[hobbit] Intelligent alerting across multiple servers?

[j.sansford at ntlworld.com]

TJ, we have 3 data centres and each data centre contains a xymon server. All clients in a data centre only report to their local xymon server. However the xymon servers can communicate with each other using BBDISPLAYS (its a little more complicated than that as we utilise a bbproxy in each DC to take the messages and spray them to all 3 xymons).
