Diagnostic snapshot should have convenient dirs structure

Structure is inconvenient. For example,
localhost node-3.domain.tld node-4.domain.tld
- what is localhost? Why not to call it by it's fqdn or just fuel-master?

Then, when you go to particular node, let's say node-3, you expect to see in that folder everything from it. I see only this:
commands etc
and no other logs.

It's not obvious that logs are actually here: localhost/var/log/remote.

If possible, better structure would be something like:

ls fuel-188...../
remote_nodes fuel-master

ls remote_nodes
10.20.0.6 node-1.domain.tld node-5.domain.tld

ls node-1.domain.tld
bootstrap etc install
ls etc:
sysconfig astute.yaml
