How to check whether it is neutron or quantum that is in use? [closed]

I am developing an automated testing script for neutron. I want to use callbacks for the previous versions of Openstack which uses quantum and even support that.

How do we identify if it is neutron or quantum that's in the use in a machine?

just another 2 cents on this. Best way to check even if everything is down i.e neutron/quantum, keystone etc is 1. Check for /etc/neutron or /etc/quantum directory. Easy to script in your scripting code 2. Check for the neutron or quantum database. This requires more code.

It depends on which openstack version you have installed on the machine. If it is Folsom or Grizzly then you could see quantum else neutron for Havana or ice house releases.

use quantum help ( Folsom and Grizzly) neutron help ( Havana and ice house) on CLI

look for entry in nova.conf  - network_api_class =
look for directory /etc/neutron or /etc/quantum
ps -aef | grep neutron-server or qauntum
you can decide based on the nova --version as well.

Many more. All of them are indirect way of getting it. There is no API call to get what you are running.
