Overall feature includes both Tracing Framework and Collector #6750
Tracing collector #7352

Prototype Tracing framework
#7026

[Meta Tracing Framework] #7542

• [Distributed Tracing] Add support to use trace propagated from client. #9465
• [Tracing Instrumentation] Add instrumentation at Rest Layer #8552
• [Tracing Instrumentation] Adds instrumentation at Transport Layer level #8553
• [Tracing Instrumentation] Adds instrumentation at InboundHandler  #10095
• [Tracing Instrumentation] Add instrumentation at Local Transport Layer #10291

Issues:

• [BUG] The thread context is not properly cleared and messes up the traces #10789
• [BUG] The RestAction names should be templated otherwise the set of operations explodes #10791

@Gaganjuneja it looks to be that we are adding tasks here as we go but we don't see clearly what are the dependencies and priorities (we cannot just instrument arbitrary flows without making sure the flows those are part of are also instrumented). I would suggest to add the following tasks (at least, I am happy to create those):

• [Tracing Instrumentation] Add instrumentation at Local Transport Layer
• [Tracing Instrumentation] Add instrumentation for OpenSearch thread pools
• [Tracing Instrumentation] Add instrumentation for OpenSearch tasks management

@reta, Thanks. I have created the tasks and updated here.
