Shouldn't we make these Warn or maybe Debug?

not sure if Warn would address the log noise concerns folks are reporting, I am fine with both Debug or Info. @tjhop what do you say?

I still think it should be debug.

For these error check cases where we're continuing on, I think going with debug logging makes sense in context here -- we would only really care about them if we needed to troubleshoot the entire flow of the probe. For the error checks where we actually stop and return, I think those should remain at error level, though.
