From 5.x, it evolved to the fully functional [Application Performance Management](https://en.wikipedia.org/wiki/Application_performance_management) system. It is used for tracing, monitoring, diagnose distributed systems, especially based on microservices, cloud native and container, including: - Distributed tracing and context propagation - Application, instance, service metrics analysis - Root cause analysis - Application topology map analysis - Application and service dependency analysis - Slow service detected - Performance optimization # Core features - Multiple languages instrumentation agent or libraries - Native Java auto instrumentation agent. Trace and monitor your cluster without changing any source codes - Community instrumentation agent or libraries * [.NET Core](https://github.com/OpenSkywalking/skywalking-netcore) * [Node.js](https://github.com/OpenSkywalking/skywalking-nodejs) - Multiple storage backends: ElasticSearch, H2 - [OpenTracing](http://opentracing.io/) compatible - Native Java auto instrumentation agent could work with OpenTracing APIs in the same context - Lightweight and powerful backend aggregation and analysis capabilities - Modern and cool Web UI - Log integration - Alarm for slow or unstable(low SLA) application, instance and service - [**Incubating**] Support accepting other tracer data formats. - Zipkin JSON, Thrift, Protobuf v1 and v2 formats, powered by [OpenZipkin](https://github.com/openzipkin/zipkin) libs - Jaeger in [Zipkin Thrift or JSON v1/v2 formats](https://github.com/jaegertracing/jaeger#backwards-compatibility-with-zipkin) # Document - [Documents in English](docs/README.md) - [Documents in Chinese](docs/README_ZH.md) # 5.x Architecture # Code of conduct This project adheres to the Contributor Covenant [code of conduct](CODE_OF_CONDUCT.md).
