Key features
Collect traces, metrics, and logs through shared APIs and SDKs
The repository hosts the Java OpenTelemetry API and SDK, including stable artifacts for traces, metrics, logs, context, and related components.
Sources: [2]
Align artifact versions with BOMs and export telemetry through OTLP
The README strongly recommends BOMs to keep artifact versions synchronized, and the repository includes OTLP and other exporters.
Sources: [2]
Best fit
Fits manual and library instrumentation in Java services
It is the core building block when applications or libraries need programmatic control over spans, metrics, logs, and propagation.
