Alert when Datasources are not present on a device

I'm not 100% but I do believe that removing a DataSource will clear the alert as revoked which will not send a clear to ticketing (really annoying). I'm not sure and suggest you test that. If that is the case then you can likely code equivalent AppliesTo functionality into custom script code with a bit more work and have it return different values instead.

Ah, I've forgotten how minimal monitoring originally worked. I think I ended up making it into a DataSource a while back using the process we are talking about. I only use it when onboarding new customers which has ticket creation blocked so I don't run into the revoke thing.
