OpenTelemetry in client-side SDKs

Overview

This topic explains how to enable OpenTelemetry in client-side SDKs, using the LaunchDarkly observability plugins. OpenTelemetry (OTel) is an open source observability framework and toolkit designed to create and manage telemetry data such as traces, metrics, and logs.

Viewing OpenTelemetry data in LaunchDarkly

In the LaunchDarkly UI, OpenTelemetry data is used in the observability, Experimentation, feature monitoring, and guarded rollouts features.

When LaunchDarkly receives OpenTelemetry trace data, it processes and converts this data into events that LaunchDarkly metrics track over time. In particular, when you are working with client-side SDKs, the LaunchDarkly observability SDKs provide error monitoring and metric collection for errors, web vitals, and document loading in your browser application.

Sending OpenTelemetry data to LaunchDarkly

When you use one of the LaunchDarkly client-side SDKs, LaunchDarkly automatically ingests OTel data if you are using one of the observability SDKs. These are implemented as plugins that you can configure as part of initializing the client-side SDK.

The SDKs send this data to LaunchDarkly at the following endpoints:

• https://otel.observability.app.launchdarkly.com/v1/traces
• https://otel.observability.app.launchdarkly.com/v1/logs
• https://otel.observability.app.launchdarkly.com/v1/metrics

You may need to update your infrastructure to make sure the SDK can reach this domain. To learn more, read Accessing LaunchDarkly by domain.
