@Razi Kheir to get both sides of the tracing propogating you need to add RequestTracing filters to both the server and client sides. This will not send the traffic to Jaeger by itself - just decorate the messages with the correct headers. We typically attach the trace information to logs which are then send to splunk/elk. you can also use a service mesh to send them to Jaeger etc.

As to your other q: AFAIK it's not possible to decorate traffic outside of your code because there is no way to tie up the incoming and outgoing calls. We generally create standardised "stacks" of filters (ie just a filter!) for both servers and clients that takes care of this ancillary stuff for us - so we'd combine metrics, tracing, logging, catch all error handling, security etc....
