Latest version of utils.py nova API issue on OSP7 (kilo)

Hello,
I'm comparing the previous version of utils.py [1] to the current version of it [2]

/usr/bin/oschecks-check_nova_api --os-username sensu --os-password sensu --os-tenant-name monitoring --os-auth-url http://10.15.11.55:5000/v2.0

*) With version [1] on OSP7, I get this result:
-------------------------------- CUT HERE ----------------------------------------------
OK: Get flavors, nova API is working: list 6 flavors in 0 seconds.|response_time=0
-------------------------------- CUT HERE ----------------------------------------------

*) With version [2] on OSP7, I get this result:
