If you need an easier way to bring observability to remote JVM-based applications and workflows that isn't easily satisfied by an SDK feature or via instrumentation, this project is hopefully for you. ## Provided Libraries | Status* | Library | |---------|-------------------------------------------------------------------| | beta | [AWS Resources](./aws-resources/README.md) | | stable | [AWS X-Ray SDK Support](./aws-xray/README.md) | | alpha | [AWS X-Ray Propagator](./aws-xray-propagator/README.md) | | alpha | [Baggage Processors](./baggage-processor/README.md) | | alpha | [zstd Compressor](./compressors/compressor-zstd/README.md) | | alpha | [Consistent Sampling](./consistent-sampling/README.md) | | alpha | [Disk Buffering](./disk-buffering/README.md) | | alpha | [GCP Authentication Extension](./gcp-auth-extension/README.md) | | beta | [GCP Resources](./gcp-resources/README.md) | | beta | [Inferred Spans](./inferred-spans/README.md) | | alpha | [JFR Connection](./jfr-connection/README.md) | | alpha | [JFR Events](./jfr-events/README.md) | | alpha | [JMX Metric Gatherer](./jmx-metrics/README.md) | | alpha | [JMX Metric Scraper](./jmx-scraper/README.md) | | alpha | [Kafka Support](./kafka-exporter/README.md) | | alpha | [OpenTelemetry Maven Extension](./maven-extension/README.md) | | alpha | [Micrometer MeterProvider](./micrometer-meter-provider/README.md) | | alpha | [No-Op API](./noop-api/README.md) | | alpha | [Intercept and Process Signals Globally](./processors/README.md) | | alpha | [Prometheus Client Bridge](./prometheus-client-bridge/README.md) | | alpha | [Resource Providers](./resource-providers/README.md) | | alpha | [Runtime Attach](./runtime-attach/README.md) | | alpha | [Samplers](./samplers/README.md) | | beta | [Span Stacktrace Capture](./span-stacktrace/README.md) | \* `alpha`, `beta` and `stable` are currently used to denote library status per [otep 0232](https://github.com/open-telemetry/oteps/blob/main/text/0232-maturity-of-otel.md). To reach stable status, the library needs to have stable APIs, stable semantic conventions, and be production ready. On reaching stable status, the `otel.stable` value in `gradle.properties` should be set to `true`. Note that currently all the libraries are released together with the version of this repo, so breaking changes (after stable status is reached) would bump the major version of all libraries together. This could get complicated so `stable` has a high bar. ## Getting Started ```bash # Apply formatting $ ./gradlew spotlessApply # Build the complete project $ ./gradlew build # Run integration tests $ ./gradlew integrationTest # Clean artifacts $ ./gradlew clean ``` ## Contributing The Java Contrib project was initially formed to provide methods of easy remote JMX metric gathering and reporting, which is actively in development. If you have an idea for a similar use case in the metrics, traces, or logging domain we would be very interested in supporting it. Please [open an issue](https://github.com/open-telemetry/opentelemetry-java-contrib/issues/new/choose) to share your idea or suggestion. PRs are always welcome and greatly appreciated, but for larger functional changes a pre-coding introduction can be helpful to ensure this is the correct place and that active or conflicting efforts don't exist. ### Maintainers - [Jack Berg](https://github.com/jack-berg), New Relic - [Jason Plumb](https://github.com/breedx-splk), Splunk - [Lauri Tulmin](https://github.com/laurit), Splunk - [Trask Stalnaker](https://github.com/trask), Microsoft For more information about the maintainer role, see the [community repository](https://github.com/open-telemetry/community/blob/main/guides/contributor/membership.md#maintainer). ### Approvers - [John Watson](https://github.com/jkwatson), Verta.ai For more information about the approver role, see the [community repository](https://github.com/open-telemetry/community/blob/main/guides/contributor/membership.md#approver). ### Triagers - All [component owners](https://github.com/open-telemetry/opentelemetry-java-contrib/blob/main/.github/component_owners.yml) are given Triager permissions to this repository.
