Usually you would use the `--debug` parameter on the client (this works
not only on the openstack common client but also on individual service
clients), then you'll see what REST API entries are being called on the

in debug mode) and see the code path these are following.
If you want to follow a particular tenant/project and user it will
depend on the configured logging format, but they usually include the
project_id or project_name and the user_id or user_name.
Also, on the server side most projects have an "api" directory where all
