Metrics

Metrics track flag behavior over time when an experiment is running. The data generated from experiments gives you more insight into the impact of a particular flag. To learn more, read Metrics.

Using the metrics API, you can create, delete, and manage metrics.

Are you importing metric events?

If you want to import metric events into LaunchDarkly from an existing data source, use the metric import API. To learn more, read Importing metric events.

Metric keys and event keys are different

LaunchDarkly automatically generates a metric key when you create a metric. You can use the metric key to identify the metric in API calls.

Custom conversion/binary and custom numeric metrics also require an event key. You can set the event key to anything you want. Adding this event key to your codebase lets your SDK track actions customers take in your app as events. To learn more, read Sending custom events.
