OpenStack Rocky : Configure Aodh2018/09/19 |
|
Install OpenStack Alarming Service (Aodh).
This example is based on the emvironment like follows.
Gnocchi package of Ubuntu OpenStack uses WSGI with Python3, but other OpenStack components like Keystone or Aodh uses WSGI with Python2, so their WSGI package conflicts and cannot install them all on a Node.
