Open Stack

Agree with this approach. The large-scale test scenario configuration manual is very meaningful.



When the OpenStack deployment scale reaches a certain level (for example, nodes >= 200,500… etc.),

various exception scenarios will occur, rabitmq blocking conditions, and create a batch of servers.

It’s success rate (There will be some configurations to be care. e.g. scheduling policies, rpc wait time, amount of works etc.).

If there is a reference manual, this is very friendly.

   Hi Matt,



   My name is Joe - docs person from years back - this looks like a good initiative and I would be up for documenting these settings at scale.



   Next step I can see is gathering more Info about this pain point (already started :)) and then I can draft something together for feedback.
