Migrating existing tracking to internal event tracking

GitLab Internal Events Tracking exposes a unified API on top of the deprecated Snowplow and Redis/RedisHLL event tracking options.

This page describes how you can switch from one of the previous methods to using Internal Events Tracking.

Tracking events directly via Snowplow, Redis/RedisHLL is deprecated but won’t be removed in the foreseeable future. While we encourage you to migrate to Internal Event tracking the deprecated methods will continue to work for existing events and metrics.

Migrating from existing Snowplow tracking

If you are already tracking events in Snowplow, you can also start collecting metrics from self-managed instances by switching to Internal Events Tracking.

The event triggered by Internal Events has some special properties compared to previously tracking with Snowplow directly:

  1. The label, property and value attributes are not used within Internal Events and are always empty.
  2. The category is automatically set to InternalEventTracking

Please make sure that you are okay with this change before you migrate and dashboards are changed accordingly.


If you are already tracking Snowplow events using Gitlab::Tracking.event and you want to migrate to Internal Events Tracking you might start with something like this:

Gitlab::Tracking.event(name, 'ci_templates_unique', namespace: namespace,
                               project: project, context: [context], user: user, label: label)

The code above can be replaced by this:

Gitlab::InternalEvents.track_event('ci_templates_unique', namespace: namespace, project: project, user: user)

In addition, you have to create definitions for the metrics that you would like to track.

To generate metric definitions, you can use the generator like this:

bin/rails g gitlab:analytics:internal_events \
  --time_frames=7d 28d\
  --group=project_management \
  --stage=plan \
  --section=dev \
  --event=ci_templates_unique \
  --unique=user.id \


If you are using the Tracking mixin in the Vue component, you can replace it with the InternalEvents mixin.

For example, if your current Vue component look like this:

import Tracking from '~/tracking';
mixins: [Tracking.mixin()]
this.track('some_label', options)

After converting it to Internal Events Tracking, it should look like this:

import { InternalEvents } from '~/tracking';
mixins: [InternalEvents.mixin()]

You can use this MR as an example. It migrates the devops_adoption_app component to use Internal Events Tracking.

If you are using data-track-action in the component, you have to change it to data-event-tracking to migrate to Internal Events Tracking.

For example, if a button is defined like this:


This can be converted to Internal Events Tracking like this:


Notice that we just need action to pass in the data-event-tracking attribute which will be passed to both Snowplow and RedisHLL.

Migrating from tracking with RedisHLL


If you are currently tracking a metric in RedisHLL like this:

  Gitlab::UsageDataCounters::HLLRedisCounter.track_event(:git_write_action, values: current_user.id)

To start using Internal Events Tracking, follow these steps:

  1. Create an event definition that describes git_write_action (guide).
  2. Find metric definitions that list git_write_action in the events section (20210216182041_action_monthly_active_users_git_write.yml and 20210216184045_git_write_action_weekly.yml).
  3. Change the data_source from redis_hll to internal_events in the metric definition files.
  4. Add an events section to both metric definition files.

       - name: git_write_action
         unique: user.id

    Use project.id or namespace.id instead of user.id if your metric is counting something other than unique users.

  5. Call InternalEvents.tract_event instead of HLLRedisCounter.track_event:

     - Gitlab::UsageDataCounters::HLLRedisCounter.track_event(:git_write_action, values: current_user.id)
     + Gitlab::InternalEvents.track_event('project_created', user: current_user)
  6. Optional. Add additional values to the event. You typically want to add project and namespace as it is useful information to have in the data warehouse.

     - Gitlab::UsageDataCounters::HLLRedisCounter.track_event(:git_write_action, values: current_user.id)
     + Gitlab::InternalEvents.track_event('project_created', user: current_user, project: project, namespace: namespace)
  7. Update your test to use the internal event tracking shared example.


If you are calling trackRedisHllUserEvent in the frontend to track the frontend event, you can convert this to Internal events by using mixin, raw JavaScript or data tracking attribute,

Quick start guide has example for each methods.
