instead of having function definition changed everywhere with 2 alternatives, can you try testing adding span to RGWSimpleRequest https://github.com/ideepika/ceph/blob/jaeger-rebase-8.0/src/rgw/rgw_rest_client.h#L10:L10

+{
+  Span span = tracer.child_span("rgw_rest_swift.cc RGWDeleteObj_ObjStore_SWIFT::verify_permission", parent_span);


you mentioned you were going to try using a global tracer, can you explain your approach here?

@ideepika the tracer is global, but the spans are not, each "Root" span denotes a new client request and that "Root" span will contain its serveral follow_up spans and child spans.
In the above example I m creating a new child span, parent_span is the span created in the function which is calling this function RGWDeleteObj_ObjStore_SWIFT::verify_permission

@suab321321 I understand that, my question is : is it important to pass the tracer to the function, or are you keeping the tracer globally unique for rgw?

@ideepika yes it is mandatory to pass the tracer as an argument, even if I make the tracer an extern and use this as global tracer, but I wont be able to make the Span an extern variable.I understand that by making and tracer and Span global I dont have to pass the variable as argument which in turn will prevent the creating of overloaded function, but the span variable is an issue here

Hey @suab321321 !
Nice work till now, a few suggestions:

can you cleanup commits, with eliminating changes which are unrelated to jaeger.
can you also add a screenshot of jaeger trace with each commit addition, that way it would be easier to follow your code updates.
we can test the span traversal using req_state as we discuss, since that would change a lot of this code, I would rather help you out in that first, let's keep review stalled uptil then.

can you remove non-jaeger changes in the further cleanups, it would make work easier for reviewer, hence better focus on feedback.

are these changes part of your code? If not can you clean them up?
