Why would you want to monitor DB Nodes using heartbeat ?
The Management node is the place to put monitoring on, as
it gathers all data from all DB Nodes, to my oppignon.
Extracting monitoring information directly from the management
node allow direct text operations while coding the "monitor".
Ok, supposing that you monitor directly the DB Nodes, what about
mysqlping enabled version ? is there such a tool already ?
