloning the settings in this project:

  3. Navigate to the directory with the cloned project, and start the appropriate Docker container with the following script:

    ./snowplow-micro.sh
    
  4. Update your instance's settings to enable Snowplow events and point to the Snowplow Micro collector:

    gdk psql -d gitlabhq_development
    update application_settings set snowplow_collector_hostname='localhost:9090', snowplow_enabled=true, snowplow_cookie_domain='.gitlab.com';

Snowplow Mini

Snowplow Mini is an easily-deployable, single-instance version of Snowplow.

Snowplow Mini can be used for testing frontend and backend events on a production, staging and local development environment.

For GitLab.com, we're setting up a QA and Testing environment using Snowplow Mini.

Troubleshooting

To control content security policy warnings when using an external host, you can allow or disallow them by modifying config/gitlab.yml. To allow them, add the relevant host for connect_src. For example, for https://snowplow.trx.gitlab.net:

development:
  <<: *base
  gitlab:
    content_security_policy:
      enabled: true
      directives:
        connect_src: "'self' http://localhost:* http://127.0.0.1:* ws://localhost:* wss://localhost:* ws://127.0.0.1:* https://snowplow.trx.gitlab.net/"
