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
• 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.
2. Go and C++ SDKs.
3. LUA agent especially for Nginx, OpenResty and Apache APISIX.
4. Browser agent.
5. Service Mesh Observability. Control panel and data panel.
6. Metrics system, including Prometheus, OpenTelemetry, Spring Sleuth(Micrometer), Zabbix.
7. Logs.
8. 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 for more details.

• Blog about Use Profiling to Fix the Blind Spot of Distributed Tracing
• Blog about observing Istio + Envoy service mesh with ALS solution.
• Blog about observing Istio + Envoy service mesh with ALS Metadata-Exchange mechanism (in VMs and / or Kubernetes).
• 官方文档
• 中文存根
• opentracing
• OAL扩展
• 环境搭建
• 基础概念
  • Skywalking中实现了OpenTracing中的Trace、Span、Tags、Logs等核心概念，不同之处是在Trace级别和Span级别之间加了一个Segment概念，用于表示一个服务实例内的Span集合
