+1 from me (although I've already contributed to osprofiler so my vote might not count, ha). Anyway, people can poke me as well if they have any questions about osprofiler and boris isn't around. I'm happy to answer any questions as well...
Thanks boris for getting this rolling again... Another question, do we need to talk with the people doing the request_id integration into clients to make sure that the trace_id (or whatever its called) is returned to clients... I believe that was one of the original complaints/questions, is that with osprofiler there is now 2 trace like headers (https://github.com/openstack/osprofiler/blob/master/osprofiler/web.py#L36) and such being sent around, should we nail that down now and put that complaint/question to bed? -Josh On Mon, Nov 9, 2015, at 02:57 AM, Boris Pavlovic wrote: > Hi stackers, > > Intro > ------- > > It's not a big secret that OpenStack is huge and complicated ecosystem of > different > services that are working together to implement OpenStack API. > > For example booting VM is going through many projects and services: nova-api, > nova-scheduler, nova-compute, glance-api, glance-registry, keystone, > cinder-api, neutron-api... and many others. > > The question is how to understand what part of the request takes the most of > the time and should be improved.
