Hey all,

Thanks for your replies.
About the fact that nova already implement this, I will try again on my
side, but maybe it was not yet implemented in newton (I only tried nova
on newton version). Thank you for bringing that to me.

About the healhcheck already done on nova side (and also on neutron).
As far as I understand, it's done using a specific rabbit queue, which
can work while others queues are not working.
The purpose of adding ping endpoint here is to be able to ping in all
topics, not only those used for healthcheck reports.

Also, as mentionned by Thierry, what we need is a way to externally
do pings toward neutron agents and nova computes.
The patch itself is not going to add any load on rabbit. It really
depends on the way the operator will use it.
On my side, I built a small external oslo.messaging script which I can
use to do such pings.

Cheers,
