# Abstract
**SkyWalking** is an open source APM system, including monitoring, tracing, diagnosing capabilities for distributed system
in Cloud Native architecture.
The core features are following.
- Service, service instance, endpoint metrics analysis
- Root cause analysis. Profile the code on the runtime.
- Service topology map analysis
- Service, service instance and endpoint dependency analysis
- Slow services and endpoints detected
- Performance optimization
- Distributed tracing and context propagation
- Database access metrics. Detect slow database access statements(including SQL statements).
- Alarm
SkyWalking supports to collect telemetry (traces and metrics) data from multiple sources
and multiple formats,
including
1. Java, [.NET Core](https://github.com/SkyAPM/SkyAPM-dotnet), [NodeJS](https://github.com/SkyAPM/SkyAPM-nodejs) and [PHP](https://github.com/SkyAPM/SkyAPM-php-sdk) auto-instrument agents in SkyWalking format
1. [Go agent](https://github.com/tetratelabs/go2sky).
1. [LUA agent](https://github.com/apache/skywalking-nginx-lua), especially for Nginx, OpenResty.
1. Envoy gRPC Access Log Service (ALS) format in Istio controlled service mesh.
1. Istio telemetry format.
1. Envoy Metrics Service format.
1. Zipkin v1/v2 format.
1. Jaeger gRPC format.
