Metric Family

Making it easier to manage metric variant.

Metric Families let you create metric variants as child metrics of a parent metric. When you update a parent metric, the changes cascade automatically to its child metrics, keeping all related metric definitions consistent. Use a Metric Family to manage a large catalog of near-identical metric variants without editing each one manually.

Child metrics of SUM and COUNT parent metrics support these modifiable configs:

  • Add metric source filter
  • Outlier Management
  • Variance Reduction
  • Cohorts and Delayed Data

Create a child metric

To create a child metric, select the Create Child Metric option in the dropdown menu in the top right corner of a metric.

Creating a child metric

You can track the child metrics for a given parent metric using the metric family icon in the top right.

Deleting and archiving

When you delete or archive a parent metric, Statsig deletes or archives all of its child metrics as well. When you re-enable the parent, Statsig automatically restores those child metrics. You can't restore child metrics disabled through the parent individually; you can only re-enable them by restoring the parent metric.

Metric deletion confirmation message

If you delete or archive a child metric independently of its parent, you can restore the child metric on its own. The restored child metric returns as a standalone metric without its original parent-child relationship.

In experiments

When you select a Parent Metric in Experiment setup, Statsig adds all of its child metrics as well. You can remove any metrics you don’t need in the experiment.

Adding parent metric to an experiment will add all child metrics with it
