francotseng 6c035399ad Bring env OSPROFILER_CONNECTION_STRING into effect 
The --connection-string is marked required, and parse_args()
assumes the flag invalid if it's not supplied as command line
argument, even if env OSPROFILER_CONNECTION_STRING is setted.

We should not rely on the required=True of argparse module,
but check the required args on our own to take env arguments
into consideration.

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).
