Apache SkyWalking

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

Java, .NET Core, NodeJS, PHP, and Python auto-instrument agents.
Go and C++ SDKs.
LUA agent especially for Nginx, OpenResty and Apache APISIX.
Browser agent.
Service Mesh Observability. Control panel and data panel.
Metrics system, including Prometheus, OpenTelemetry, Spring Sleuth(Micrometer), Zabbix.
Logs.
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.
