The failover script is used in a scenario where you have two servers
running the network tests - and ONLY the network tests, not the Hobbit
display - each reporting to their own Hobbit server.  If the primary 
network test server server goes down then you want the backup server to
automatically start feeding the test results to both servers. In that case 
it becomes necessary to have a failover from the primary to the backup
server to do the network tests, and that is what the script I posted
does.

But in both scenarios you'd probably want to have the "full picture" of
the health of your systems, so you do need to have the data from the
clients available, both on the primary and on the backup system.
Therefore the clients should be configured to send data to both systems.
