Ok, I better understand it. I thought you were doing 2 separate worlds but
with a common view. In fact you want a simple HA ? By default, all is
checked from the site A (but you can have poller_tag, so the checks for site
B are launch by a poller in site B, with a site A spare), and if the site A
fail, there are spares in the site B.

The question was the Ninja UI in fact, and so the databases. With a HA
installation (so master in A, spare in B) you will get all data in A
database, and if A failed, spares in B will take the lead, and the B-broker
will 'regenerate' the merlin database and so the B-Ninja will still work
(without a restart).
The fail back (when A will came back) will need a restart from now (should
be enable by an option one day :) ).
Sounds good for you?

All the data continuously generated in your IT infrastructure contains a

sense of it. Business sense. IT sense. Common sense.
