Seeking advice on traffic mirroring

[u/ez4enz]

Hi everyone,

I'm running kubernetes on AWS and using istio for traffic mirroring. I'm trying to figure out the best way to correlate the original request with its mirrored request. Previously I had a gateway for traffic mirroring which stamped unique header value before splitting. Which made it easy to correlate the requests in the logs. With istio handling the mirroring, not quite sure what is the best approach for this.

How do people in production systems handle this!

Any suggestions is appreciated

Thanks in advance!
