Collector Status Alerting

The settins/collectors pages show alert ahainst collectors e.g. Watchdog etc. However these alerts do not appear in the general Alerts GUI or against the collector host resource.

We have some single collectors that when fail will cause all the resources underneath to alert (host Status). However I would like an alert agains the collector or its host that can be sent to ServiceNow (I do not want a Host Status alert for each resource under a single collector to raise a ticket). I simply want the alert that is generated (collector Down) in the escalation chain to be visible in the GUI with it's ServiceNow ticket. 

I can see it in the Integration Log(ServiceNow) with a ticket reference generated but this is time consuming and not visible to all users.
