User metrics definitions
We use metrics to guide prioritization and planning. By defining metrics against the kinds of behaviors that we want to drive, we can plan features and measure results against the outcomes we’re looking for. The three most important metrics we track are acquisition (of visitors), activation (visitor experiences habit creation), and retention (user remains active).
User states
People using Sourcegraph can be segmented into a number of different states, the following of which are relevant over a measured time period (for example, monthly or weekly). They are not mutually exclusive in some cases—a user can be both registered, activated and churned at the same time.
| Metric | Description | Cloud | On-prem | Pings data point | Type* |
|---|---|---|---|---|---|
| Active User | Users who performed a qualifying activation event | ✔️ | ✔️ | ✔️ | Activity |
| Registered | A user with an account on the instance | ✔️ | n/a | site_activity.MAU.RegisteredUserCount | Characteristic |
| Retained | Users who were active last period and this period | ✔️ | ✔️ | growth_statistics.RetainedUsers | MoM activity |
| Churned | Users who were active last period but not this period | ✔️ | ✔️ | growth_statistics.ChurnedUsers | MoM activity |
| Resurrected | Users who were not active last period but are active this period | ✔️ | ✔️ | growth_statistics.ResurrectedUsers | MoM activity |
| Created | Users whose account was created this period | ✔️ | ✔️ | growth_statistics.CreatedUsers | MoM activity |
| Deleted | Users whose account was deleted this period | ✔️ | ✔️ | growth_statistics.DeletedUsers | MoM activity |
*Types
- MoM Activity: Month over month usage activity descriptor
- Characteristic: a permanent user characteristic (except for creation/deletion of an account)
Registered user
Active users can be further optionally segmented into registered or non-registered users, which indicates they are logged in.
Time periods
Time periods we track:
- Daily active user (DAU)
- Weekly active user (WAU)
- Monthly active user (MAU)
The different time periods are used depending on the length of the relevant context (for example, a marketing campaign that runs for a week might track DAU while our yearly goals might track MAU.)
Engagement ratios
| Metric | Description |
|---|---|
| DAU/MAU | The ratio of average DAUs over a month to the number of MAUs in the corresponding month. If the ratio is 0.4 or 40%, the average active user used Sourcegraph 12 days per month (30 days * .4 = 12). |
| DAU/WAU | The ratio of average DAUs over a week to the number of WAUs in the corresponding week. If the ratio is 0.4 or 40%, the average active user used Sourcegraph 2.8 days per week (7 days * .4 = 2.8). |
| Saturation | The ratio of the number of specific feature users to the total number users with access to the feature. If a feature’s ratio is 0.2 or 20%, the saturation for the feature means that 1 in 5 users (in the cohort and timeframe) used the feature. |
Net Promotor Score (NPS)
Submission buckets for How likely is it that you would recommend Sourcegraph to a friend? on a scale of 0 to 10:
- 0-6: Detractor
- 7-8: Passive/Neutral
- 9-10: Promotor
NPS score = % promotors of total submissions - % detractors of total submissions
Technical Health Score (Customers)
The technical health score combines high-level, aggregated metrics in order to understand customer engagement with the product, as a means to ensure customers are receiving maximum value from Sourcegraph. We currently include the following metrics:
| Metric | Description |
|---|---|
| Adoption measured as: MAU/Total purchased seats (%) | Used as a measure of monthly adoption within a customer’s total licensed user base. |
| Usage measured as: DAU/MAU (%) | Used as a measure of overall engagement / stickiness of the platform within an account’s active users |
| # of versions behind current Sourcegraph version | Used as a measure of overall instance health |

On-Prem Instances
In each ping, instances will send a site_activity.DAUs, site_activity.WAUs, and site_activity.MAUs field which represent daily, weekly, and monthly active user counts on an instance. These numbers are taken from the event_logs table of the instance, and count the number of distinct active user IDs that executed any action on the instance in a given time period. These are sent back to us in the form of pings, which is what shows up in Looker. See the activeUsers function for the implementation and SQL query.
How are metrics calculated
Our metrics infrastructure (Looker) gets active user counts from our event_logs table (either directly or indirectly). We use the same method as on-premise for calculating active user counts, pulling from the Sourcegraph Cloud event_logs table. We track unauthenticated active users using their anonymous_user_id. This is a separate column which contains an anonymous ID, which is stored in a cookie for active users that visit Sourcegraph.com. Therefore, for all charts that track Cloud active users, unauthenticated users are included in these counts.
There are shortcomings to this. For one, when an active user converts into a registered active user, their events conducted with their anonymous ID are still in the DB, so we would count two different active users rather than a single active user. For analytics purposes in Amplitude, this is also not ideal because we are not able to connect the actions of an active user before and after they’ve converted.
