2 years ago Please check https://www.envoyproxy.io/docs/envoy/latest/api-v3/type/tracing/v3/custom_tag.proto and related docs. I think if you specify the route name as a custom tag, it will be added since route name is stored in stream_info:

Title: Add the route name to trace data
Description:
I would like to group and filter traces by route name, since that will be a key dimension for us; right now there's no good way of doing it. The route name is available in the access logs, but we sample those heavily and mostly rely on traces, which integrate much better with the rest of our observability data.
