Using the Datadog events integration

Overview

This topic explains how to configure and use the LaunchDarkly Datadog events integration.

The Datadog integration lets you set up Datadog Events to receive any activity from LaunchDarkly. When something changes, such as a feature flag updates or a new account member is added to LaunchDarkly, LaunchDarkly sends an event to Datadog. Use this integration to correlate and understand how changes to your features in LaunchDarkly impact your app and infrastructure metrics.

Filtering the events you send to Datadog

By default, LaunchDarkly sends events to Datadog for changes made to any project, environment, feature flag, and more. If you have a more limited use case for using the integration, or you wish to restrict which data you send to Datadog, you can filter which events LaunchDarkly sends.

To filter events, write a policy using the same syntax as our custom roles feature to filter the events sent to Datadog.

For more information about writing policies, read Policies in custom roles.

For example, if you only want to receive an event when a change is made to one of the feature flags in your testing environment, you can add the following policy to your events stream:

[
  {
    "effect": "allow",
    "actions": ["*"],
    "resources": ["proj/*:env/your-test-environment:flag/*"]
  }
]
COPY

To add a custom filter:

1. Navigate to the Integrations page.
2. Find the integration you wish to modify and click Edit integration configuration. The "Edit Datadog configuration" panel appears.

3. Click Advanced editor. The Advanced editor appears.
4. Enter your custom policy.

5. Click Save configuration.
6. Verify that LaunchDarkly is sending a customized set of events by viewing the events in your Datadog dashboard.
