OpenTelemetry Hooks

[beeme1mr]

Overview

The OpenTelemetry team has approved and merged feature flagging into the semantic convention. Since feature flags are dynamic and affect runtime behavior, it’s important to collect relevant feature flag telemetry signals. This can be used to determine the impact a feature has on a request, enabling enhanced observability use cases, such as A/B testing or progressive feature releases.

OpenFeature hooks should be created in each supported language.

Requirements

Create an OTel hook for the following languages:

• [x] OTel Hook for Node.JS
• [x] OTel Hook for Java
• [x] OTel Hook for .NET
• [x] OTel Hook for Go
• [ ] OTel Hook for Python
• [x] OTel Hook for PHP
• [ ] OTel Hook for Ruby
