Hey guys I'm trying to create a dashboard that shows any host with a group of specified hosts that are not returning data from a specific source type

So what I have been trying so far to no success is 

Index=xyz Host=abc  Sourcetype=def 
|  timechart span=30min count by host
Where count < 1
usenull=f useother=f

This won't show anything because it going to have no events to report but I'm not sure how I can create a variable base upon have no results back within a specific time then do a timechart base upon the new variable by host

Unless I'm going about this completely wrong lol please help

Finding something that is not there is not Splunk's strong suit.  See this blog entry for a good write-up on it.
