Flagsmith

Overview

Flagsmith facilitates feature management across web, mobile, and server side applications. The Datadog Flagsmith integration enables you to view information about flag changes directly within Datadog.

Flagsmith provides the following integrations with Datadog:

Events integration

All flag change events are sent to Datadog. These events are tagged with the environment they were changed in.

Feature flag tracking integration

Flagsmith’s feature flag tracking integration enriches your RUM data with your feature flags to provide visibility into performance monitoring and behavioral changes. Determine which users are shown a user experience and if it is negatively affecting the user’s performance.

Dashboard widget

Flagsmith’s dashboard widget lets you view your Flagsmith Flags and Audit Logs directly in Datadog.

Setup

In the Flagsmith Dashboard, select the Integrations Menu and then add the Datadog Integration. Enter your Datadog API Key. For Base URL, enter https://api.datadoghq.com if you are using the US Datadog site, or https://api.datadoghq.eu if you are using the EU Datadog site.

    },
