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. 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

Java, .NET Core, NodeJS, PHP, and Python auto-instrument agents.
Go agent.
LUA agent especially for Nginx, OpenResty.
Service Mesh Observability. Support Istio telemetry metrics. Recommend to use Envoy Access Log Service (ALS) for better performance, first introduced at KubeCon 2019.
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.
