A method for solving two-stage deployment link tracing

This method provides a two-stage deployment link tracing solution, which includes: obtaining link data from the called side system and determining whether the link data is cross regional data sent from the calling side system to the called side system; When the link data is cross regional data sent from the calling side system to the called side system, obtain a tracking identifier from the link data; Obtain the first cascade data from the calling side system based on the tracking identifier, and obtain the second cascade data from the called side system based on the tracking identifier; Process the first cascade data and the second cascade data to obtain tracking data. In this way, cross link data sent from the calling side system to the called side system can be traced, achieving complete data link tracking, thereby facilitating fault location, performance tuning, and user behavior analysis.
