Let me see if I understand. You have several bb servers at one datacenter, each with their twin at the other datacenter, and both sets do the tests. They report to one central display server, but only one set reports at a time, depending on failover state, correct?
Is this failover automatic? If so, how is this failover determined? What if this failover has a false positive? If not, what is your timeframe to swap over?

Hello list,
It's that time of year again - we're looking for alternatives to our aging bb infrastructure - although it's been helped by the bbgen extensions, it is showing it's age, and is getting harder to support as time goes by.
Of all the potential replacements we've looked at, I don't really like any of them - the commercial bb stuff is uninspiring, and their linux support is lacking. The other solutions tend to be heavyweight j2ee and database apps, or oddities like nagios. What I'd really love to find is something like an up-to-date version of big brother+bbgen, something like hobbit.
Unfortunately, last I checked, hobbit still lacked a crucial capability that we depend on, the built-in bb failover mechanism. We have 2 data centers, several hundred miles apart, with bb servers in several lans at both sites. Each bb server has a twin at the other location, and they both monitor the servers in both data centers, but only one of the bb servers does reporting, as determined by the failover state. The bb failover has worked marvelously, and has kept bb firmly in place so far, despite the other advantages of hobbit.
So, the $64 question: Is there anything in hobbit, or on the horizon, which will allow hobbit to serve as a drop-in replacement for bb, including the failover capability?
Thanks for your words of wisdom.
Joe
