AI Technical Summary

Technical Problem

Existing link tracing technologies suffer from problems such as high overhead for full data collection, difficulty in tracing NAT scenarios, and disconnect between application and network monitoring in cloud-native and load-balanced scenarios, making troubleshooting difficult.

Method used

By collecting predetermined process information of the target system, identifying the running status, dynamically enabling application layer tracing, and combining NAT data with five-tuple information, full-link tracing data is generated to realize the association between application layer call information and network transmission path.

Benefits of technology

It reduces system overhead, solves the link breakage problem in NAT scenarios, improves troubleshooting efficiency, and achieves integrated observability of applications and networks.

Abstract

The application relates to a link tracking method, device, medium and computer program product. The method comprises: collecting predetermined process information of a target system, and collecting application link data of an application request in the target system when an abnormal running state is identified, the application link data comprising a tracking identifier and a span identifier; stopping the collection of the application link data when the running state returns to normal; collecting network link data and network address translation (NAT) data of the target system, correlating five-tuple information before and after NAT according to the NAT data, and extracting the network link data of the five-tuple before and after NAT; collecting application network correlation data in the target system, the application network correlation data representing a mapping relationship between the tracking identifier, the span identifier in an application layer message and the five-tuple information in a transport layer message; and correlating the collected application link data and the extracted network link data based on the application network correlation data, to generate full-link tracking data comprising application call information and a network transmission path.
