Hi,
I have the following scenario. I have an application consisting of
multiple VMs on different compute hosts. The admin puts one of the
hosts into maintenance mode (nova-manage service disable ...) because
there will be some maintenance activity on that host in the near
future. Is there a way to get a notification from Nova when a host
is put into maintenance mode? If it is not the case today would the
nova community support such an addition to Nova?
As a subsequent question is there a way for an external system to
listen to such a notification published on the message bus?
Hi Gibi!
I don't believe there is a notification currently sent when a service is
disabled. I agree this would be a good (and pretty easy) addition to Nova.
Please feel free to add a blueprint in Launchpad. I don't see this as
needing a full spec, really. It shouldn't be more than a few lines of
code to send a new notification message.
Best,
