What is Link Tracking Skywarking
Link Tracing is a technique for tracking request paths and performance in distributed systems. SkyWalking is an open source APM (Application Performance Monitoring) system that provides link tracking functionality.
SkyWalking's link tracking captures and records each component that the request passes through by embedding lightweight agents in different components in the distributed system. It connects these components through a unique cross-request identifier to form a complete request chain. In this way, developers can understand exactly how requests flow through the system, and analyze and optimize the performance of each component.
Link tracing can help developers quickly locate performance problems and faults in the system. By analyzing link trace data, the following information can be obtained:
- Request path: You can clearly see where the request starts, which components it passes through, and where it ends up. This is especially important for complex distributed systems.
- Time-consuming analysis: You can count the processing time of each component to find out where the performance bottleneck is. Developers can optimize based on this information to improve the response speed of the system.
- Abnormal location: If a request has an error or anomaly in the link, the link tracking data can be used to quickly locate specific components and codes for troubleshooting and repair.
SkyWalking provides rich link tracking functions and supports multiple programming languages and frameworks. It also provides a visual interface for developers to view and analyze link tracking data. By using SkyWalking, developers can better understand and manage the performance of distributed systems.
