Agreed.

Agreed again

It seems the role is doing a lot of things, but things can be
conditionally triggered. Wondering if this role shouldn't be split into
multiple roles... But that's a different story.

I think this doesn't need to be in the role. Make the role the simplest
as possible, and flexible enough to get passed the list of things to
log/not log, and the destination. OSA can pass a list of files it wants
to gather. But isn't that what the role already does? Or did I
misunderstood?

Can we simply rely on ansible inventory, and running a play with the
role (targetting all) would gather logs for all systems (aio,
multinodes, containers), each system
could go into their own directory (log folder would be <something>/{{
inventory_hostname }}/...) for example:
aio1/<files gathered>
aio1-nova/<files gathered>
machine2/<files gathered>
It simple enough. But I am happy to see a different approach.

Thanks for tackling that up!
I am looking forward a simple common file gathering :)
If you need to do changes in the role (to implement new features),
maybe it can help you if I give you a prio list :)
What I am _generally_ looking for in the logs:
- The ara reports
- The tempest report
- The /etc/openstack_deploy/
- The /var/log/ for containers/hosts
What I am _sometimes_ looking for in the logs (so less important/more
contextual for me):
- ram/disk usage per host
- NICs details
- cpu features (but I am not sure we really need this anymore)
- host details (generally zuul does that for me, so no need to
implement something there)
