Chris,
We working on cross service project profiler OSprofiler [1] and integrating
it in all projects (including gates)
Please join discussion here: https://review.openstack.org/#/c/103825/
If everting goes well we will get this feature in Juno.
So we will be able to trace request cross service-project with just adding
--profile to any python client call.
And get such results: http://boris-42.github.io/profiler/

Best regards,
Boris Pavlovic

Is there a straightforward way to determine where the time is going when I
run a command from novaclient?
For instance, if I run nova list, that's going to run novaclient, which
will send a message to nova-api, which wakes up and does some processing
and sends a message to nova-conductor, which wakes up and does some
processing and then calls out to the database, which wakes up and does some
processing and sends the response back to nova-conductor, etc... And the
messaging goes via rabbit, so there are additional messaging and wake-ups
involved there.
Suppose nova-list takes A amount of time to run...is there a standard way
to determine how much time was spent in nova-api, in nova-conductor, in the
database, in rabbit, how much was due to scheduler delays, etc.? Or would
I be looking at needing to instrument everything to get that level of
detail?
