I believe that such a solution (read to install) should exist.
Unfortunately I don't know the magic keywords to find it:
I have a group of hosts with different IPs offering the same services.
I'm able to install some agents on them for monitoring their
network/cpu/number of users/whatever utilization. I'm wondering if there
is an option for BIND9 to obtain those load parameters on a regular
basis (let's say: every 10 minutes) and when queried for the A record
return ONLY one IP address - the one of the server with the lowest
utilization?
It can be implemented on those servers but in the solution I'm asking
about the key point is that the BIND server takes the decision.
this can't work - only a minority of clients is asking your nameserver
directly, most talk to caches
you try to solve the problem on the wrong side
you need a loadbalancer in front of the cluster
