IMHO it does not make sense to have failure-timeout smaller than the monitoring interval; I'd say use at least two monitor intervals; otherwise you are basically disabling the monitoring. Usually reasonable values are probably hours or days, depending on the stability of your cluster.

Syntax is very easy (says the manual):
           Example:

               trace fs start
               trace webserver
               trace webserver probe
               trace fs monitor 0
