Feature flag settings
The Feature Flags tab in Project Settings is where configuration changes are made to the feature flag change sources in your project. Additionally, you can manage the mapping of Sleuth environments to your LaunchDarkly environments.
Feature flag change sources track changes made by the feature flags deployed in your application and that have been integrated with Sleuth. Changes are associated to code deployed in your environments. You can also:
- Capture the flag changes being made
- Generate Slack notifications of a flag change
- Link your flag changes to deployed code
To edit feature flag change sources, click the edit dropdown in the Actions column then select **Edit **to view the Edit Feature Flag screen (shown below).
Make changes as needed to your feature flags. Here you can:
- Change the name of the feature flag change source, which is shown in the Feature Flags section of the sidebar.
- Select the LaunchDarkly project that contains the feature flags you want to track in Sleuth.
- Select the LaunchDarkly environment you want to track with this feature flag change source. Only the environments that are contained in the LaunchDarkly project selected above will be displayed. If you enable the _Map separate LaunchDarkly environments to Sleuth environments _checkbox, you can map multiple LaunchDarkly environments to your Sleuth environment (see next section).
- Select code deployments shown in the _Used by code deployments _list to link your feature flag changes to. Deployed code that contain feature flags that have been configured in the LaunchDarkly project and environment(s) configured above will be included in the data displayed in the Dashboard.
To correctly attribute feature flag changes to the right Sleuth environment you must map your LaunchDarkly environments to your Sleuth environments. This feature is only available if you have two or more Sleuth environments (and two or more LaunchDarkly environments).
Additional configuration options allow you to fine-tune the behavior of Sleuth when it detects deploys via your feature flag change sources.
Selecting this checkbox lets Sleuth associate impact information with feature flags. If unchecked Impact measurements won't be attributed to changes made via feature flags.
Selecting this checkbox displays the feature flags in the project dashboard, along with the associated stats and graphs in the deploy cards.
