Changelog

2.3.0-beta.1 (2024-04-12)

Update to OpenTelemetry 2.2.0
- The resource providers for Google Cloud and AWS are not enabled by default anymore. You can enable them using OTEL_RESOURCE_PROVIDERS_AWS_ENABLED=true and OTEL_RESOURCE_PROVIDERS_GCP_ENABLED=true.
- Jetty is now supported in Spring Boot 3.2.

Update to OpenTelemetry 2.1.0
- Actuator instrumentation has been disabled by default. You can enable using OTEL_INSTRUMENTATION_SPRING_BOOT_ACTUATOR_AUTOCONFIGURE_ENABLED=true or -Dotel.instrumentation.spring-boot-actuator-autoconfigure.enabled=true.

Update to OpenTelemetry 2.0.0
- Many Breaking Change, most notably:
  - The default OTLP protocol has been changed from grpc to http/protobuf in order to align with the specification. You can switch to the grpc protocol using OTEL_EXPORTER_OTLP_PROTOCOL=grpc or -Dotel.exporter.otlp.protocol=grpc.
  - Micrometer metric bridge has been disabled by default. You can enable it using OTEL_INSTRUMENTATION_MICROMETER_ENABLED=true or -Dotel.instrumentation.micrometer.enabled=true.
- Stable JVM semantic conventions are now emitted by default - but this was already the case in 0.32.0-beta.1 (via opt-in), so no change here.
(Informational, not related to this release) Spring Boot 3.2 is supported, except for Jetty (see compatibility matrix).
The following GRAFANA_* environment variables are now deprecated and will be removed in a future release. Please use OTEL_* environment variables instead (in the spirit of making it easy to migrate away from this distribution).
- GRAFANA_OTLP_DEBUG_LOGGING and GRAFANA_OTLP_LOGGING_EXPORTER_ENABLED (details)
- GRAFANA_CLOUD_INSTANCE_ID, GRAFANA_CLOUD_ZONE, and GRAFANA_CLOUD_API_KEY (details)

Update to OpenTelemetry 1.32.0
Breaking Change: Use new JVM semantic conventions
Breaking Change: Use telemetry.distro.name = grafana-opentelemetry-java and telemetry.distro.version = 0.32.0-beta.1 to identify this distribution instead of telemetry.sdk.name = grafana-opentelemetry-java and telemetry.sdk.version = 0.32.0 (for reference: from now on telemetry.sdk.name = opentelemetry and telemetry.sdk.version = 1.32.0.

This is the first public preview release of this distribution which is released together with the public release of Grafana Cloud Application Observability.
This release is based on OpenTelemetry 1.31.0 - so the version number becomes 0.31.0 (we'll switch to 1.x.y with the first GA release).
No functional changes.

Add resource detectors for Google Cloud and AWS - mainly for Kubernetes monitoring.
Add ability to drop metrics that are not needed for Application Observability (docs).
Rename grafana cloud environment variables GRAFANA_OTLP_CLOUD_* to GRAFANA_CLOUD_*.
