Don't you think this is more or less the meaning of having a "bigger"
like Nagios - to handle such things ?
For me it sounds like another approach to reinvent the wheel.
I'd suggest writing a simple nagios check would be a lot easier - there
you can even fire up
actions if necessary such as trigger a failover between your
loadbalancers or similar.

The digest function is not supported in Nagios while you can define to
be only notified once
while a service is in state Critical.
