The telemetry library implements a minimal OpenTelemetry tracing client that is compatible with the OTEL data model but not compliant with the OTEL client specification.

This was developed to avoid taking a dependency on the official OpenTelemetry PHP client, which was deemed too complex to integrate with MediaWiki (T340552).

telemetry requires a PSR-3 logger, a PSR-18 HTTP client and a PSR-17 HTTP factory.
