Fail over?

I believe you could use something like a proxy (Squid maybe?) for clients to
connect to and then use one or the other.  I'm not familiar at all with
squid itself so I may be completely off, but a load balancer does sound like
an option.

So, how are others doing this? I have a server set up here in my
primary data center. We're monitoring a few thousand hosts right now
with a large number of custom externals.

I've been tasked with setting up a fail-over or disaster response
server in case our primary data center has issues. All of our clients
are currently configured to send their messages to the IP address of
our primary server.

Now, I could just copy the bb-hosts file to the DR site, but then I
would only get the network tests since the clients all report to the
primary.

I run two completely separate systems in parallel, and have the clients
report to both of them. The system at our disaster center has the paging
module disabled (just disable the [bbpage] section in hobbitlaunch.cfg),
to avoid double alerts - it is simple to activate it, if necessary.

I was thinking of using Sun Cluster(hb on Solaris) or HeartBeat(hb on
Linux) but
then how can I configure the Cluster solution to failover from one
site(Florida) to another(NewYork) ?


I believe this setup is the most simple failover solution at the only
expense of extra
network bandwidth usgage to the secondary hb server.

tj

Config files are rsync'ed from the primary site to the disaster site
regularly.
