# 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
- 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. Manual-instrument [Go agent](https://github.com/tetratelabs/go2sky) in SkyWalking format.
1. Istio telemetry format
1. Envoy gRPC Access Log Service (ALS) format in Istio controlled service mesh
1. Envoy Metrics Service format.
1. Zipkin v1/v2 format.
1. Jaeger gRPC format.
