Creating metrics

Overview

This topic explains how to create, edit, and delete metrics, and how select which metric type to use with LaunchDarkly features, such as experiments and guarded rollouts.

Choose a metric type

You should choose a metric type that correctly measures the effect of a change on your customers or codebase. If you are unsure of what metric type to use, it may be helpful to begin by determining what kind of data you are trying to measure. For examples of common metrics and how to configure them, read Example metrics.

This table includes examples of different kinds of data you can measure with different metric types, and common randomization unit context kind mappings:

When you create a metric, you must decide how you want to handle its metric and unit analysis. To learn more, read Metric analysis.

Edit metrics

To edit a metric:

1. Navigate to the Metrics list.
2. Click the title of the metric you want to edit. The metric details screen opens.
3. Click Edit metric in the "Event information" section. You can edit a metric's key, unit of measure, success criteria, randomization units, and tags.
4. Click Save metric.

Delete metrics

You should delete a metric only when you are sure you will no longer use it.

To delete a metric:

1. Navigate to the Metrics list.
2. Click the title of the metric you want to delete. The metric details screen opens.
3. Click Delete.

This metric is now deleted permanently across all environments in the project.
