wu-sheng opened a new issue #4634: Implement Extension Header Item in java agent URL: https://github.com/apache/skywalking/issues/4634 ### Extension Header Item Extension header item is designed for the advanced features. It provides the interaction capabilities between the agents deployed in upstream and downstream services. * Header Name: `sw8-x` * Header Value: Split by `-`. The fields are extendable. #### Values The current value includes fields. 1. Tracing Mode. empty, 0 or 1. empty or 0 is default. 1 represents all spans generated in this context should skip analysis, `spanObject#skipAnalysis=true`. This context should be propagated to upstream in the default, unless it is changed in the tracing process. Link, https://github.com/apache/skywalking/blob/master/docs/en/protocols/Skywalking-Cross-Process-Propagation-Headers-Protocol-v3.md#extension-header-item @arugal Once this implements in the Java and go2sky, we should release a new version and enhance the MOSN filter again. If you have any question about this use case, we could discuss on the bi-weekly meeting directly.
