From my admin-view:
I wonder about the benefits of that (and if work shouldn't be put into other usefull things). If no monitoring is connected / some autonotify via E-Mail or such, to me it's rather useless. I don't really care since when a device is broken, when it already happened $somewhen ago - I need ASAP notify of it, when it happens. Like some health monitoring for XCP, however realized (via XenCenter, central Mail service, SNMP, Nagios/Montoring plugins...)
