monitor and failure detectors

[Johan Montelius]

Some question on monitors:

Is there a way to change the timeout of monitors to configure how eager  
they will be to deliver a DOWN/noconnection message? Can this be changed  
on a per monitor basis so one could monitor one process with a 0.1s  
timeout and another with a 20s timeout?


I guess it is the empd daemon that is responsible for tracking the state  
of nodes on a host. If a node crashes a monitor will report  
DOWN/noconnection. Could it be possible to have monitor generate a  
DOWN/down or similar when/if it can be determined that the node (and thus  
the process that we monitor) is actually down. The DOWN/noconnection  
message leaves us in a state where we don't know it is down or simply  
disconnected.
