Thomas Bechtold add4794120 Don't fail if sqlalchemy driver fails to initialize 
Given that the driver is initialized during the service
startup (eg. like Keystone, Nova, ...) a osprofiler driver failure has
a huge impact on the service (when the driver fails, the whole service
is not usable).
We want to avoid that and just log error/exceptions but keep the
services running.

OSProfiler -- Library for cross-project profiling library

Latest Version

Downloads

OSProfiler provides a tiny but powerful library that is used by most (soon to be all) OpenStack projects and their python clients. It provides functionality to be able to generate 1 trace per request, that goes through all involved services. This trace can then be extracted and used to build a tree of calls which can be quite handy for a variety of reasons (for example in isolating cross-project performance issues).
