[hobbit] dr for hobbit

[Krash, Paul]

Overcome this  by checking if BBDISPLAY server is down,
then editing client config file, bouncing hobbit service.

No delays/responsiveness issues.

Much the same as hobbit invokes an email or SNPP
event that notifies user if up or down,
one could notify clients that a BBDISPLAY is down/up
and act accordingly.

Best,

PKrash

Hi,

just a note on that one, we are running a setup like that too, plus a
third host for alerting. The problem we have is that if one of the
hosts in BBDISPLAYS is down, clients will have trouble sending in data
to any server, because of timeouts. Sometimes notifications lag for as
much as half an hour.

I'm not saying your setup won't work, but you should keep in mind that
you might effectively degrade availability/responsiveness because of
the use of multiple servers.
