Apache SkyWalking

SkyWalking: an APM(application performance monitor) system, especially designed for microservices, cloud native and container-based (Docker, Kubernetes, Mesos) architectures.

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
Browser performance monitoring

SkyWalking supports to collect telemetry (traces and metrics) data from multiple sources and multiple formats, including

Java, .NET Core, NodeJS, PHP, and Python auto-instrument agents.
Go and C++ SDKs.
LUA agent especially for Nginx, OpenResty.
Service Mesh Observability. Control panel and data panel.
Metrics system, including Prometheus, OpenTelemetry, Spring Sleuth(Micrometer).
Browser application performance, including metrics and error logs.
Zipkin v1/v2 and Jaeger gRPC format with limited topology and metrics analysis.(Experimental).

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.
