[Linux-HA] Redirecting when resource is down

I've now got a basic heartbeat installation up and running with virtual
ip address on a two node Tomcat cluster and it is basically just great!
Obviously, now that the basic failover is up and running, i'm looking to
configure it just a little bit more.
The default heartbeat config means that if the heartbeat daemon goes
down, the dc node will switch and then the virtual ip address will point
to the second Tomcat instance, and this obviously will include if a
complete server dies. However, if I want to take an instance of Tomcat
down for maintenance, I would still want the heartbeat to failover,
while I upgrade, until I start Tomcat back up again, so i'm looking for
something that would monitor Tomcat as well as just the node.
I think ldirectord would do this, but do you have to install LVS as
well? I looked at the Tomcat native resource but that appears to start
and stop the Tomcat, which is not what I really need. Is ldirectord
what I need?
Thanks in advance.
