Customizing HostStatus datasource to alert on "No Data" ???

Can anyone share some feedback on customizing default global definition behavior for datasource HostStatus (HR6FND)? More specifically, I'm looking for some ideas about changing the behavior ...

    The HostStatus datsource should always have data, even if the device is not responding. We have a >300 threshold on the idleInterval datapoint. 

    I've thought about making an SNMP troubleshooter, but that would be so similar to the SNMP_Host_Uptime DS that i then thought about just putting a no data alert on the Uptime datapoint there. I never actually did it, but I may do in the future. Should be the canary for SNMP monitoring.

After a little further review, the newest SNMP_Host_Uptime datasource is probably the best choice.   It seems to be a universal hit in terms of both "AppliesTo" matching and returning valid data to polling/collection.  snmpTCPUDP (TCP UDP stats) seems also universal in terms of "Applies To", but some of our devices return "No Data" 24/7.  In addition, I have not been able to positively identify a historical situation where an snmpTCPUDP alert trigger on"No Data" would have produced the desired result, i.e. making us aware of the situation when other SNMP datasources were not doing so.
