One of the things we really make use of in our current bb setup is the failover capability, which has been quite useful on more than one occasion.
We have 2 geographically separate data centers which are connected via a fat pipe, and we do redundant monitoring of each data centers via bb servers from each data center. The bb servers in data center 1 normally does all the alerting, but in case the bb servers in data center 2 can't reach the bb servers in data center 1 (for instance in case of wan outage) the bb servers in data center 2 fail over and take on all the alerting duties. If and when the bb servers in data center 1 become reachable again, the bb servers in data center 1 revert to the normal non-alerting state.
I looked through the hobbit configs but don't see that failover functionality. Is that something envisioned for a future release, or is there simply a different approach to that problem in hobbit as compared to bb?
