Tracing AMQP Workflow about jaeger-php

[jukylin]

Does amqp implement Distributed Tracing?

[Mulkave]

Not with PHP, no. There is a Go package for that though https://github.com/opentracing-contrib/go-amqp not sure if it helps (new to this realm, sorry).

On the other hand, it is not necessary to track within AMQP, what matters is to trace the spans in the services (it's alright to skip AMQP for tracing).

Would that work? i.e. if we were to pass the SpanContext through message headers of AMQP somehow?

I think you need to inject SpanContext to message body. Like this： Service A： $tracer->inject($serverSpan->getContext(), Formats\TEXT_MAP, $amqpMsg) and Service C : $tracer->extract(Formats\TEXT_MAP, $amqpMsg)
