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. Read Apache SkyWalking: Use Profiling to Fix the Blind Spot of Distributed Tracing.
  • 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 1. Java, .NET Core, NodeJS, PHP, and Python auto-instrument agents. 1. Go agent. 1. LUA agent especially for Nginx, OpenResty. 1. Service Mesh Observability. Support Mixer telemetry. Recommend to use Envoy Access Log Service (ALS) for better performance, first introduced at KubeCon 2019. 1. Metrics system, including Prometheus, OpenTelemetry, Spring Sleuth(Micrometer). 1. Browser application performance, including metrics and error logs. 1. 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.
