# Abstract
**SkyWalking** started as a distributed tracing system in 2015. 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
