> FYI, OSprofiler provides functionality to generate a trace per request, that goes

> This trace can visualize flow of a request [1] [2].
> A trace from OSprofiler can help us know these things:
>     - Performance bottle-neck of a service
>     - Trouble-shooting issue in a service
>     - Understanding flow of a request (from cli client or other client)
>     - Trace can be store in persistent storage
>     - Visualization trace flow in many OpenTracing compatible tracer [2] (will be done
> soon)
>     - Head, tail-based sampling for reducing overhead [3]
>     - Asynchronous tracing [4]

> OSprofiler has already been in most of main OpenStack services such as: Nova,
