Metric groups

Overview

This topic explains what metric groups are and when to use them. A metric group is a reusable list of metrics you can use to standardize metrics across multiple flags or experiments.

For example, if you have a standard user sign-up flow, you could create four metrics that track customers clicking the sign up button, entering their personal information, adding payment information, and clicking the submit button. By combining these four metrics into a funnel metric group, you can then attach that group to all of your sign-up funnel experiments, ensuring you're tracking the correct metrics for each step within each funnel.

You can view your metric groups from the Metrics list:

Metric group types

There are two types of metric groups: funnel metric groups and standard metric groups.

Funnel metric groups

Funnel metric groups are for use with funnel optimization experiments. A "funnel" is a marketing model that describes a customer's journey through your purchasing or conversion cycle, typically from the awareness stage to the purchasing stage. LaunchDarkly's funnel optimization experiments use multiple metrics to track the performance of each of the steps in your funnel over time.

The order of metrics within funnel metric groups affects how LaunchDarkly analyzes the metrics. When you create a funnel metric group, each metric should measure a required step in the user journey. Users should not be able to skip any steps the funnel group is measuring, or take any steps out of order. Doing so will skew your experiment results.

To include a metric in a funnel metric group, the metric must:

• have a custom conversion binary, clicked or tapped, or page viewed type
• use the "Occurrence" measurement method

You cannot include custom numeric metrics or custom conversion count metrics in a funnel metric group, and you cannot include any metrics that use the "Count" or "Value/size" measurement method in a funnel metric group.

To learn more, read Creating funnel experiments.

You cannot use funnel metric groups in feature change experiments. Instead, use a standard metric group.

Standard metric groups

Standard metric groups are for use with feature change experiments and guarded rollouts. Metrics in standard metric groups can appear in any order. To learn more, read Creating feature change experiments and Guarded rollouts.
