Metric Family

Managing a large catalog of metrics that are slight variants of one another can be difficult. A common challenge is ensuring that each metric variant inherits the same changes when the metrics need to be updated.

Metric Families let you create metric variants as child metrics of a parent metric. When you update a parent metric, the changes automatically cascade to its child metrics, keeping all related metric definitions consistent.

The table below lists all supported metric types along with the modifications that can be applied to their child metrics.

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.

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

Deleting and archiving

When a parent metric is deleted or archived, all of its child metrics are deleted or archived as well. Re-enabling the parent 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.

If a child metric is deleted or archived independently of its parent, it can be restored on its own, but it returns as a standalone metric without its original parent-child relationship.

In experiments

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