AnsibleUndefinedVariable: {{ ansible_processor_vcpus }} when running role

[jlownie]

We ran the role (v1.0.2) on a host and got this error message:

ASK [lae.netbox : Configure uWSGI NetBox application] **************************************************************************************************************************************************************************************
fatal: [xxx.sol1.net]: FAILED! => {"changed": false, "msg": "AnsibleUndefinedVariable: {{ ansible_processor_vcpus }}: 'ansible_processor_vcpus' is undefined"}

The variable ansible_processor_vcpus isn't referenced in that task but it is referenced in defaults/main.yml:
netbox_processes: "{{ ansible_processor_vcpus }}"

We changed it to this and it worked:
netbox_processes: "{{ ansible_processor_vcpus | default(4) }}"

I'm not sure why that var is undefined - from what I've read it's supposed to be set automatically somewhere. So I'm not sure if what we've done is the best solution but I'm happy to submit it in a pull request if people think it's OK.

That change is fine I think, but I believe default(1) would be more appropriate here—wouldn't make too much sense to set it to 4 for example on a 1 core virtual machine/VPS.
