Integrate OSprofiler in Keystone
OSprofiler is an Oslo library dedicated to enable cross-service
OpenStack profiling. This makes possible to trace the OpenStack
request through all projects supporting the library, where the
profiling is enabled, and generate JSON and HTML human-readable
reports, describing what time was spent on which operation, e.g.
API or DB request.
This change inclues the following:
* Add settings for OSprofiler wsgi middleware
This middleware is used for 2 things:
1) It checks that person who want to trace is trusted and knows
secret HMAC key (that is specified in paste.ini).
2) It initalize profiler in case of proper trace headers
and add first wsgi trace point, with info about HTTP request.
* Init profiler on start in both cases (httpd or eventlet)
* Adding new conf group for profiler (to enable/disable)
* By default osprofiler is disabled
TBD:
* Adding trace point for all DB (sql) calls. For proper format and
result oslo.db enginefacade module needs to be updated.
To test (old variant, will be changed with new commit to the
python-openstackclient):
$ . amdminrc # you should be admin user/tenant to fetch profiling data
$ keystone --profile SECRET_KEY user-list
$ osprofiler trace show --html --out result.html <TRACE_ID>
