-# 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.
+SkyWalking-Java: The Java Agent for Apache SkyWalking, which provides the native tracing/metrics/logging abilities for Python project.
 
-- 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
-- Browser performance monitoring
-- Infrastructure(VM, network, disk etc.) monitoring
-- Collaboration across metrics, traces, and logs

-
-SkyWalking supports to collect telemetry (metrics, traces, and logs) data from multiple sources
-and multiple formats,
-including
-1. Java, .NET Core, NodeJS, PHP, and Python auto-instrument agents.
-1. Go and C++ SDKs.
-1. LUA agent especially for Nginx, OpenResty and Apache APISIX.
-1. Browser agent.
-1. Service Mesh Observability. Control panel and data panel. 
-1. Metrics system, including Prometheus, OpenTelemetry, Spring Sleuth(Micrometer), Zabbix.
-1. Logs.
-1. Zipkin v1/v2 trace.(No Analysis)
-
-SkyWalking OAP is using the STAM(Streaming Topology Analysis Method) to analysis topology in the tracing based agent scenario 
-for better performance. Read [the paper of STAM](https://wu-sheng.github.io/STAM/) for more details.
+SkyWalking: an APM(application performance monitor) system, especially designed for microservices, cloud native and container-based (Docker, Kubernetes, Mesos) architectures.
