Hi all,
I have 3 monitors in my cluster but 1 of them is a backup and I don't
want to use it as master (too far and on a server where I want to save
resources for something else ...)
But as I can see, mon priority is based on IP (lower to higher, if I'm
not wrong).
I would like to know if it's possible to add a "priority" to my MONs
to select which one I want in case of healthy cluster?
There's not currently a way to do this other than by massaging the IPs
as necessary. I created a new ticket:

It might also be relevant to mention that there's no such thing as a
'backup' monitor per se.
Certainly by not being the leader it will not be subjected to as much
load, but it will participate in quorum decisions and if it
under-performs will affect the whole monitor cluster -- which may not be
noticeable, but can also be a source of several issues especially if by
'too far' you mean considerable latency will be involved.
