[Linux-HA] Monitoring a monitored application

I have the following scenario to attempt to implement:
- The key resource of interest is a web-based application running within
- There are two nodes to be set up with the application in an
- Only one of the nodes can have the application fully enabled at any
given point in time
- A pair of load-balancing network devices monitor both of the nodes to
determine whether the active one is still alive and the passive one is
capable of taking over if needed.
At the moment I am considering having Tomcat start up before heartbeat,
and just having the web application (controlled from an OCF script) as
the only resource. However, in the event of a failure on the active
node I will still need some way of making the transfer of the resource
between nodes to be detectable by the load balancers.
Has anybody struck a similar situation?
